Disposable Endo-GIATechnical field
This utility model relates to technical field of medical instruments, especially a kind of disposable Endo-GIA.
Background technology
Linear cutting anastomat generally forms by nail-anvil assembly with the nail bin groupware of flexible handle, flexible handle is first opened by operation consent, nail-anvil assembly and nail bin groupware are placed on tissue two rear flank to be performed the operation involutory, again flexible handle is closed, by nail-anvil assembly and nail bin groupware locking, then driven forward percussion button, percussion button connects pushing block, pushing block connects nail pushing plate and cutter, suturing nail is released and is carried out tissue apposition by nail pushing plate, tissue after stitching cuts off by cutter reach simultaneously, completes operation.
The pushing slice of nail correspondence of existing disposable Endo-GIA loads in nail bin hole, rises or decline under the effect of nail pushing plate.For preventing pushing slice of nail from dropping out, needing to make burn frock in the past, acting on nail bin and making its correspondence position melt varus with spacing pushing slice of nail.Because burn affects by time-temperature, in the process of batch production, stability is difficult to ensure, needs change method; In addition, when nail bin is mounted on assembly clamping plate, Chang Yin is not in place and causes the failure of operation, and tracing it to its cause is whether nail bin puts in place when docking with clamping plate and all do not have obvious basis for estimation, brings great puzzlement when using to doctor.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of disposable Endo-GIA.
This utility model solves the technical scheme that its technical problem adopts: a kind of disposable Endo-GIA, there are nail bin and assembly clamping plate, described nail bin is arranged in assembly clamping plate, the intermediate lateral in described nail bin front is provided with linear type tool slot, the both sides of tool slot are evenly provided with two holes, nail storehouse, and nail bin is provided with pushing slice of nail in hole, and the front end of tool slot is provided with location rod aperture, the intermediate lateral at the nail bin back side is provided with a cover plate, and the centre two that cover plate is covered in nail bin hole is arranged; The both sides of described nail bin end are provided with circular convex bubble, and the nail bin wall thickness of convex bubble region is thinner than other regions of nail bin, and described assembly clamping plate both sides are provided with the pit matched with convex bubble, are provided with the interior chamfering preventing convex bubble wearing and tearing below described pit.
Further, the two ends of described cover plate are provided with catching groove, and the described nail bin back side is provided with the discount buckling into above-mentioned catching groove.
Further, the end of described nail bin is provided with briquetting hole.
The beneficial effects of the utility model are: this utility model prevents pushing slice of nail from dropping out by increasing a cover plate at the nail bin back side, easily and effectively, ensure stability in the process of batch production; The sound sent when being coordinated by convex bubble and pit, obviously can be judged that nail bin docks with assembly clamping plate and put in place, bring great convenience when using to doctor.

Detailed description of the invention
By reference to the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with this utility model.
As shown in Fig. 1 ~ 5, a kind of disposable Endo-GIA, there are nail bin 1 and assembly clamping plate 2, nail bin 1 is arranged in assembly clamping plate 2, and the intermediate lateral in nail bin 1 front is provided with linear type tool slot 3, and the both sides of tool slot 3 are evenly provided with two holes, nail storehouse 4, in nail bin hole 4, pushing slice of nail is installed, the front end of tool slot 3 is provided with location rod aperture 6, and the intermediate lateral at nail bin 1 back side is provided with a cover plate 7, and the centre two that cover plate 7 is covered in nail bin hole 4 is arranged; The both sides of nail bin 1 end are provided with circular convex bubble 8, and nail bin 1 wall thickness of convex bubble 8 region is thinner than other regions of nail bin 1, and assembly clamping plate both sides 2 are provided with the pit 9 matched with convex bubble 8, are provided with the interior chamfering 10 preventing convex bubble 8 from wearing and tearing below pit 9.Wherein, nail bin 1 wall thickness of convex bubble 8 region is thinner than other regions of nail bin 1, is to increase elasticity.
Further, the two ends of cover plate 7 are provided with catching groove, and nail bin 1 back side is provided with the discount buckling into above-mentioned catching groove.
Further, the end of nail bin 1 is provided with briquetting hole 11.
Have obvious sensation when convex bubble 8 enters pit 9 and have the sound of " clatter ", now showing that nail bin 1 is in place.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to right.
