用于外科缝合器的具有击发锁定的外科缝合头组件 The surgical stapling head assembly for a surgical stapler having a firing lockout

背景技术 Background technique

[0001] 本发明实施例总体涉及外科缝合器,并且更具体地讲,涉及包括分立缝钉高度调节的圆形缝合器。 [0001] The present invention generally relates to embodiments of surgical staplers, and more particularly, relates to a staple height adjusting including discrete circular stapler.

[0002] 在某些类型的外科手术中,使用外科缝钉已成为连接组织的优选方法,并且因此已开发了用于这类用途的具有特殊构造的外科缝合器。 [0002] In certain types of surgical procedures, the use of surgical staples has become the preferred method of joining tissue, and thus surgical staplers have been developed for such applications have a special configuration. 例如,已经开发了用于被称为吻合的外科手术的腔内或圆形缝合器。 For example, have been developed for surgical procedures is known as a cavity or circular anastomosis stapler. 用于施行这种吻合的圆形缝合器在(例如)美国专利如.5,104,025;5,205,459;5,285,945;和5,309,927、以及美国专利申请序列如.12/408, 905中有所公开,这些专利文献均全文引入本文以供参考。 For the purposes of this circular anastomotic staplers in (e.g.) such as U.S. Patent No. .5,104,025; 5,205,459; 5,285,945; and 5,309,927, and U.S. Patent Application Serial such as .12 / 408, 905 are disclosed, these Patent Documents They are incorporated herein by reference.

[0003] -种类型的吻合包括先切除患病部分然后将肠的各个段连接到一起的外科手术。 [0003] - types of agreement include the first removal of diseased portions of each segment of the intestine and then connected together surgery. 该手术需要将两个管状部分的末端重新连接到一起,以形成连续的管状通道。 This procedure requires the two ends of the tubular portion reconnect together to form a continuous tubular pathway. 以前,这类外科手术既费时又费力。 Previously, this type of surgery is time-consuming and laborious. 外科医生必须准确切割和对齐肠的两端,并且在通过多次缝合将两端连起来时保持对齐状态。 The surgeon must be accurate cutting and alignment of both ends of the intestine and maintain alignment state by repeatedly stitching together the ends even when. 圆形缝合器的开发大大简化了吻合程序,并且也缩短了执行吻合所需要的时间。 The development of circular staplers greatly simplified the anastomosis procedure and also reduces the time required to perform the anastomosis.

[0004] -般地,常规圆形缝合器通常由安装于其上的近端驱动机构和远端缝合机构的细长轴构成。 [0004] - In general, a conventional circular stapler typically consists of an elongated proximal end of shaft drive mechanism mounted thereon and a distal stapling mechanism. 远端缝合机构通常包括固定的钉仓,钉仓内含有构造成同心圆阵列的多个缝钉。 Distal stapling mechanism typically comprises a fixed staple cartridge within the cartridge configured to contain a plurality of concentric circular array of staples. 圆形切刀在缝钉内被同心地安装在钉仓中以用于在其内轴向行进。 Circular cutter is mounted concentrically within the staples in the staple cartridge for axial travel therein. 从钉仓的中心轴向地延伸的是可动的套管针轴,该套管针轴能够将缝钉砧座可脱离地联接到其上。 Extending axially from the center of the staple cartridge is movable trocar axis, the trocar shaft staple anvil can be releasably coupled thereto. 在将缝钉驱入砧座中时,砧座能够使缝钉的末端成形。 When the staple is driven into the anvil, the anvil is possible to end the staple forming. 钉仓远端表面与缝合砧座之间的距离由调节机构控制,而调节机构安装在缝合器轴近端以控制套管针的轴向运动。 From the distal end surface of staple cartridge stapling anvil by adjusting the control means, and the adjusting mechanism mounted on the proximal end of the stapler shaft for controlling the axial movement of the trocar. 当外科医生启动驱动机构时,对夹在钉仓和缝合砧座之间的组织同时进行缝合和切割。 When the surgeon activates the driving mechanism of sandwiched between the cartridge and anvil stapling tissue suturing and cutting simultaneously.

[0005] 通常,在执行外科吻合缝合手术中,两段腔管或管状组织,例如肠组织,通过缝钉环附接在一起。 [0005] In general, the implementation of a surgical anastomotic stapling operation, two lumen or tubular tissue, such as intestinal tissue by the staple ring attached together. 两段管状组织可以端对端附接,或者一段管状组织可以围绕形成在另一段管状组织侧面中的开口横向附接。 Two tubular tissue may be attached end to end, or a period of tubular tissue can be formed around a tubular tissue in another section of the side of an opening in the lateral attachment. 在用缝合器械执行吻合的过程中,两段管状组织一起被夹在砧座和钉仓之间。 In the process of carrying out anastomosis suture instrument, the two tubular tissue is clamped together between the anvil and the staple cartridge. 缝钉推动器被推进以将缝钉驱入组织中并且抵靠砧座成形缝钉。 Staple pusher is advanced to drive the staples into the tissue and against the anvil shaped staples. 另外,圆形刀被推进以切割夹在砧座和缝钉夹持器之间的多余组织。 In addition, the circular knife is advanced to cut sandwiched between the anvil and the staple holder excess tissue. 因此,组织的环形部分被从每个腔管切断并且保留在砧座轴上。 Thus, the annular portion of the tissue is severed from each lumen and remains in the anvil shaft. 通过朝远端推进砧座轴以使砧座运动远离缝钉夹持器,使通过圆形缝钉环连接的管状组织松开。 By advancing the anvil shaft distally to move away from the anvil staple holder, the tubular tissue by a circular ring connected staple release. 牵引砧座通过由缝钉环附接的管状组织段之间的圆形开口,从而将缝合器械取出。 Pulling the anvil through the circular opening of the tubular section of tissue from the staple ring attached between, so as to remove the stapling instrument.

[0006] 此外,使用圆形缝合器执行下部结肠手术时,通常采用常规的外科缝合器缝合肠, 这种缝合器在待移除肠的患病部分两侧安置两排缝钉。 [0006] In addition, when using the circular stapler to perform lower colon surgery, typically using a conventional surgical stapler stapling intestinal, such suturing device to be disposed on both sides of diseased section of the intestine to remove two rows of staples. 在缝合相邻末端的同时切除目标段。 While the adjacent ends of the suture removal target segment. 移除患病部分后,外科医生通常将砧座插入腔管近端,即缝合线近端。 After removing the diseased part, the surgeon typically inserts the anvil into the proximal lumen, namely the proximal end of the suture. 这可通过将砧座头部插入外科医生在近腔管切开的入口来完成。 This is done by inserting the anvil head surgeon lumen near the inlet to complete the cut. 有时,砧座可经肛门放置,即通过将砧座头部放在缝合器的远端上并通过直肠插入器械。 Sometimes, the anvil can be placed through the anus, which anvil head by placing the distal end of the suturing device is inserted through the rectum and instruments. 然后外科医生可用缝线或其他常规的系结装置将肠的近端系在砧座轴上。 The surgeon then sutures available or other conventional tying device proximal intestine tied to the anvil shaft. 接着,外科医生切除系结处附近多余的组织,并且外科医生将砧座附接到缝合器的套管针轴上。 Next, the surgeon removes excess tissue at bind nearby, and the surgeon will be attached to the stapler anvil trocar shaft. 然后外科医生合拢砧座和钉仓之间的间隙,从而将肠的近端和远端夹紧在间隙中。 The surgeon then closed the gap between the anvil and cartridge, thereby clamping the proximal and distal intestine in the gap. 外科医生随后启动缝合器,从而驱动多排缝钉穿过肠的两端并使其成形,因此接合末端并形成管状通道。 The surgeon then starts the stapler, thereby driving the rows of staples through the two ends of the intestine and shaping it, and the joining end to form a tubular passage. 同时,在驱动并成形缝钉时,可驱动同心的圆形刀片穿过肠组织末端,从而切割邻近内排缝钉的末端。 Meanwhile, in the driving and forming the staples can be driven through a concentric circular blade intestinal tissue ends, so that the cutting tip is adjacent to the inner row of staples. 接着,外科医生从肠中取出缝合器, 并完成手术。 Next, the surgeon remove the stapler from the intestine, and to complete the operation.

[0007] 在上述外科手术期间,希望在缝钉高度范围内正确地成形缝钉,使得它们保留在组织中并防止渗漏和出血,并且希望实现"组织与组织"接触以促进组织愈合。 [0007] During the above-described surgical procedure, we hope that within the scope of staple height correctly shaped staples, so that they remain in the organization and to prevent leakage and bleeding, and hope to achieve "tissue and" engagement to promote tissue healing. 通常,通过控制砧座和钉仓之间的距离或间隙,可以实现更好的缝合和愈合结果。 Generally, by controlling the distance or gap between the anvil and the cartridge can be achieved better stitching and healing results. 虽然一些外科缝合器装有指示缝钉高度的可视读出器,但外科医生可能需要在手术期间专注于许多不同的事项。 While some surgical stapler provided with a visual indication of the staple height readout, but may require the surgeon during the procedure to focus on a number of different considerations. 此外,一旦砧座已正确定位,就有必要使砧座在击发期间不运动,否则可能负面地影响正确的缝钉成形。 In addition, once the anvil has been positioned correctly, it is necessary that the anvil does not move during firing, it may adversely affect the proper staple formation.

[0008] 以上讨论仅仅旨在说明本发明所属领域的现状,而不应视为是对权利要求范围的否定。 Discussion [0008] The foregoing merely intended to illustrate the present invention belongs to the field of the status quo, but should not be considered Is the scope of the claims deny.

[0047]参见图3和4,驱动系统可包括驱动带80,驱动带80位于主体的轴部12内部,在触发器的凸轮表面94和缝合头30的接片36之间轴向延伸。 [0047] Referring to Figures 3 and 4, the drive system may include a drive belt 80, drive belt 80 located inside the body of the shaft portion 12, extending in the axial direction between the cam surface 36 of the trigger 94 and the tabs 30 of the stapling head. 驱动带80可包括近端驱动表面81和远端驱动表面82。 Drive belt drive surface 80 may include a proximal end 81 and a distal drive surface 82. 因此,启动触发器可使凸轮表面94旋转并推动近端驱动表面81,使得驱动带80在轴向上朝着或远离砧座50运动。 Thus, the start trigger can rotate the cam surface 94 of the proximal end of the drive and driven surface 81, so that the drive belt 80 in the axial direction toward or away from the anvil 50 sports. 缝合头的接片36可联接在驱动带的远端驱动表面82 内,远端驱动表面82可采用凹口的形式以便可释放地容纳接片36。 The stapling head tab 36 may be coupled at the distal end of the drive belt 82 drives an inner surface, the distal surface 82 may be in the form of drive recess to releasably accommodate tab 36.

[0048] 参见图4和7A-7C,缝合头30可包括组件,该组件包括:钉仓33,其用于支撑一个或多个缝钉31;至少一个缝钉驱动器34,用于接合和驱动来自钉仓33的缝钉31;以及切割构件32(例如刀),其可动地支撑在缝合头30中。 [0048] Figures 4 and 7A-7C, the suture 30 may include a head assembly, the assembly comprising: a staple cartridge 33, for supporting one or more staples 31; at least one staple driver 34 for engaging and driving staples from staple cartridge 33, 31; 32 and a cutting member (e.g. a knife), which is movably supported in the stapling head 30. 在至少一个实施例中,缝钉驱动器34和切割构件32可以一体地连接和/或形成。 In at least one embodiment, the staple driver 34 and the cutting member 32 may be integrally connected to and / or form. 例如,缝钉驱动器34和切割构件33可从芯35中伸出,并且二者都可由相同材料形成。 For example, staple driver 34 and the cutting member 33 may extend from the core 35, and both can be formed of the same material. 在任何情况下,驱动带80朝向钉仓33和/或砧座50的动作均可引起缝合头的接片36(可从芯35中伸出),以及切割构件32和缝钉驱动器34朝砧座50运动。 Tabs In any case, the drive belt 80 toward staple cartridge 33 and / or actions can cause the anvil 50 of the stapling head 36 (which can be extended from the core 35), and a cutting member 32 and staple driver 34 toward the anvil Block 50 sports. 此外, 缝合头30也可包括壳体39,该壳体能够保持钉仓33并在其内可动地容纳缝钉驱动器34、切割构件32,和/或芯35。 In addition, the suture head 30 may also include a housing 39, the housing 33 and capable of holding the cartridge therein movably accommodated staple driver 34, the cutting member 32, and / or the core 35. 壳体39还可包括释放按钮37,该释放按钮能够柔性地挠曲并允许缝合头30在形成于主体轴部12中的对应孔15(参见图3)处可释放地附接到主体的轴部12。 Housing 39 also include a release button 37, the release button can flex and allow the flexible stitching head 30 in corresponding holes formed in the body portion 12 of the shaft 15 (see FIG. 3) is releasably attached at the axis of the body 12. 因此,参见图4,缝合头30可通过以下方式移走:按下按钮37,然后转动头部30,使得接片36从由驱动带80的远端驱动表面82形成的凹口中脱开,最后将缝合头30拉离主体10。 Thus, referring to Figure 4, the stitching head 30 can be removed in the following way: Press the button 37, then turning the head 30, so that the tab 36 from the recess 80 by the distal end of the drive belt drive surface 82 is formed disengaged, and finally the stitching head 30 is pulled away from the body 10.

[0049] 现在关注砧座50的调节,参见图3,在多个实施例中且如上所指,砧座50可相对于钉仓33被可动地支撑,使得砧座可以朝着和远离钉仓33轴向运动。 [0049] Attention is now anvil adjustment, see Figure 50 3, in various embodiments, and as indicated above, the anvil 50 is movable relative to the cartridge 33 is movably supported, so you can anvil toward and away from the nail 33 warehouse axial movement. 更具体地,外科缝合器1 可包括用于选择性地调节砧座50相对于钉仓33的轴向位置的砧座调节组件。 More specifically, the surgical stapling instrument 1 may include selectively adjusting the anvil 50 with respect to the axial position of the anvil 33 of the staple cartridge adjustment assembly. 砧座调节组件可包括调节轴70和套管针73,该套管针联接到调节轴70,以与调节轴70-起行进。 Anvil adjustment assembly may include adjusting shaft 70 and needle cannula 73, the trocar shaft 70 is coupled to the adjustment to the adjustment shaft 70- from traveling. 调节轴70 可包括近端部分70a和远端部分70b,这两个部分可以连接到一起以形成轴70。 Adjusting shaft 70 may include a proximal portion 70a and distal portion 70b, the two sections may be connected together to form a shaft 70. 作为另外一种选择,近端部分70a和远端部分70b可由同一件材料一体和整体地形成(参见例如图17所示的调节轴170,以及下面的讨论)。 Alternatively, proximal portion 70a and distal portion 70b may be formed integrally with the material and an integrally formed (e.g., see 170, and the following discussion adjusting shaft 17 as shown in FIG.). 另外,调节轴70还可包括位于远端部分70b处的环形凹槽71,该环形凹槽可以被夹住或以其他方式自由连接到砧座调节带72的近端。 Further, the adjusting shaft 70 may also include a distal portion 70b of the annular groove 71, the annular groove may be clamped or otherwise connected to the free proximal end of anvil adjustment of the belt 72. 应当理解, "自由连接"是指在调节轴70旋转时调节带72可不旋转;然而,调节带72仍可以与轴70-起平移。 It should be appreciated that the "free connection" means that when adjusting the rotary shaft 70 of the adjusting belt 72 may rotate; however, the adjusting belt and the shaft 72 can still be translated from 70-. 调节带72的远端也可附接到套管针73。 Adjust with the distal end 72 may also be attached to the trocar 73. 因此,调节轴70相对于主体10的轴向运动或平移可使套管针73也相对于主体10轴向运动或平移。 Therefore, the adjusting shaft 70 relative to the body 10 of the axial movement of the needle or cannula 73 also allows the translation relative to the body 10 or axial movement of translation.

[0050] 参见图3和4,砧座调节带72和驱动带80中的一者或两者可分别包括接片83和84, 这两种接片均弯曲或以其他方式伸向主体10。 [0050] Referring to Figure 3 and 4, the anvil adjusting belt 72 and drive belt 80 in one or both may include tabs 83 and 84, respectively, these two tabs are bent or otherwise toward the body 10. 接片83、84可帮助使带72、80能够行进通过主体的弯曲轴部12,同时填充空间并在其内保持合适的轴向位置。 Tabs 83, 84, 72, 80 can help the belt travels through the main body portion 12 of the bending axis, while filling space while maintaining the proper axial position therein.

[0051] 此外,参见图3和6,如本领域已知,套管针73可通过联接到砧座和/或套管针的簧片或弹簧夹55可脱离地附接到砧座50。 [0051] Further, see Figures 3 and 6, as known in the art, trocar 73 can be coupled to the anvil and / or trocar or reed spring clip 55 is releasably attached to the anvil 50. 换句话讲,通过按压、拉拔或以其他方式操纵弹簧夹55,可从套管针中移开砧座。 In other words, by pressing, drawing or otherwise manipulate the spring clip 55 can be removed from the anvil trocar. 反之,通过使套管针运动进入砧座,使得弹簧夹55将砧座可释放地保持在套管针上,可将套管针按扣入砧座中。 On the contrary, by making the movement of the trocar into the anvil, the anvil 55 so that the spring clip is releasably held on the trocar, trocar snaps into the anvil can be in. 因此,砧座调节轴70相对于主体10的轴向运动也可以相对于主体10轴向运动或平移砧座50。 Thus, the anvil adjustment shaft 70 relative to the axial movement of the body 10 may be with respect to the axial movement of the body 10 or translate anvil 50. 此外,砧座也可包括联接到砧座主体52 的护盖53(参见图3)和在击发切割构件32期间被剪切的垫圈54,如上面所讨论。 In addition, the anvil can also include an anvil coupled to the main body 52 of the cover 53 (see FIG. 3) and the cutting member 32 during firing of the washer 54 is sheared, as discussed above. 垫圈54可由塑料制成并可充当切割表面,组织可以抵靠该表面被切断。 Gasket 54 may be made of plastic and can act as a cutting surface, the surface against which organizations can be cut off.

[0052] 现在参见图3-5,砧座调节轴70能够进行旋转(如上面所述),使得轴70相对于主体10平移。 [0052] Referring now to Figures 3-5, the anvil can rotate the adjusting shaft 70 (as described above), such that the shaft 70 with respect to the translation of the body 10. 更具体地并且在至少一个实施例中,砧座调节轴70可包括螺旋表面74,该螺旋表面可操作地与主体10的接合部(例如,通过主体中的孔固定到主体10的螺销75)接合。 More specifically, in at least one embodiment, anvil adjustment shaft 70 may include a spiral surface 74, the surface of the coil 10 operatively associated with the engaging portion of the body (e.g., through the body of the screw hole is fixed to the main body 10 of the pin 75 ) engaged. 螺旋表面74可由形成于调节轴70中的槽限定,所述槽被构造成并且其尺寸被设定成在其内容纳销75的至少一部分。 Helical surface 74 may be formed on the adjusting shaft 70 defines a slot, said slots being configured and dimensioned to be set in the box in which the at least a portion of the pin 75. 砧座调节轴70可围绕其纵向轴线L旋转(参见图8),使得螺旋表面74接触并在销75上方运动,从而使砧座调节轴70相对于主体10平移。 Anvil adjustment shaft 70 can rotate about its longitudinal axis L (see Figure 8), so that the helical surface 74 of the pin 75 in contact with and moved over so that the anvil adjusting shaft 70 relative to the body 10 translation. 虽然在本实施例中描述了销75,但可以使用任何其他合适的螺纹配合部分或部件(例如突起、螺纹等)来代替或辅助销75接合螺旋表面。 Although the examples described in the present embodiment the pin 75, but you can use any other suitable mating threaded part or parts (such as projections, thread, etc.) or to replace the auxiliary pin 75 engaging helical surface. 在任何情况下,使调节轴70围绕其纵向轴线旋转可以导致轴70,继而套管针73和砧座50也相对于主体10和/或缝合头30轴向平移或运动。 In any case, the adjusting shaft 70 about its longitudinal axis can lead to shaft 70, and then the trocar 73 and the anvil 50 is also relative to the body 10 and / or stitching head 30 or axial translation movement.

[0053]如上面所提及,在多个实施例中,调节轴70能够使砧座50运动至离缝合头30至少一个预定距离处。 [0053] As mentioned above, in various embodiments, the adjusting shaft 70 can be moved to the anvil 50 from the at least one stapling head 30 at a predetermined distance. 更具体地,现在关注图8,其仅示出调节轴70,调节轴的螺旋表面74可包括至少一个斜坡部分和至少一个停顿部分。 More specifically, attention now to Figure 8, which shows only the adjustment shaft 70, adjusting screw surface of the shaft 74 may include at least one ramp portion and at least part of a pause. 例如,螺旋表面74可包括第一斜坡部分74a和一个或多个第二停顿部分74b。 For example, the spiral ramp surface 74 may comprise a first portion 74a and one or more second pause portions 74b. 至少一个限定器,例如限定器76,也可将斜坡部分74a与停顿部分74b分开。 At least one qualifier, such as qualifier 76, can also be part of the slope portion 74a and 74b separated from standstill. 如下面将进行的更详细的讨论,斜坡部分74a可允许调节轴相对于主体10平移(参见图4),停顿部分74b可提供预定距离以维持砧座50距缝合头30的位置(参见图2),并且限定器76可向旋转砧座调节轴70的使用者提供触觉反馈以及斜坡部分和停顿部分之间的过渡。 Discussed in more detail as the following to be carried out, the ramp portion 74a to allow adjustment of the shaft relative to the main body 10 translation (see FIG. 4), a pause portion 74b may be provided a predetermined distance to maintain the anvil 50 positions from the stapling head 30 (see FIG. 2 ), and defines 76 can be adjusted to provide tactile feedback to the rotating anvil and a transition section between the ramps and pauses portion shaft 70 users. 此外,在至少一个实施例中,斜坡部分74a可以在形状上至少部分是螺旋状。 In addition, in at least one embodiment, the slope portion 74a may be at least partly helical shape.

[0054] 接着,图8中以虚线画出的圆表示图9和10A-10C中所示砧座调节轴70的近侧端部分。 [0054] Next, FIG. 8 shows a circle drawn in dashed lines in FIG. 9 and 10A-10C shown in the proximal end portion of anvil adjustment shaft 70. 现在关注图9,螺旋表面74的斜坡部分74a可引导进入至少一个停顿部分。 Attention is now directed to Figure 9, the ramp surface 74 of the spiral portion 74a can be guided into at least a pause section. 如图所示,并且在至少一个实施例中,螺旋表面74还可包括三个停顿部分:第一停顿部分74b'、第二停顿部分74b' '和第三停顿部分74b' ''。 As shown, in at least one embodiment, the helical surface 74 may also include a pause three parts: The first part of the pause 74b ', a second halt portion 74b' ', and a third halt portion 74b' ''. 砧座调节轴70围绕其纵向轴线的旋转可使螺旋表面74 沿销75而过(参见图5),使得轴70相对于主体10平移(再次参见图5)。 Adjusting the anvil 70 to rotate about its longitudinal axis of the shaft 74 can spiral along the surface of the pin 75 and over (see FIG. 5), such that the shaft 70 relative to the body pan 10 (see again FIG. 5). 此外,当轴70按(例如) 顺时针CW旋转时,螺旋表面74可以沿销75运动,使得销75接触斜坡部分,然后接触第一停顿部分74b'。 In addition, when the shaft 70 by (for example) CW clockwise rotation, the spiral surface 74 along the pin 75 being moved so that the pin 75 contacts the ramp section, and contacts the first pause portion 74b '. 然后,当轴70再次顺时针CW旋转时,该销可以接触第二停顿部分74b' '。 Then, when the shaft 70 clockwise CW rotation again, the pin may contact the second pause portion 74b ''. 之后,轴70按顺时针CW方向继续旋转可使该销接触第三停顿部分74b' ''。 Thereafter, the shaft 70 continues to rotate in a clockwise direction CW can pause the pin contacting third portion 74b '' '. 如下面将进行的更详细的说明,每个停顿部分可以相对于斜坡部分74a处于不同角度构造处。 A more detailed description will be made as below, with respect to each of them to be part of the slope portion 74a is constructed at different angles.

[0055] 此外,每个停顿部分74b'、74b' '和74b' ''可位于沿砧座调节轴70的不同纵向位置处,以提供预定的分立缝钉成形高度。 [0055] In addition, each of them to part 74b ', 74b' 'and 74b' '' may be located along the anvil longitudinal adjustment shaft 70 at different locations to provide a predetermined discrete staple forming height. 例如,参见图10A,第一停顿部分74b'可位于距轴组件的横向凸缘77为第一距离。 For example, referring to Figure 1OA, the first halt portion 74b 'may be positioned laterally from the axis of the flange assembly 77 a first distance. 处。 Place. 第二停顿部分74b''可位于距横向凸缘77第二距离。 Second pause portion 74b '' may be located at a second distance from the lateral flange 77. 处,而第三停顿部分74b' ''可位于距横向凸缘77第三距离L3处。 At a standstill while the third section 74b '' 'may be located away from the lateral flange 77 at a third distance L3. 包括横向凸缘77的任何参考点或参考平面可用于建立上述距离。 Including horizontal flange 77 of any reference point or reference plane can be used to establish the distance. 在任何情况下,第一距离U可以大于第二距离L2,第二距离可以大于第三距离L3,或者LOL0L3。 In any case, the first distance may be greater than the second distance U L2, the third distance may be greater than the second distance L3, or LOL0L3. 作为另外一种选择,尽管图中未示出,然而这些距离可为其他比较次序,例如LOL0L2,L0LOL3,LALALi,LALALi,或者L0LOL2。 Alternatively, although not shown, however, these distances may be other sequence comparison, e.g. LOL0L2, L0LOL3, LALALi, LALALi, or L0LOL2. 此外,在相应停顿部分74b '、74b ' '和74b ' ' '上的各停顿距离U、LdPL3可以是均匀的。 Moreover, the portion corresponding pause 74b ', 74b' 'and 74b' 'from each pause U' on, LdPL3 may be uniform. 换句话讲,例如参见图10B,在螺旋表面的斜坡部分74a可相对于调节轴的纵向轴线L以小于90度的斜坡或螺旋角α倾斜的同时,每一停顿部分(例如图10B中的74b'')可基本上垂直于纵向轴线L,或者相对于轴线L限定近似90度的夹角Θ。 In other words, for example, see FIG. 10B, the spiral ramp surface portion 74a with respect to the longitudinal axis L of less than 90 degrees with the slope or helix angle of inclination α while the adjustment shaft, each of the pause portion (e.g., Fig. 10B 74b '') may be substantially perpendicular to the longitudinal axis L, or with respect to the axis L defines an angle of approximately 90 degrees Θ. 此外,参见图9和图10A-10C,停顿部分74b'、74b'、74b''' 也可为用于限定预定的分立缝钉高度的台阶,如下文所述。 Further, referring to FIG. 9 and FIG. 10A-10C, a pause portion 74b ', 74b', 74b '' 'may also be used to define a predetermined discrete steps, staple height, as described below. 当测量相对于纵向轴线L的上述角度时,应当理解,此类测量可以相对于这样的平面进行:该平面与螺旋表面74的一部分以及该平面与纵向轴线L相交的点相切,为了清晰起见,纵向轴线L沿图10A-10C中所示砧座调节轴的整个长度显示。 When measuring the angle with respect to the longitudinal axis L, it should be appreciated that such measurements can be made with respect to a plane: a portion of the plane with the helical surface 74 and the tangent point of the plane intersecting the longitudinal axis L, for clarity , along the longitudinal axis L of the anvil entire length adjuster shaft 10A-10C show in FIG. 例如,再次参见图10B,螺旋角度α在切平面"TP"和纵向轴线L之间限定,其中该切平面垂直于图10Β所在的纸面平面。 For example, referring again to FIG. 10B, the helix angle α defined between the tangent plane "TP" and the longitudinal axis L, wherein the tangent plane perpendicular to the plane of the paper in FIG 10Β located.

[0056]现在关注图11Α-11C,缝合头30和砧座50显示处于与轴的螺旋表面的停顿部分74b'、74b''和74b'' '相关联的多个位置。 [0056] Attention is now FIG 11Α-11C, the suture head 30 and the anvil 50 is displayed at a standstill and the spiral portion of the shaft surface 74b ', 74b' 'and 74b' '' associated with multiple locations. 例如,分立的缝钉成形高度可以限定于砧座50的缝钉成形表面51和钉仓33的缝钉弹出表面38之间。 For example, discrete staple forming height can be limited to one of the anvil staple forming surface 50 of staple cartridge 51 and 33 between surfaces 38 pop. 第一高度Di可以大于第二高度D2,第二高度可以大于第三高度D3,或者DOD0D3。 Di first height may be greater than the second height D2, the second height may be greater than the third height D3, or DOD0D3. 同时参见图10A-10C和11A-11C,在旋转调节轴70的同时,每个停顿部分74b'、74b' '和/或74b' ''可允许砧座50保持在相应的缝钉成形高度D^DjP/或D3处,使得停顿部分沿销75运动(参见图5)。 See also FIG. 10A-10C and 11A-11C, the rotary shaft 70 while adjusting, at each of them portion 74b ', 74b' 'and / or 74b' '' can allow anvil 50 held in the respective staple forming height D ^ DjP / or D3 at a standstill so that the pin 75 along part motion (see Figure 5). 例如,每个停顿部分74b'、 74b''、74b'''可设计成在轴旋转约60度的时间段内保持砧座的位置。 For example, each of them to part 74b ', 74b' ', 74b' '' may be designed to rotate the shaft about 60 degrees anvil position holding period. 换句话讲,沿每个停顿部分的表面延伸的弧可以在大约60度的角度范围内延伸。 In other words, it may extend along an arc extending surface portion of each pause in the angular range of approximately 60 degrees.

[0057] 参见图9和10A-10C,在多个实施例中,至少一个过渡部可以分开每个停顿部分74b'、74b' '和/或74b' '',从而使得砧座调节轴70能够相对于销75前进到另一个位置(参见图5)。 [0057] Referring to Figures 9 and 10A-10C, in various embodiments, at least a portion may be separated from each of them to transition portion 74b ', 74b' 'and / or 74b' '', so that the anvil shaft 70 can be adjusted relative to the pin 75 proceeds to another position (see FIG. 5). 在至少一个实施例中,过渡部可包括另一个斜坡部分和/或部分螺旋表面。 In at least one embodiment, the transition portion may further include a ramp portion and / or the surface of the spiral portion. 然而,在至少一个其他实施例中,过渡部也可包括至少一个限定器。 However, at least one other embodiments, the transition portion may include at least one qualifier. 如图10A-10C中可见,第一限定器76 '可将螺旋表面的斜坡部分74a与第一停顿部分74b '分开,第二限定器76 ''可将第一停顿部分74b'与第二停顿部分74b' '分开,第三限定器76' ''可将第二停顿部分74b' '与第三停顿部分74b' ''分开。 FIG. 10A-10C can be seen, the first qualifier 76 'may be part of the spiral ramp surface 74a of the first pause portion 74b' separated from the second qualifier 76 '' may be the first halt portion 74b 'and the second pause part 74b '' separated from the third limiter 76 '' 'may be a second pause portion 74b' and the third halt portion 74b '' 'to separate. 如上所述,每个限定器76'、76' '和/或76' ''可在使用者旋转砧座调节轴的同时向使用者提供触觉反馈。 As described above, each defining 76 ', 76' 'and / or 76' '' in the user rotates the anvil adjustment shaft while providing tactile feedback to the user.

[0058] 更具体地,再次参见图9和10A-10C,每个限定器76'、76' '和/或76' ' '可包括位于螺旋表面中的凸耳或突起。 [0058] More specifically, again see FIG. 9 and 10A-10C, each restrictor 76 ', 76' 'and / or 76' '' may include a helical surface projections or lugs. 换句话讲,螺旋表面74可限定包括斜坡部分74a与停顿部分74b'、74b' '和74b' ' '的表面形貌,并且每个限定器76'、76' '和/或76' ' '可以是分别位于上述部分之间的表面形貌中的中断部。 In other words, the helical surface 74 may include a ramp portion 74a and define a pause portion 74b ', 74b' 'and 74b' '' of the surface topography, and each qualifier 76 ', 76' 'and / or 76' ' 'may be located between said portion of the surface topography of the interruptions. 另外,除了限定器76'、76''和/或76'''之外,位于螺旋表面74的任何部分上的表面形貌都可以是平滑的。 In addition to defining 76 ', 76' outside 'and / or 76' '', any part of the surface topography of the surface 74 are located on a spiral may be smooth. 例如,参见图5、9和10A-10C,螺旋表面的斜坡部分74a可包括平滑形貌,使得当砧座调节轴70相对于主体10旋转时,螺旋表面74可以相对平滑地运动经过销75。 See, e.g., FIG. 5, 9 and 10A-10C, the helical slope portion 74a may include a smooth surface topography, such that when the anvil adjustment shaft 10 is rotated relative to the body 70, the coil 74 can be relatively smoothly while the surface moves past the pin 75. 然而,当销75到达斜坡部分74a的末端时,表面形貌可以被第一限定器76 '中断。 However, when the pin 75 reaches the end of the ramp portion 74a, the surface topography can be defined in the first 76 'interrupt. 因此,当螺旋表面74在销75上方前进,伴随第一限定器76 '接触销75(这归因于螺旋表面74的表面形貌在限定器76'处的中断),调节轴70(当轴70旋转时,其可以由近端以平滑的方式从主体10中延伸)可以不连贯或不连续的方式跳动、推动或拉动,或以其他方式向使用者提供触觉反馈。 Therefore, when the helical surface 74 above the pin 75 in advance, with the first limited to 76 'of the contact pins 75 (due to the surface topography of the helical surface 74 of the limiter 76' interrupt), the adjustment shaft 70 (the shaft 70 rotating, which can smooth the way from the main body extending from a proximal end 10) may not be consistent or discontinuous fashion beat, push or pull, or otherwise provide tactile feedback to the user. 第一限定器76'在销75上方经过的动作可以向对轴70进行旋转的使用者提示销75此时已容纳在第一停顿部分74b'处,因而第一分立的缝钉成形高度Di (参见图11A)已达到。 A first limiter 76 'at the top of the pin 75 through the action of the shaft 70 may rotate the pin 75 prompts the user has received in this case the first pause portion 74b' at, so that the first discrete staple forming heights Di ( Referring to FIG. 11A) has been reached. 轴70在停顿期(如上所述,可以为大约60度)内的连续旋转可并不调节第一缝钉成形高度Di。 Continuous rotation of shaft 70 in the standstill period (as described above, may be about 60 degrees) can not be adjusted within the first staple forming height Di. 因此,使用者不一定需要关注砧座调节轴70所处的准确旋转位置,只要使用者知道第一缝钉成形高度D!在轴70被进一步旋转以使另一个限定器接触销75之前将不会改变即可。 Thus, the user does not necessarily need to focus accurately adjust the rotational position of the anvil shaft 70 which, as long as the user knows the first staple forming height of the D! Shaft 70 is further rotated so that another qualifier before the contact pins 75 will not It will change to. 此外,使用者可以来回旋转砧座调节轴70,使得销75沿着第一停顿部分74b'在第一限定器76'和第二限定器76''之间相对运动。 In addition, the user can rotate back and forth to adjust the anvil shaft 70, so that the pin 75 along the first halt portion 74b 76 'relative movement between the' 'defined in the first 76' and the second qualifier. 因为限定器从第一停顿部分74b' 的表面突出,当销75接触位于第一停顿部分74b'相应末端处的第一限定器76'或第二限定器76''时,使用者通过砧座调节轴70可以感觉到,从而让使用者确信已经到达第一缝钉成形高度Du Because from the first pause defining portion 74b 'projecting surface, when the contact pin 75 in the first halt portion 74b' corresponding to the first qualifier at the end of 76 'or the second restrictor 76' ', the user through the anvil adjusting shaft 70 may feel, so that users believe has reached the first staple forming height Du

[0059] 参见图5、9和10A-10C,如果使用者希望将缝钉成形高度从第一缝钉成形高度0:改变为第二缝钉成形高度D2(参见图11A-11B),则使用者可以进一步旋转砧座调节轴70,使得第二限定器76''接触销75。 [0059] Referring to Fig. 5, 9 and 10A-10C, if the user wishes to staple forming height forming a first staple height from 0: to a second staple forming height D2 (see FIG. 11A-11B), use may further rotate anvil adjustment shaft 70, so that the second delimiter 76 'of the contact pin 75. 当销75到达第一停顿部分74b'的末端时,表面形貌可被第二限定器76''中断。 When the pin 75 reaches the first pause portion 74b 'at the end, the surface topography can be defined in the second 76' 'Delay. 因此,当螺旋表面74在销75上方前进时,伴随第二限定器76''接触销75(这归因于螺旋表面74的表面形貌在限定器76'''处的中断),调节轴70(在销75接触第一停顿部分74b'期间,其可以平滑地旋转)可以不连贯或不连续的方式跳动、推动或拉动,或以其他方式向使用者提供触觉反馈。 Therefore, when the screw top surface 74 of the pin 75 is advanced, with the second qualifier 76 '' of the contact pins 75 (due to the helical surface topography of the surface 74 of the limiter 76 'interrupt' 'Department), the adjusting shaft 70 (pin 75 in contact with the first pause portion 74b 'period, which can be smoothly rotated) may not be consistent or discontinuous fashion beat, push or pull, or otherwise provide tactile feedback to the user. 第二限定器76''在销75上方经过的动作可以向旋转轴70的使用者提示销75此时已容纳在第二停顿部分74b''处,因而第二分立的缝钉成形高度D2(参见图11B)已达到。 Defining a second 76 '' at the top of the pin 75 through the operation of the user may be prompted to the rotary shaft 70 of the pin 75 is housed in the second case portion 74b pause 'point, so that the second staple forming height discrete D2 ( see FIG. 11B) has been reached. 轴70在停顿期(如上所述,可以为大约60度)内的连续旋转可并不调节第二缝钉成形高度D2。 Shaft 70 in the standstill period (as described above, may be about 60 degrees) within the continuous rotation can not adjust the second staple forming height D2. 因此,使用者不一定需要关注砧座调节轴70所处的准确旋转位置,只要使用者知道第二缝钉成形高度〇2在轴70被进一步旋转以使另一个限定器接触销75之前将不会改变即可。 Thus, the user does not necessarily need to focus accurately adjust the rotational position of the anvil shaft 70 which, as long as the user knows that the second staple forming height 〇2 shaft 70 is further rotated to define another device before the contact pins 75 will not It will change to. 此外,使用者可以来回旋转砧座调节轴70,使得销75沿着第二停顿部分74b' '在第二限定器76' '和第三限定器76' ''之间相对运动。 In addition, the user can rotate back and forth to adjust the anvil shaft 70, so that the pin 75 along the second Pause portion 74b '76' relative motion between '' in the second limited 76 '' and the third qualifier '. 随着限定器从第二停顿部分74b' '的表面突出,使用者通过砧座调节轴70可以感觉到销75何时接触位于第二停顿部分74b' '相应末端处的第二限定器76' '或第三限定器76' '',从而让使用者确信已经到达第二缝钉成形高度D2。 With the qualifier from the second portion standstill 74b '' protruding surface, the user adjusts the anvil shaft 70 by a pin 75 can be felt when touching a halt in the second portion 74b '' corresponding to the second qualifier at the end of 76 ' 'or the third limiter 76' '', thereby allowing users to believe they have reached the second staple forming height D2.

[0060] 相似地,仍然参见图5、9和10A-10C,如果使用者希望将缝钉成形高度从第二缝钉成形高度〇2改变为第三缝钉成形高度D3(参见图11B-11C),则使用者可以进一步旋转砧座调节轴70,从而使第三限定器76' ''接触销75。 [0060] Similarly, still to Figure 5, 9 and 10A-10C, if the user wishes to staple forming height is changed from the second forming height of the staples 〇2 third staple forming height D3 (see FIG. 11B-11C ), the user can further adjust the rotating anvil shaft 70, so that the third restrictor 76 '' 'of the contact pins 75. 当销75到达第二停顿部分74b' '的末端时,表面形貌可以被第三限定器76'''中断。 When the pin 75 reaches the second pause portion 74b '' at the end, the surface topography can be defined in a third 76 '' Delay. 因此,当螺旋表面74在销75上方前进时,伴随第三限定器76' ''接触销75(这归因于螺旋表面74的表面形貌在限定器76' ''处的中断),调节轴70 (在销75接触第二停顿部分74b''的同时,其可以平滑地旋转)可以不连贯或不连续的方式跳动、推动或拉动,或以其他方式向使用者提供触觉反馈。 Therefore, when the screw top surface 74 of the pin 75 is advanced, with the third qualifier 76 '' 'of the contact pins 75 (due to the surface topography of the helical surface 74 of the limiter 76' interrupt '' at), adjust shaft 70 (pin 75 while in contact with the second portion pause 74b '', which can be smoothly rotated) may not be consistent or discontinuous fashion beat, push or pull, or otherwise provide tactile feedback to the user. 第三限定器76' ''在销75上方经过的动作可以向对轴70进行旋转的使用者提供指示,以提示销75此时已容纳在第三停顿部分74b'''处,因而第三分立的缝钉成形高度D3(参见图11C)已达到。 The third qualifier 76 '' 'at the top of the pin 75 through the action of the shaft 70 may be rotated to the user with an indication, this time to prompt the pin 75 is housed in the third pause part 74b' '' place, so the third discrete staple forming height D3 (see FIG. 11C) has been reached. 轴70在停顿期(如上所述,可以为大约60度)内的连续旋转可并不调节第三缝钉成形高度D3。 Shaft 70 in the standstill period (as described above, may be about 60 degrees) within the continuous rotation can not adjust the third staple forming height D3. 因此,使用者不一定需要关注砧座调节轴70所处的准确旋转位置,只要使用者知道第三缝钉成形高度D3在轴70 被进一步旋转以使阻挡件78接触销75、从而防止销75相对于螺旋表面74朝阻挡件78进一步运动之前将不会改变即可。 Thus, the user does not necessarily need to focus accurately adjust the rotational position of the anvil shaft 70 which, as long as the user knows the third staple forming height D3 of the shaft 70 is further rotated to move the barrier member 78 of the contact pins 75, thereby preventing the pin 75 with respect to the spiral surface 74 toward the barrier 78 before further movement will not be changed. 阻挡件78可以是形成在第三限定器部分74b' ''末端处的壁。 Blocking member 78 may be formed in the third portion defining 74b '' 'at the end of the wall. 此外,使用者可以来回旋转砧座调节轴70,使得销75沿着第三停顿部分74b' ''在第三限定器76' ''和阻挡件78之间相对运动。 In addition, the user can rotate back and forth to adjust the anvil shaft 70, so that the pin 75 along the third pause part 74b '' '76 in the third qualifier' '' and the relative movement between the 78 barrier. 因为阻挡件和限定器76' ''从第三停顿部分74b' '的表面突出,当销75接触位于第三停顿部分74b' ''相应末端处的第三限定器76' ''或阻挡件78时, 使用者通过砧座调节轴70可以感觉到,从而让使用者确信已经到达第三缝钉成形高度D3。 Because the dam and defining 76 '' 'from the third part of a standstill 74b' surface 'is prominent, when the contact pin 75 in the third pause part 74b' '' third qualifier at the respective ends 76 '' 'or barrier 78, a user by adjusting the anvil shaft 70 can feel confident that we have so that the user reaches the third staple forming height D3. [0061 ] 在多个实施例中,参见图9和15,例如,螺旋表面74可以在斜坡部分74a闭合,而在停顿部分74b '、74b ''、74b '''打开。 [0061] In various embodiments, referring to Figs 9 and 15, e.g., the surface of the coil 74 can be closed at the slope portion 74a, and the dwell portion 74b ', 74b' ', 74b' '' to open. 换句话讲,螺旋表面的斜坡部分可包括近端壁和远端壁,而螺旋表面的停顿部分可仅包括近端壁。 In other words, part of the spiral ramp surface may include a proximal wall and a distal wall, and halt the spiral portion may include only the surface of the proximal end of a wall. 在使用中,销75可受偏压抵靠停顿部分,这是由于当砧座50位于距离头部30合适的缝钉成形高度处时,组织被夹在砧座50和缝合头30之间,如上面所讨论(参见图11A-11C)。 In use, the pin 75 may be biased against the pause part, this is because when the anvil 50 is located at a suitable distance from the head 30 of the staple forming height, tissue is clamped between the anvil 50 and the stapling head 30, as discussed above (see FIG. 11A-11C).

[0062] 虽然以上所述至少一个实施例示出限定器76'、76' '和/或76' ''成形为螺旋表面74中的凸耳或突起,但限定器也可以采用位于螺旋表面中的缺口的形式。 [0062] Although the above at least one embodiment illustrates restrictor 76 ', 76' 'and / or 76' '' shaped as a helical surface 74 of the lug or projection, but the qualifier may be used located helical surfaces form gap. 另外,限定器可以是与调节轴70分开的部件,使得它们可以附接到调节轴70。 Further, the qualifier may be adjusted with a separate shaft member 70, so that they may be attached to the adjusting shaft 70. 在任何情况下,当使用者旋转轴70时,限定器可以向使用者提供触觉反馈。 In any case, when the user rotates the shaft 70, the qualifier can provide tactile feedback to the user. 此外,虽然限定器显示为将斜坡部分74a与第一停顿部分74b'等分开,但螺旋表面可以不包括一个或多个停顿部分。 In addition, although the slope is defined as the display portion 74a of the first pause portion 74b 'etc. to separate, but the helical surface may not include one or more portions pause. 在此类实施例中,螺旋表面可包括被至少一个限定器以所需间隔分开的多个斜坡部分。 In such embodiments, the helical surface may comprise at least one filter defining a plurality of spaced-apart desired slope portion. 因此,当砧座50和钉仓33 之间(参见例如图11A)已经获得合适的缝钉成形高度时,使用者可以通过触觉反馈获知。 Therefore, when the anvil 50 and staple cartridge 33 between (for example, see FIG. 11A) has received appropriate staple height during molding, the user can learn through tactile feedback.

[0063] 除了触觉反馈之外,外科缝合器1可包括可视参考标记,用以在达到缝钉成形高度时向使用者提示。 [0063] In addition to the tactile feedback, a surgical stapling instrument 1 may include a visual reference mark to prompt the user to the staple forming height is reached. 例如,现在参见图12-13,砧座调节轴70可包括印刷或成形在轴表面上的参考标记85,该参考标记通过主体10上的标志86而在已达到诸如Di、D2、D3(参见图11A-11C) 的分立缝钉成形高度时,提供相应指示。 For example, Referring now to Figures 12-13, anvil adjustment shaft 70 may include a printed or formed on the surface of the shaft 85 of the reference marks, which reference marks by mark 86 on the body 10 has been reached, such as in Di, D2, D3 (see Figure 11A-11C) when the discrete staple forming height, to provide the corresponding indication. 在至少一个实施例中,相应的缝钉成形高度可以是2.5mm、l.8mm和1.0mm,并且参考标记85可以指示这些高度。 In at least one embodiment, the corresponding staple forming height can be 2.5mm, l.8mm and 1.0mm, and reference numeral 85 may indicate the height. 在任何情况下,将如上面所讨论的可视标记、限定器和/或停顿部分结合到砧座调节轴70中,可以不再需要与轴分开的缝钉高度指示机构。 In any case, the visual indicia as discussed above, defining and / or pause portion bonded to the anvil adjustment shaft 70, may no longer need to separate from the shafts staple height indicator means.

[0064]另外,虽然以上所述至少一个实施例已经将螺旋表面74示出为由形成于砧座调节轴70中的槽限定,但作为另外一种选择,在至少一个实施例中,螺旋表面可由从砧座调节轴70突出的螺纹限定。 [0064] Further, although the above embodiment has at least one surface of the coil 74 shown is formed by adjusting the anvil shaft 70 defining the groove, but alternatively, at least one embodiment, the spiral surface by adjusting the screw shaft 70 projecting from defining anvil. 在此类实施例中,可以采用销75,或者可以使用另一个螺纹配合部件来啮合螺旋表面,例如,从主体10内部伸出的叉状物。 In such embodiments, the pin 75 may be used, or you can use another member to engage the screw threads mating surface, for example, from the inner body 10 extending prongs.

[0065]此外,虽然上面讨论的螺旋表面74被描述作为砧座调节轴70的一部分,但应当理解,作为另外一种选择,这样的螺旋表面可作为主体10的一部分。 [0065] In addition, although the helical surface 74 as discussed above is described as part of the regulatory anvil shaft 70, it should be understood that, alternatively, such as the helical surface 10 of the body part. 在此类实施例中,诸如销或其他螺纹配合部件的接合部将同样被固定到调节轴70,而不是固定到主体10。 In such embodiments, such as a pin or other engagement with the threaded member will also be fixed to the adjustment shaft 70, rather than being fixed to the body 10. 在任何情况下,轴70的旋转可使螺旋表面相对于接合部旋转,使得轴70,继而砧座50相对于主体10 和/或缝合头30平移。 In any case, the rotary shaft 70 can rotate the helical surface relative to the engaging portion, such that the shaft 70, and then the anvil 50 relative to the body 10 and / or the stapling head 30 pan.

[0066] 在多个实施例中,如上面所提及并参见图5,在砧座50处于离钉仓33适当距离处之前,触发器90可与调节轴70配合,以防止触发器90实质上朝主体10运动,或换句话说,防止导致缝钉驱动器34和/或切割构件32被启动,从而防止外科缝合器1的意外击发。 [0066] In various embodiments, as mentioned above, and with reference to FIG. 5, the anvil 50 is from before the cartridge 33 at a suitable distance, the trigger 90 can be adjusted with the shaft 70 cooperate to prevent the trigger from 90 essence 10 movement towards the body, or in other words, to prevent the cause staple driver 34 and / or cutting member 32 is activated, thereby preventing accidental surgical stapler 1 firing. 换句话讲, 触发器可包括锁定器。 In other words, the trigger may include a locking device. 例如,在至少一个实施例中并参见图8,致动轴70可包括限定第一宽度Wi的第一近端部分70a和限定第二宽度%的第二远端部分70b。 For example, at least one embodiment and with reference to FIG. 8, the actuating shaft 70 may include a first width Wi defining a first proximal end portion 70a and the second width defining a second distal portion% 70b. 此外,参见图14,触发器90 可包括从杠杆92延伸的锁定杆95,杆95限定开口97,开口97的尺寸为S。 Further, referring to Figure 14, the trigger 90 may include a locking lever 95 extends from the lever 92, the rod 95 defines an opening 97, the size of the opening 97 is S. 锁定杆可类似于具有两个尖头的叉或者类似于托架。 Lock lever may be similar to having two prongs of the fork or similar bracket. 在任何情况下,开口97的尺寸S可小于近端部分70a的第一宽度W!,但开口97的尺寸S可大于或等于远端部分70b的第二宽度W2,或者Wi>S 2 W2。 In any case, the opening 97 may be smaller than the size S of the width W of the first proximal end portion 70a of the opening 97 !, but the dimension S may be greater than or equal to the second distal end portion 70b of the width W2 or Wi> S 2 W2.

[0067]现在参见图15,锁定杆95可以被布置成通过主体开口14,使得杆95可操作以接合轴的近端部分70a或者轴的远端部分70b。 [0067] Referring now to FIG. 15, the lock lever 95 may be arranged through the body opening 14, such that the rod 95 is operable to engage the distal end of the shaft or proximal portion 70a of the shaft portion 70b. 如果锁定杆95纵向地被布置在近端部分70a上方, 则触发杠杆92会由于锁定杆95和轴的近端部分70a之间的干扰作用而被阻止实质上朝主体10运动。 If the lock lever 95 is disposed longitudinally above the proximal end portion 70a, the lever 92 is triggered due to interference of the locking lever 95 between the portion 70a and the proximal end of the shaft is substantially prevented toward the main body 10 is moved. 换句话讲,由于近端部分的宽度1(参见图8)大于锁定杆开口97的尺寸S(参见图14),可以防止触发杠杆92引起驱动带80启动,如上面所述,从而防止缝钉31和/或切割构件32意外击发(参见图3)。 In other words, since the width of the proximal portion 1 (see FIG. 8) is larger than the opening 97 of the locking lever dimension S (see FIG. 14), the trigger lever 92 can be prevented from causing drive belt 80 to start, as described above, thereby preventing slot 31 nails and / or cutting member 32 accidental firing (see Figure 3). 然而,如果锁定杆95纵向地被布置在远端部分70b上方,则触发杠杆92会由于锁定杆95和轴的远端部分70b之间没有干涉作用而被允许实质上朝主体10运动。 However, if the lock lever 95 is disposed longitudinally above the distal end portion 70b, the trigger lever 92 due to no interference effect between the locking lever 95 and the distal end portion 70b of the shaft 10 is allowed to substantially toward the moving subject. 换句话讲,由于远端部分的宽度W2(参见图8)小于或等于锁定杆的开口97的尺寸S(参见图14),可以允许触发杠杆92运动并导致驱动带80启动,如上面所述,从而击发缝钉31和/或切割构件32(参见图3)。 In other words, since the distal end portion of the width W2 (see FIG. 8) is less than or equal to the size S of the locking lever opening 97 (see FIG. 14), it may allow movement of the trigger 92 and lever 80 causes the drive to start with, as above above, thereby firing the staples 31 and / or the cutting member 32 (see FIG. 3). 在此类实施例中,开口97可容纳轴的远端部分70b并允许杠杆92朝主体10运动,直到远端部分70b到达开口97的末端。 In such embodiments, the opening 97 can accommodate the distal end portion 70b of the shaft 92 and allow the lever 10 is moved toward the body, until the distal end portion 70b reaches the opening 97.

[0068] 此外,参见图15,轴的远端部分70b可以沿砧座调节轴70定位,使得远端部分70b与合适的缝钉成形高度相关联。 [0068] In addition, referring to Figure 15, the distal end portion of the shaft 70b can be adjusted along the axis of the anvil 70 is positioned such that the distal end portion 70b with a suitable staple forming height associated. 例如,远端部分70b可以沿轴70轴向布置,使得当销75被容纳在停顿部分(例如第一停顿部分74b')中时,锁定杆95纵向地布置在远端部分70b上方。 For example, the distal portion 70b may be disposed axially along the shaft 70, such that when the pin 75 is received in the pause portion (e.g., the first halt portion 74b '), the latching lever 95 disposed longitudinally above the distal end portion 70b. 因此,锁定杆95可以在已达到所需缝钉成形高度时仅允许缝钉驱动器34和/或切割构件32(参见图3)被击发,而不需要与触发器90分开的锁定杠杆或机构。 Thus, the locking lever 95 has been reached may allow the desired staple forming height only staple driver 34 and / or the cutting member 32 (see FIG. 3) is fired, the trigger 90 without the need for a separate mechanism or the lock lever. 此外,参见图14,锁定杆95可以由与触发器弹簧91相同的同一块材料一体和整体地形成。 Further, referring to Figure 14, the locking lever 95 can be integrally formed from and integrally with the trigger spring 91 with a same material. 然而,在至少一个实施例中,锁定杆95、触发器弹簧91和杠杆92可以由同一块材料一体和整体地形成。 However, in at least one embodiment, the lock lever 95, spring 91 and trigger lever 92 may be formed integrally from the same piece of material and integrally.

[0069] 在多个实施例中,并且如上面所提及,外科缝合器可以是直的,而不是如上所述弯曲的。 [0069] In various embodiments, and as mentioned above, a surgical stapling instrument can be straight, rather than curved as described above. 因此,现在参见图16,其中示出了一种外科缝合器101。 Thus, now to Figure 16, there is shown a surgical stapling device 101. 外科缝合器101可包括类似于上面所述的主体110、缝合头130、砧座150、砧座调节轴170和触发器190。 Surgical stapler 101 may include a body similar to that described above 110, the suture head 130, an anvil 150 anvil adjustment shaft 170 and the flip-flop 190. 然而,主体110的轴部112可以是直的。 However, the shaft portion 112 of the body 110 may be straight. 此外,缝合头130和砧座150可以是线性的,并且远离主体110轴向地伸出。 In addition, the suture head 130 and the anvil 150 may be linear, and away from the body 110 projects axially. 应该指出的是,参见图1和16中分别示出的外科缝合器1和外科缝合器101,由于各缝合头30、缝合头130如上所述可从外科缝合器主体10、外科缝合器主体110移除,缝合头30、缝合头130和砧座50、砧座150可以例如彼此互换。 It should be noted, and refer to FIG. 16 show a surgical stapler and a surgical stapling device 101, since the head 30 of each suture, the suture head 130 described above from the body 10 of the surgical stapler, the surgical stapler body 110 remove, suture head 30, the suture head 130 and the anvil 50, anvil 150 can be interchanged with one another, for example. 除了上述头部30、头部130和砧座50、砧座150之外,还可以采用其他缝合头构造和砧座构造。 In addition to the head 30, the head 130 and the anvil 50, anvil 150 can also be configured to use other stapling head and the anvil structure.

[0070] 另外,现在参见图17,砧座调节轴170和套管针173可以由同一块材料一体和整体地形成。 [0070] Further, Referring now to Figure 17, the anvil 170 and the adjustment shaft and the trocar 173 may be integrally formed from the same piece of material integrally. 因此,轴的远端部分170b可从近端部分170a伸出并邻接套管针173。 Therefore, the distal end portion of the shaft 170b may protrude from the proximal end portion 170a and adjacent to the trocar 173. 此外,参见图18,其中示出了驱动杆180。 Further, referring to Figure 18, there is shown a drive rod 180. 驱动杆可允许触发器190(参见图16)运动以朝缝合头130启动驱动杆180,以从中弹出缝钉和/或启动切割构件(未示出)。 Drive lever allows trigger 190 (see Fig. 16) movement towards the suture head 130 to start the drive rod 180 to eject staples therefrom and / or start cutting member (not shown). 简而言之,驱动杆可以是细长的通常为管状的形状,并且包括近端驱动表面181和远端驱动表面182。 In short, the drive rod may be elongated generally tubular shape and includes a proximal end 181 and a distal driving surface 182 drive surface. 参见图16和18,近端驱动表面181能够容纳来自触发器190的驱动,而远端驱动表面182能够在缝合头130内接合缝钉驱动器和/或切割构件(未示出),如上所述。 Referring to Figure 16 and 18, the proximal end of the drive surface 181 to accommodate the drive from the flip-flop 190, while the distal driving surface 182 configured to engage staple driver and / or cutting member within stapling head 130 (not shown), as described above . 另外,驱动杆180可包括通道187,该通道能够容纳穿过其中的砧座调节轴170(参见图17)。 Additionally, the drive rod 180 may include a passageway 187, to accommodate the passage therethrough of the anvil adjustment shaft 170 (see FIG. 17). 在至少一个实施例中,缝合器101可以不包括切割构件,并且可以主要用来缝合或密封组织,而不是横切组织。 In at least one embodiment, the suturing device 101 may not include a cutting member, and may be primarily used for stitching or sealing tissue, rather than transverse tissue.

[0071] 应当理解,以上讨论的直缝合器101和弯曲缝合器1(分别参见图16和图1)可包含比市场上可获得的类似现有外科缝合器明显更少的部件。 [0071] It should be appreciated that the linear stapler 101 as discussed above, and a curved suturing device 1 (see FIG. 1 and FIG. 16, respectively) may comprise more than similar conventional commercially available surgical stapler significantly fewer components. 例如,参见直外科缝合器101,特别是参见砧座调节轴,将旋钮179与闭合螺钉或螺旋表面174以及套管针173组合成一个整体部件砧座调节轴170减少了外科缝合器的部件数。 See, e.g., linear surgical stapler 101, see especially anvil adjustment shaft, the knob 179 and the closing screw or helical surface 174 and trocar 173 combination as an integral part of the anvil shaft 170 adjustment reduces the number of components of a surgical stapler . 通过将斜坡部分174a与停顿部分174b 组合成螺旋表面174,可进一步减少部件数。 By the slope portion 174a and 174b are combined into a pause helical surface portion 174, the number of parts can be further reduced. 如上面所讨论,螺旋表面的斜坡部分174a可允许轴170相对于主体110的初始快速轴向运动,而停顿部分174b可以在砧座150和缝合头130 之间建立至少一个分立的预定缝钉成形高度。 As discussed above, the surface of the spiral ramp portion 174a allows the shaft 170 with respect to the initial rapid axial movement of the body 110, and a pause portion 174b can establish at least one predetermined discrete staple between the anvil 150 and stapling head 130 forming height. 总体上,忽略砧座和缝合头部件,相比现有装置中三十个以上的部件,外科缝合器101可以仅包括七个部件。 In general, ignoring the anvil and stapling head assembly, as compared to the conventional apparatus, thirty or more members, a surgical stapling instrument 101 may include only seven members. 参见图16-18,这七个部件可包括主体110、击发触发器190、将触发器190可枢转地联接到主体110的铰链销193、与锁定杆195-体形成的触发器弹簧191、砧座调节轴170、可操作地接合轴的螺旋表面174的螺销(未示出,参见例如图3所示的螺销75)以及驱动杆180。 Referring to Figure 16-18, the seven member may include a body 110, firing trigger 190, the trigger 190 is pivotally coupled to the hinge pin 193 of the body 110, and a spring trigger the locking lever is formed 191195-, adjusting the anvil shaft 170, the shaft operably engaged helical surface 174 of the pin screw (not shown, see e.g., FIG. 3 spiral pin 75 shown) and a drive lever 180. 另外,可以进一步减少部件数。 Further, the number of parts can be further reduced. 例如, 通过将例如铰链止动装置或柔性接片组合到触发器190自身中,即可以取消铰链销193。 For example, by means such as a hinge or a flexible stop lugs 190 to a flip composition itself, i.e., hinge pin 193 can be canceled. 此外,弹簧191和锁定杆195也可与触发器190-体形成。 In addition, the spring 191 and the locking lever 195 may be formed with the trigger 190- body. 另外,通过加入从主体110内表面延伸的突起,使得螺旋突起可以接合螺旋表面174,从而可以取消螺销(未示出)。 Further, by adding the protrusions 110 extending from the inner surface of the main body, so that the projection may engage the helical spiral surface 174, which can cancel the screw pin (not shown). 在任何情况下, 外科缝合器101的前述部件可以提供与上面所述类似的功能。 In any case, the aforementioned surgical stapling member 101 may provide functionality similar to that described above. 这种仅使用少许制造技术的简化的缝合器结构可以广泛地应用,并应适用于多用途可消毒装置,该装置相比类似的目前可用的外科缝合器成本明显更低,并且所需制造时间更少。 This use of only a few of the manufacturing techniques of suturing simplified structure can be widely used, and can be applied to a multi-purpose disinfecting apparatus compared to similar currently available surgical stapler significantly lower the cost of, and time required to manufacture less. 因此,在至少一个实施例中, 可以提供包括上述部件而减少砧座和缝合头部件的可重复使用的缝合器。 Thus, in at least one embodiment, it may be provided above the stapler comprising an anvil member and a reduced member of the stapling head can be reused. 此外,在至少一个实施例中,包括钉仓的砧座和/或缝合头也可以是一次性的。 In addition, in at least one embodiment, the anvil includes staple cartridge and / or stitching head may also be disposable.

[0072] 在至少一个示例性实验中,通过将每个部件与部件标准列表进行对比以查看是否需要该部件,实现上述部件数的最少化。 [0072] In at least one exemplary experiment, each member by the standard component list to see whether they require a comparison member, to achieve the above-mentioned minimization of the number of parts. 剩下的仅是以上列出和出于组装原因而需要的部件、具有独特材料性质的部件,或者相对于缝合器中其他部件运动的部件。 The remaining listed above are only for assembly reasons and required parts, the unique material properties of components, or a suturing device with respect to another component member.

[0073] 在多个实施例中,缝合头组件能够包括锁定特征,以便在插入至外科缝合器的一部分内期间,阻止或防止缝钉驱动器意外从钉仓击发或驱动缝钉。 [0073] In various embodiments, the stapling head assembly can include a locking feature, so that, during the insertion portion of the surgical stapler to prevent or to prevent accidental firing of the staple driver or drive the staples from the staple cartridge. 更详细地说,现在参见图19-20,缝合头组件230可大体类似于上述的缝合头30和/或130,从而使缝合头组件230可例如用作外科缝合器1和/或101的元件。 In more detail, now to Figure 19-20, the suture head assembly 230 may be substantially similar to the above stapling head 30 and / or 130, so that the stapling head assembly 230 can for example be used as a surgical stapling device 1 and / or 101 . 换句话讲,缝合头组件230可如上文分别针对缝合头30和130所述而被插入至轴12或112中。 In other words, the stapling head assembly 230 may be as described above and 130, respectively, for the stapling head 30 is inserted into the shaft 12 or 112.

[0074]因此,更详细地说,缝合头组件230可包括钉仓233、芯235、从芯235延伸的至少一个缝钉驱动器234、和壳体239,钉仓233用于支撑一个或多个外科缝钉(图中未示出;然而, 例如参见图7B中的缝钉31 ),芯235可相对于钉仓233活动,壳体239能够至少部分地保持钉仓233并可动地容纳芯235和缝钉驱动器234。 [0074] Thus, more particularly, the suture head assembly 230 can include staple cartridge 233, a core 235, at least one staple drive 235 extending from the core 234 and the housing 239, cartridge 233 for supporting one or more surgical staples (not shown; however, see e.g., FIG. 7B the staples 31), the core 235 can be moved relative to staple cartridge 233 activity, the housing 239 can be at least partially retain staple cartridge 233 and movably accommodating the core 235 and staple driver 234. 如上文所述,缝钉驱动器234可从钉仓接合并驱动缝钉。 As described above, the staple driver 234 can be accessed from the staple cartridge combined driving staples.

[0075] 参见图21,在至少一个实施例中,缝钉驱动器234和芯235可以一体地连接和/或形成。 [0075] Referring to FIG. 21, in at least one embodiment, the staple driver 234 and 235 may be integrally connected to the core and / or form. 例如,各缝钉驱动器234可可操作地联接到芯235,每一缝钉驱动器均可由相同的材料形成,例如由塑料材料形成。 For example, each staple driver 234 can be operatively coupled to the core 235, each staple driver can be formed of the same material, e.g., formed of a plastic material. 接片236可自芯上突出,这些接片236能够接合驱动带80或驱动杆180(分别参见图4和图18)。 Tab 236 projecting from the core, the tabs 236 to engage the drive belt 80 and drive rod 180 (see FIGS. 4 and 18, respectively). 在任何情况下,如同例如上述缝合头30-样,驱动带80或驱动杆180的致动可致使芯235并进而使缝钉驱动器234击发,从而从钉仓233驱动或弹出缝钉。 In any case, as in the above example, the suture head 30- comp, drive belt 80 or the drive rod 180 of the actuator 235 may cause the core and thereby causes the firing staple driver 234 to drive or eject staples from the staple cartridge 233. [0076]如图20所示,在至少一个实施例中,壳体239可另外包括至少一个保持构件237,保持构件237能够弹性地和/或挠性地使缝合头30偏转并使缝合头30能够例如在形成于主体的轴部12中的对应孔15(参见图3)处可释放地附接到主体的轴部12。 [0076] 20, at least one embodiment, the housing 239 may additionally comprise at least one retaining member 237, retaining member 237 can be resiliently and / or flexibly deflecting head 30 so that the suture and the suture head 30 It can be, for example in the shaft portion of the shaft portion 12 corresponding to the hole formed in the body 15 (see FIG. 3) at releasably attached to the body 12. 每一保持构件237可还包括释放按钮,例如如图19-20所示。 Each holding member 237 may further include a release button, such as shown in Figure 19-20. 因此,当被插入于缝合器主体10(图3)的轴部12中时, 缝合头组件230(图19)可通过以下方式移走:按下各保持构件237上的相应按钮,然后转动头部30,使得接片36从由驱动带80的远端驱动表面82形成的凹口中脱开,最后将缝合头组件230拉离主体10。 Thus, when the shaft portion is inserted into the stapler body 10 (FIG. 3) of 12, the stapling head assembly 230 (FIG. 19) can be removed by the following manner: press the corresponding button on each holding member 237, and then the rotating head section 30, so that the tab 36 from the recess 80 by the distal end of the drive belt drive surface 82 is formed disengaged, the stapling head assembly 230 and finally pulled away from the body 10.

[0077]如在下文中所更详细说明,当对保持构件施加足够的外力(例如在将缝合头组件插入至轴内期间由外科缝合器1(参见图4)的轴部12提供)时,保持构件237能够从第一位置运动至第二位置。 [0077] As described in more detail below, when the holding member to exert sufficient force (e.g., in the stapling head assembly is inserted into the surgical stapler 1 (see FIG. 4) of the shaft portion 12 to provide during an inner shaft), the retainer member 237 can be moved from a first position to a second position. 第一位置可以是未被按下位置,而第二位置可以是被按下位置,在第二位置上,保持构件237既可接触也可不接触芯235。 The first position may be not depressed position and the second position can be pressed down and a second position, the holding member 237 are in contact both the core 235 without touching. 当保持构件237处于第二位置时,可防止缝钉驱动器234从钉仓233驱动或弹出缝钉,由此在将缝合头组件230插入于外科缝合器的至少一部分内期间为缝合头组件230提供击发锁定特征。 When the holding member 237 is in the second position, the staple driver 234 can be prevented from at least a portion of the cartridge 233 during the pop-up or drive the staples, thereby stapling head assembly 230 in the insert 230 to provide a surgical stapler for the stapling head assembly firing locking feature.

[0078]在至少一个实施例中,为使缝合头组件230具有额外的锁定能力,芯235还可包括凹槽240,凹槽240被构造成并且其尺寸被设定成在保持构件237处于第二位置时容纳保持构件237。 [0078] In at least one embodiment, for the stapling head assembly 230 with the additional capability of locking the core 235 may also include a recess 240, the recess 240 is configured and dimensioned in the holding member is set to be in the first 237 receiving member 237 while holding the second position. 例如,参见图21,凹槽240可设置于芯235的表面中,且凹槽240可限定于例如两个侧壁241与242之间。 For example, referring to Figure 21, the groove 240 may be disposed on the surface of the core 235 and the recess 240 may be defined between two side walls 241 and 242, for example. 在此种实施例中,至少部分地由于被按下的保持构件237与侧壁241、 242之间的干涉、和/或至少部分地由于被按下的保持构件237与芯235的表面之间的摩擦, 可在保持构件237被按下至凹槽240中时防止芯235以及进而防止缝钉驱动器234相对于壳体239(参见图19)运动。 In such an embodiment, due to being pressed between the retaining member to interfere with the sidewall 237 241, 242 between the, or at least partially and at least partially due to the surface / retaining member 237 is pressed with the core 235 the friction member 237 is held in the recess 240 when pressed to prevent the core 235 and thereby preventing the staple driver 234 with respect to the housing 239 (see FIG. 19) movement.

[0079] 如上文所述,在多个实施例中,保持构件237可弹性地偏转。 [0079] As described above, in various embodiments, retention member 237 can be elastically deflected. 换句话讲,保持构件237可弹性地偏转,从而在因受到外力而偏转之后,保持构件237可回弹或以其他方式返回至其原始位置。 In other words, the holding member 237 elastically deflect, so that after deflection by external force due to the retention member 237 may be resilient or otherwise returned to its original position. 更详细地说,各保持构件237可分别包括形成于壳体239中的悬臂。 More particularly, each holding member 237 may include, respectively, formed in the housing 239 of the cantilever. 在此种实施例中,参见图19,悬臂式保持构件可围绕由壳体235所限定的纵向轴线"L"弯曲,以例如与外科缝合器1(参见图4)的管状主体10的曲率相关联。 In such an embodiment, referring to Figure 19, cantilevered by the holding member is rotatable around the housing 235 defining a longitudinal axis "L" bent, for example, the curvature of the surgical stapler 1 (see FIG. 4) of the tubular body 10 associated Union. 换句话讲,保持构件237可如图19所示围绕钉仓壳体沿径向弯曲或卷曲。 In other words, the holding member 237 may be 19 around the cartridge casing bent or curled radially. 作为另外一种选择,保持构件可为线性的或在与壳体239 所限定的纵向轴线L平行的方向上延伸。 Alternatively, the retaining member may be linear or extend in a direction parallel to the longitudinal axis L defined by the housing 239.

[0080] 在至少一个实施例中,保持构件237可为一体的并与壳体239形成一体,从而使壳体239与保持构件237由同一件材料形成和/或模制而成。 [0080] In at least one embodiment, the retaining member 237 may be integral with the housing 239 integrally formed so that the housing 239 and the holding member 237 is formed from the same piece of material and / or molded. 在此种实施例中,壳体239可由塑料材料制成,例如由尼龙、聚碳酸酯、聚醚酰亚胺(PEI)或聚醚醚酮(PEEK)制成。 In such an embodiment, the housing 239 may be made of plastic material, for example made of nylon, polycarbonate, polyetherimide (PEI), polyether ether ketone (PEEK). 另外,在至少一个实施例中,芯可由塑料材料制成,例如由尼龙、聚碳酸酯、聚醚酰亚胺(PEI)或聚醚醚酮(PEEK)制成。 Further, in at least one embodiment, the core may be made of a plastic material, for example made of nylon, polycarbonate, polyetherimide (PEI), polyether ether ketone (PEEK).

[0081 ] 在至少一个实施例中,可参照图22-24来理解与芯235和/或凹槽240相互作用的保持构件237的操作。 [0081] In at least one embodiment, the operation can be understood with the core 235 and / or the recesses 240 of the holding member 237 interacting with reference to Figures 22-24. 图22示出缝合头组件230的一部分被初始地插入圆形缝合器的主体10的轴部12中。 Figure 22 shows a portion of the stapling head assembly 230 is initially inserted into the circular stapler main body portion 10 of the shaft 12. 主体10是以虚线进行显示,以更好地示出缝合头组件230的位于缝合器主体内的部分。 The body 10 is a dotted line is displayed, to better illustrate the stapling head assembly 230 is positioned within the main body portion of the suture. 保持构件237可分别包括斜面243,由图可见,在轴部12即将接触保持构件237的斜面243之前,保持构件237仍处于未偏转位置或第一位置。 Holding member 237 may include a ramp 243, respectively, before seen from the figure, the shaft portion 12 coming into contact holding member 237 of the ramp 243, the holding member 237 is still in the undeflected position or first position. 沿近端方向"PD"进一步推进缝合头组件可使轴部12接触保持构件237并开始使保持构件237朝芯235向内偏转。 The proximal direction "PD" to further promote the stapling head assembly 12 make contact with the shaft portion 237 and holding member holding member 237 begins to deflect inwardly towards the core 235. 图23示出缝合头组件230被进一步插入于圆形缝合器的主体中。 Figure 23 shows a stapling head assembly 230 is further inserted in the circular stapler body. 由图可见,圆形主体10的内壁使保持构件237保持于被按下位置或第二位置。 Seen from the figure, the inner wall of the circular body 10 of the holding member 237 is held in the depressed position or the second position. 在被按下位置或第二位置上,保持构件237可被容纳于凹槽240(参见图21)中,以由此防止芯235沿远端方向"DD"运动。 Being pressed or second position, the holding member 237 can be accommodated in the recess 240 (see FIG. 21), thereby to prevent the core 235 in the distal direction "DD" movement. 另外,例如凹槽侧壁241可防止保持构件237沿远端方向DD明显地运动。 In addition, for example, side wall of recess 241 prevents the holding member 237 in the distal direction DD apparent movement. 通过使缝合头组件进一步沿近端方向(参见图22)运动并接着使保持构件237的释放按钮对准主体10中的孔15,可允许保持构件弹性地返回至未被按下位置,从而使保持构件237不仅将缝合头组件230保持于圆形缝合器主体10 中、而且还使凹槽240和/或侧壁241、242通畅以便能够致动芯235和缝钉驱动器234并从钉仓233(参见图19)驱动缝钉。 By stapling head assembly further in the proximal direction (see Fig. 22) movement and then the holding member 237 of the release button is aligned apertures 15 in the body 10 may be allowed to remain resilient member returns to the not pressed position, so that the 237 will not only maintain the stapling head assembly holding member 230 in a circular stapler body 10, but also to make the recess 240 and / or the side walls 241, 242 open to allow the actuation of the core 235 and staple driver 234 and staple cartridge 233 from (see FIG. 19) driving the staples. 例如,图24示出被完全插入于圆形缝合器主体10中的缝合头组件230,其中保持构件237处于此种未被按下位置并至少部分地位于孔15内。 For example, Figure 24 shows 10 is fully inserted in the stapling head assembly of the circular stapler body 230, in which the holding member 237 is not pressed in this position and at least partially located within the bore 15. 此外,如图24所示,芯的接片236被容纳于驱动带80的凹口中,以容纳来自驱动带80的致动运动,此类似于上文关于例如缝合头30(参见图4)所述。 Further, as shown, the tabs 236 of the core drive belt 24 is accommodated in the recess 80 to accommodate the drive belt 80 from the actuating movement, similar to the example above regarding stapling head 30 (see FIG. 4) said.

[0082]缝合头组件的其他型式可包括上文所述的各种特征。 Other types [0082] The stapling head assembly may include various features described hereinabove. 例如,在至少一个实施例中并参见图25-26,缝合头组件330可关于纵向轴线"L"而大体径向对称。 For example, at least one embodiment and with reference to Figure 25-26, stapling head assembly 330 about the longitudinal axis "L" and a generally radially symmetrical. 然而,在此种实施例中,缝合头组件330可在其他方面类似于例如上文所述的缝合头组件230和/或缝合头30。 However, in such an embodiment, the suture head assembly 330 may be similar, for example stapling head assembly 230 described above and / or stitching head 30 in other ways. 例如,缝合头组件330可包括用于支撑一个或多个外科缝钉的钉仓333、相对于所述钉仓333可动的芯335、从所述芯335延伸的至少一个缝钉驱动器334、和壳体339,所述壳体339能够至少部分地保持所述钉仓333并可动地容纳所述芯335和所述至少一个缝钉驱动器334。 For example, the suture head assembly 330 may include for supporting one or more surgical staples of the staple cartridge 333, staple cartridge 333 with respect to the movable core 335, the core 335 extending from the at least one staple driver 334, and the housing 339, the housing 339 can be at least partially retain said staple cartridge 333 and movably accommodating the core 335 and the at least one staple driver 334. 缝钉驱动器334能够从钉仓333接合并驱动缝钉。 Staple driver 334 from the staple cartridge 333 can engage and drive the staples. 另外,所述壳体还可包括至少一个保持构件337,所述保持构件337能够在对保持构件337施加足够的外力时从第一位置运动至第二位置。 Further, the housing may further comprise at least one retaining member 337, the holding member 337 capable of holding member 337 when a sufficient external force is applied from a first position to a second position. 进一步,当保持构件337处于第二位置时可防止所述至少一个缝钉驱动器从钉仓驱动缝钉。 Further, when the holding member 337 is in the second position prevents the at least one staple driver drives the staple from the staple cartridge. 在至少一个实施例中,所述芯还可包括凹槽340,凹槽340被构造成并且其尺寸被设定成在保持构件337处于第二位置时容纳保持构件337。 In at least one embodiment, the core may also include a recess 340, the recess 340 is configured and dimensioned to be set when the holding member 337 is in the second position receiving holding member 337. 另外,不同于缝合头组件230,组件330还可包括切割构件332,切割构件332可操作地联接到芯335。 Further, unlike stapling head assembly 230, assembly 330 may further include a cutting member 332, cutting member 332 is operatively coupled to the core 335. 因此,当保持构件处于被按下位置以防止芯335相对于壳体339运动时,也可防止切割构件332和/或缝钉驱动器334相对于壳体339运动,从而防止切割构件332和/或钉仓333中的缝钉被意外击发。 Accordingly, when the holding member is pressed in position when the core 335 to prevent relative movement of the housing 339, cutting member 332 can be prevented and / or staple driver 334 with respect to the movement of the housing 339, thereby preventing the cutting member 332 and / or the cartridge 333 is accidentally firing the staples. 另外,芯335可包括从芯335沿横向突出的接片336,以用于可操作地接合如上文关于缝合头组件30、130和/ 或230所述的外科缝合器的驱动带或驱动杆。 In addition, the core 335 may include a core 335 in the lateral direction from the projecting tabs 336, for operatively engaged as described above with respect to the suture head assembly 30, 130 and / or 230 of the surgical stapler of the drive belt or drive rod. 在再一些替代实施例中,壳体能够在其内可操作地支撑一个或多个外科缝钉。 In still other alternative embodiments, the housing can be operably supporting one or more surgical staples therein. 在此种替代实施例中,不需要具有单独的钉仓来可操作地支撑外科缝钉。 In such an alternative embodiment, it does not need to have a separate operably support a staple cartridge of surgical staples. 而是,壳体能够支撑缝钉,从而在接触缝钉驱动器时,缝钉被驱动出壳体外。 Instead, the case could support a staple, so that when the contact staple drivers, staples are driven hatched in vitro.
