Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of Endo-GIA.
Background technology
Linear cutting anastomat generally forms by nail-anvil assembly with the nail bin groupware of flexible handle, before operation, first flexible handle is opened, nail-anvil assembly and nail bin groupware are placed on to tissue to be performed the operation two rear flank involutory, again flexible handle is closed, by nail-anvil assembly and nail bin groupware locking, then promote forward percussion button, percussion button connects pushing block, pushing block connects nail pushing plate and cutter, nail pushing plate is released suturing nail to carry out tissue apposition, the tissue after sewing up is cut off in cutter reach simultaneously, completes operation.The percussion button of existing linear cutting anastomat is arranged on a side of apparatus, is conventionally convenient to right-hand operated, and it is not easily that left-handed operator uses, and the little person of singlehanded strength also cannot both hands percussion.In addition, the possibility that the percussion button of existing linear cutting anastomat exists mistakenly hit to send out, thus to work, bring inconvenience, there is potential safety hazard.
Summary of the invention
That the percussion button of the technical problem to be solved in the present invention Endo-GIA uses is inconvenient, have potential safety hazard, provides a kind of simple in structure, the Endo-GIA that left hand, the right hand or both hands all can convenient operation.
The technical scheme that technical solution problem of the present invention adopts is, Endo-GIA, comprise position fixing handle, percussion button, pushing block, push jack, pushing block connects push jack and cutter, described percussion button is arranged on the left and right sides of pushing block, and left side is that button is sent out in left click, and right side is that button is sent out in right click, left click is sent out button and is sent out button with right click and be connected by crossbeam, and crossbeam is connected with pushing block through pushing block.
As a kind of optimal way, percussion button and crossbeam adopt bearing pin to be connected, pull the trigger button and take bearing pin and fold to the inside or open laterally as turning cylinder.On described percussion button, be provided with percussion button lock pin, crossbeam is provided with and the retaining structure of pulling the trigger button lock pin and coordinating.On described crossbeam, be also provided with percussion locking position, guarantee to pull the trigger button and in pushing course, do not rotate forward.
As a kind of optimal way, described position fixing handle is provided with guide groove, and the guide groove on percussion button relative localization handle is provided with flange.Percussion process flange and guide groove buckle, prevent that nail-anvil assembly and nail bin groupware from throwing off midway.
Endo-GIA of the present invention all arranges percussion button in the left and right sides of apparatus; convenient operation person is according to being accustomed to separately selecting percussion button, and both sides percussion button can also be pulled the trigger simultaneously, and for hands strength, little person facilitates; two ends equilibrium is simultaneously had an effect, and can guarantee the stability of the process of pulling the trigger.Bilateral of the present invention percussion button can be set to foldable structure, when folding, can not pull the trigger, and opens just can pull the trigger afterwards, has increased the safety of operation.Adopt the percussion button of foldable structure also can reduce the overall dimensions of apparatus, thereby reduce Package size, reduce costs, be convenient to transportation.

In figure, 1 position fixing handle, 2 percussion buttons, 3 pushing blocks, 4 push jacks, 5 cutter, 6 crossbeams, 7 bearing pins, 8 percussion button lock pins, 9 springs, 11 guide grooves, button is sent out in 21 left clicks, and button is sent out in 22 right clicks, 100 Handheld Divisions, 200 crossbeam connecting portions, clamping part on 201,202 times clamping parts, 203 pin shaft holes, 204 lockpin holes, 205 flanges, 61 close screens, 62 open screens, 63 percussion locking positions, 64 back-offs, 31 back-off grooves.
The specific embodiment
As depicted in figs. 1 and 2, Endo-GIA, comprise position fixing handle 1, percussion button 2, pushing block 3, push jack 4, pushing block 3 connects push jack 4 and cutter 5, described percussion button 2 is arranged on the left and right sides of pushing block 3, and left side is that button 21 is sent out in left click, and right side is that button 22 is sent out in right click, left click is sent out button 21 and is sent out button 22 with right click and be connected by crossbeam 6, and crossbeam 6 is connected with pushing block 3 through pushing block 3.
Percussion button 2 adopts bearing pin to be connected with crossbeam 6, shown in Fig. 3 is that button 21 structures are sent out in left click, right click is sent out button 22 and is sent out button 21 for symmetrical structure with left click, the base portion of percussion button is crossbeam connecting portion 200, the upper clamping part 201 of crossbeam connecting portion and lower clamping part 202 are provided with pin shaft hole 203, the two clamping crossbeam 6 rear pin shaft hole 203 is relative with the hole on crossbeam, by bearing pin 7, connects.The afterbody of percussion button is Handheld Division 100, passes through Handheld Division 100 application of forces during percussion.Handheld Division 100 and 203 of the pin shaft holes of percussion button are provided with lockpin hole 204, percussion button lock pin 8 is arranged in lockpin hole 204, crossbeam 6 is provided with and the retaining structure of pulling the trigger button lock pin 8 and coordinating, its preferred structure can be referring to Fig. 4 and Fig. 5, percussion button 2 is when closed condition, percussion button lock pin 8 is ejected by spring 9, and percussion button lock pin 8 pins location by the screens 61 of closing on crossbeam.Open percussion during button 2, press percussion button lock pin 8, it gets out of the way closes screens 61, and percussion button 2 launches forward, arrives while opening screens 62, and due to the effect of spring 9, percussion button lock pin 8 flicks again, and that blocks crossbeam opens screens 62, pulls the trigger button in open mode.On described crossbeam 6, be also provided with percussion locking position 63, guarantee to pull the trigger button and in pushing course, do not rotate forward.In addition, in order to realize crossbeam, be connected with 6 the quick of pushing block 3, can adopt back-off to connect, back-off 64 is set on crossbeam 6 and coordinates with the back-off groove 31 on pushing block 3.
As shown in Figure 7, described position fixing handle 1 is provided with guide groove 11, and the guide groove 11 on percussion button 2 relative localization handles is provided with flange 205.The flange 205 of pulling the trigger in percussion process on button is limited to the interior slip of position fixing handle guide groove 11 all the time, prevents that maloperation midway from causing flexible handle release, and apparatus is opened, and causes operation to be forced to stop.
