Abstract

The utility model relates to an anastomat for linear cutting, which comprises a body, a nail barn, a nail anvil and a cutting knife, wherein the back part of the cutting knife is provided with a push handle provided with a groove of the push handle and the body is provided with a stop block. The nail barn is rotationally connected with an oppression cross beam which is provided with two working positions. Under a first working position, the oppression cross beam presses on the push handle and the stop block disengages from the groove of the push handle. Under a second working position, the oppression cross beam disengages from the push handle and the stop block is inserted in the groove of the push handle. After the cutting knife is pushed frontward once, the oppression cross beam is rotated and lies in the second working position, the stop block is inserted in the groove of the push handle and the push handle is unable to be pushed for the second time. Medical negligence caused by that the cutting knife is pushed by mistakes can be prevented.

Description

Linear cutting anastomat

Technical field

This utility model relates to a kind of medical apparatus and instruments, especially for the linear cutting anastomat of tissue apposition.

Background technology

In the prior art, linear cutting anastomat comprises body, is arranged at nail bin and nail anvil and cutter on the body, and cutter cuts tissue, and the back is by sewing up tissue nail bin and cooperating of nail anvil.But because cutter can freely promote, so after finishing the cutter rollback when performing the operation, the doctor still can be owing to neglecting the propelling cutter, and the suturing nail in the nail bin has used up at this moment, easily causes malpractice.

Summary of the invention

This utility model purpose provides a kind of linear cutting anastomat, and its cutting and stitching operation back cutter can be locked.

For achieving the above object, the technical solution adopted in the utility model is: a kind of linear cutting anastomat, comprise body, be arranged at the nail bin on the described body, the nail anvil relative with described nail bin, be arranged at advance cutter in the groove of cutter on the described body, the rear portion of described cutter has the handle of pushing away, described pushing away has the handle of pushing away groove on the handle, described body is provided with stopper, be rotatably connected to an end of compressing crossbeam on the described nail bin, described compressing crossbeam has two operating positions, under first operating position, described compressing crossbeam is pressed in described pushing away on the handle, the described handle groove that pushes away breaks away from described stopper, under second operating position, described compressing crossbeam disengaging pushes away handle, and described stopper is inserted in and pushes away in the handle groove.

Because technique scheme utilization, this utility model compared with prior art has following advantage: nail bin is provided with the compressing crossbeam, when the compressing crossbeam is pressed in when pushing away on the handle, pushing away handle is pressed down, the stopper disengaging pushes away the handle groove, push away handle and can promote cutter and in cutter is advanced groove, advance, cut and organize and cooperate suture tissue with nail anvil by nail bin by cutter.In pushing ahead the process of cutter, push away handle and also promote to oppress the crossbeam rotation, the compressing crossbeam becomes second operating position from first operating position, after pushing away handle and retreating, push away handle and lack compressing pressing down of crossbeam and making and push away handle and rise, stopper is inserted in and pushes away in the handle groove, makes that pushing away handle can't promote forward once more, cutter is promptly locked, can prevent to promote cutter once more because of human error.

The specific embodiment

Referring to accompanying drawing 1-accompanying drawing 2, a kind of linear cutting anastomat comprises body 5, is arranged at nail bin 2 on the described body 5, the nail anvil 3 relative with described nail bin 2, is arranged at the cutter 4 on the described body 5, and the rear portion of described cutter 4 has the handle of pushing away 6.This utility model is used for operations such as the internal organs excision of surgical operation and reconstruction of digestive tract, push away handle 6 during use, make 4 pairs of tissues of cutter cut, suturing nail then is installed in the nail bin 2, by cooperating of nail bin 2 and nail anvil 3, when cutter 4 carries out cutting operation, tissue is carried out sew application.

Referring to accompanying drawing 3-accompanying drawing 7, described pushing away has the handle of pushing away groove 10 on the handle 6, and described body 5 is provided with stopper 7.Be rotatably connected to compressing crossbeam 8 on the described nail bin 2, described compressing crossbeam 8 has two operating positions, under first operating position (as accompanying drawing 4 and accompanying drawing 6), described compressing crossbeam 8 is pressed in and pushes away on the handle 6, and described stopper 7 disengagings push away handle groove 10, are pressed down owing to push away handle 6, therefore cutter 4 can be pushed and move ahead, under second operating position (as accompanying drawing 5 and accompanying drawing 7), described compressing crossbeam 8 disengagings push away handle 6, and described stopper 7 is inserted in and pushes away in the handle groove 10.Described push away to have on the handle 6 in order to what push compressing crossbeam 8 open push away handle projection 9, the described handle projection 9 that pushes away is pushing away on the handle 6 projection longitudinally, and the described handle projection 9 that pushes away vertically is being higher than compressing crossbeam 8, described pushing away between handle 6 and the body 5 also is provided with reed 11.Before operation technique, compressing crossbeam 8 presses down and pushes away handle 6, and stopper 7 promptly breaks away from and pushes away handle groove 10, and pushing away handle 6, can to promote cutter 4 mobile and tissue is carried out cutting operation in cutter is advanced groove 12; And in the moving process that advances of cutter 4, pushing away handle projection 9 moves with pushing away handle 6, when push away handle projection 9 push open the compressing crossbeam 8 after, push away handle 6 promptly since the elastic force effect of reed 11 and on lift, operation finishes behind cutter 4 rollbacks, stopper 7 is inserted in and pushes away in the handle groove 10, pushing away handle can't move forward once more, cutter 4 is promptly automatically locked, cutting once more after 4 pairs of tissues of cutter cut or cut once in the time of can preventing in nail bin 2 no suturing nail, thus can improve the safety of operation.
