The specific embodiment

This utility model has disclosed a kind of cutting and binding instrument for surgery, is specially a kind of linear type cutting closer.Below in conjunction with accompanying drawing technical solutions of the utility model are described further.

As depicted in figs. 1 and 2, linear type cutting closer of the present utility model is the same with prior art, comprises upper and lower clamp 1,2, and is used for the closed handle 3 with upper and lower clamp 1,2 closures, and described closed handle 3 is connected with following clamp 2 bearing pins.When closed handle 3 is under pressure, can pivot, and the locking pin 5 that be arranged in clamp 1 middle part 11 this moment just can stick into the opening 8 that is positioned at closed handle 3 front ends, and owing to opening becomes oblique setting, it just can be closed together upper and lower clamp 1,2 to the pulling force of locking pin 5 generations.This operating process is consistent with prior art.

Described upper and lower clamp 1,2 includes near-end 9 and far-end 10, has a percussion push button 4 to connect near-end 9 at upper and lower clamp 1,2, is used for nail is pushed out of outside the nail bin 13, promotes cutting knife simultaneously and cuts off tissue.Described nail bin 13 and corresponding nail anvil are arranged on the far-end 10 of upper and lower clamp 1,2, and in the present embodiment, nail bin 13 is arranged on down the far-end 10 of clamp 2, and corresponding nail anvil is arranged on the far-end 10 of clamp 1, should design also consistent with prior art at present.

This utility model difference with the prior art is: be provided with balanced controls between the described upper and lower clamp 1,2, be the almost parallel setting after making the front end of described upper and lower clamp 1,2 be closed handle 3 closures, and leave a gap 12 between nail bin 13 surfaces and the relative nail anvil surface.Because prior art is the angle setting after upper and lower clamp 1,2 closures, will produce the nail uneven problem that is shaped like this, so be configured to just can not produce this problem after parallel when upper and lower clamp 1,2.

Specifically, the described balanced controls of this preferred embodiment comprise alignment pin 6 and the abutting part 7 that is arranged on down on the clamp 2, and described abutting part 7 is arranged on down the near-end 9 of clamp 2, and described alignment pin 6 is vertically set on down the distal surface of the nail bin 13 on the clamp 2.It is in the same plane that both are equivalent to the fulcrum of clamp 1.After upper and lower clamp 1,2 was closed, alignment pin 6 and abutting part 7 played a supporting role between upper and lower clamp 1,2, and the end-state that upper and lower clamp 1,2 is closed also is that only state is exactly that both are set in parallel.

This preferred embodiment is only for an only example, because alignment pin 6 is except the effect of playing the upper and lower clamp 1,2 of balance, also play one prevent to organize excessive and one allow upper and lower clamp 1,2 better localized effects, therefore, the setting of alignment pin 6 is achieved many things at one stroke.Certainly, balanced controls in this utility model also comprise other scheme except above-mentioned scheme, for example are arranged on the meeting device of upper and lower clamp 1,2 any positions, as long as be almost parallel after upper and lower clamp 1,2 is closed, this utility model just repeats no more.

Introduce the installation and the using method of this preferred embodiment below:

Closed handle 3 and following clamp 2 usefulness bearing pins are coupled together, on last clamp 1, fixedly install locking pin 5 then, then alignment pin 6 is installed on the nail bin 13, make it perpendicular to nail bin 13 planes, thereby the one end can exceed the nail bin plane.

During operation, tissue is placed between the bookbinding position of upper and lower clamp, promptly between nail bin surface and nail anvil surface.Then with upper and lower clamp closure, and depress closed handle 3, because the support of alignment pin 6 summits and abutting part 7 produces an isostatic gap 13, just be placed in this gap 13 between this moment upper and lower clamp and organize.This moment, tissue was clipped in up and down between the closed clamp firmly.

Because after the opening 8 of closed handle and locking pin 5 tight the contacts, can produce a pretightning force to upper and lower clamp, so when apparatus is pulled the trigger, the tension force that produces when nail is released from nail bin 13 is offset by pretightning force, and because the existence of alignment pin 6 and abutting part 7, the gap between the upper and lower clamp is also at equilibrium, the equally open phenomenon of shears can not occur, thereby guaranteed the concordance that nail is shaped, just improved the safety of operation.Because alignment pin 6 is arranged on the centrage of nail bin 13, there is a groove position corresponding on the last clamp 1, and when upper and lower clamp was closed, alignment pin 6 can enter in the groove, so alignment pin also has positioning action.

This utility model still has multiple concrete embodiment.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of this utility model.
