Description
Technical field
The present invention relates to a kind of circular-pipe anastomat, the nail-head component of especially a kind of circular-pipe anastomat, belong to technical field of medical instruments.
Background technology
People's history to understanding existing more than 4000 years of hemorrhoid, the traditional method of internal hemorrhoid treatment, including injection of sclerosing agent, rubber snare bundle and various forms of surgical operations etc..These methods are all treat for hemorrhoid itself, it is intended to make blood stasis reduce or disappear.In the surgical operation of hemorrhoid excision, one is had to be called PPH operation method, mucosa procedure in the hemorrhoid namely carried out under the help of circular-pipe anastomat.
US Patent No. 6083241 discloses a kind of circular-pipe anastomat, its nail-head component includes nail anvil and nail barrel, sets nail bin, pushing slice of nail, nail in nail barrel, and described nail anvil is relative with nail barrel and puts, mucosa in hemorrhoid is pulled in nail barrel by operation, by mucosa ring cutting in hemorrhoid when coincideing.
The nail barrel of the circular-pipe anastomat commonly used at present, due to the restriction of himself structure so that its form provided to doctor in the use procedure of operation is limited, and is unfavorable for drawing in and holding more tissue to be cut of tissue, there is bigger limitation.
Summary of the invention
Present invention aim at solving above-mentioned technical problem, it is provided that a kind of circular-pipe anastomat can realize the jumbo nail-head component of big form.
The technical scheme is that the nail-head component of a kind of circular-pipe anastomat, at least include nail barrel and nail anvil, described nail barrel includes housing, and the near-end of described housing, for being connected with the body of circular-pipe anastomat, is provided with only tube and pushing slice of nail in described housing；Described nail anvil includes the pin anvil ring and the pin anvil shaft that are mutually permanently connected, described pin anvil shaft slides in described only tube, the housing side opening of described nail barrel is provided with at least one opening, described opening is through with the first cavity for holding tissue to be cut, the far-end of described only tube to the distance of the near-end of housing less than the most distal edge of described opening to the distance of the near-end of housing, have at least the first cavity partly to reveal from described opening.
Preferably, the housing middle-end of described nail barrel offers four symmetrical openings, is equipped with reinforcement between adjacent apertures.
Preferably, in the housing cross-sectional of described nail barrel, the central angle of described opening is more than the central angle of reinforcement.
Preferably, the shape of described pushing slice of nail and described nail barrel match, and offer the second cavity inside described pushing slice of nail middle-end, and described second cavity is directed at the first cavity of described nail barrel.
Preferably, the proximal extension of described only tube, to the near-end of housing, also extends to the near-end with only tube with the near-end of the described only described pin anvil shaft that tube coordinates and cooperates.
Preferably, being provided with at least one gathering sill, described pin anvil shaft correspondingly arranges at least one guiding rib in the through hole of described only tube, described guiding rib can slide in described gathering sill.
The invention have the advantage that
1. by offering four symmetrical openings in nail barrel middle-end, can providing big form in operation uses, only the reduction of tube and reinforcement is arranged, and the relative set of pushing slice of nail so that be easy to drawing in and hold and more cutting tissue of tissue in operation；
2. stop tube proximal extension to arrange, compensate for nail barrel and reinforcement reduces the deficiency arranging the axial and circumferential intensity brought；Pin anvil shaft near-end is also extended, adds pin anvil shaft and coordinating of stopping tube.

Fig. 2 is the structural representation of nail barrel in the embodiment of the present invention one；
Fig. 3 is the structural representation of pushing slice of nail in the embodiment of the present invention one.
Wherein: 1, nail barrel；2, pin anvil ring；21, pin anvil shaft；3, opening；31, most distal edge；4, reinforcement；5, the first cavity；11, housing；12, near-end；13, tube is stopped；14, pushing slice of nail；15, the second cavity.
Detailed description of the invention
Embodiment one: shown in Figure 1, the invention provides the nail-head component of a kind of circular-pipe anastomat, at least includes the pushing slice of nail 14 shown in the nail barrel 1 shown in Fig. 2, Fig. 3 and nail anvil.Described nail anvil includes the pin anvil ring 2 and the pin anvil shaft 21 that are mutually permanently connected.
Shown in Fig. 2, described nail barrel 1 includes a housing 11, the near-end 12 of described housing 11 is for being connected with the body of circular-pipe anastomat, being provided with only tube 13 and pushing slice of nail 14 in described housing 11, only tube 13 includes a through hole, and this through hole is for making the pin anvil shaft 21 of nail anvil slide through, preferred embodiment is, only being provided with two gathering sills in the through hole of tube 13, described pin anvil shaft 21 correspondingly arranges two guiding ribs, described guiding rib can slide in described gathering sill.
In this preferred embodiment, the side opening in described nail barrel 1 is provided with four symmetrical openings 3, and such four sides opening is arranged can provide big form to medical personnel in operation, is equipped with reinforcement 4 between adjacent apertures 3.Described opening 3 is through with the first cavity 5 for holding tissue to be cut, the far-end of described only tube 13 arrives the distance of the near-end 12 of housing 11 to the distance of the near-end 12 of housing 11 less than the most distal edge 31 of described opening 3, the first cavity 5 having at least part reveals from described opening 3 so that be easy to drawing in and hold and more cutting tissue of tissue in operation.And in housing 11 cross section of described nail barrel 1, the central angle of described opening 3 is more than the central angle of reinforcement 4.Such big opening is arranged, and makes doctor have splendid observation visual angle when operation.
Further, one end of described reinforcement 4 and the housing 11 of nail barrel 1 are wholely set, and the length of the other end is equal to the length of described only tube 13.Shown in Fig. 3, the shape of described pushing slice of nail 14 and described nail barrel 1 match, and offer the second cavity 15 inside described pushing slice of nail 14 middle-end, and described second cavity 15 is directed at the first cavity 5 of described nail barrel 1.Pushing slice of nail 14 is similar with arranging of nail barrel 1, also for bringing bigger receiving space, holds more tissue to be cut.
The deficiency of the axial and circumferential intensity of the apparatus that the reduction in order to make up only tube 13 and reinforcement 4 brings, only tube near-end has carried out extended, simultaneously pin anvil shaft also corresponding proximal extension, and increase pin anvil shaft coordinates with only tube.Particularly as follows: the proximal extension of described only tube is to the near-end of housing, also extend to and the near-end of only tube with the near-end of the described only described pin anvil shaft that tube coordinates.
In the present invention be proximally and distally with surgical time apparatus location, the nearer one end of distance doctor is near-end, and distance doctor one end farther out is far-end.
All technical schemes that the present invention still has numerous embodiments, all employings to be equal to replacement or equivalent transformation and formed, all fall within the scope of protection of present invention.
