Abstract
The utility model provides a safety device of purse-string forceps. The safety device comprises a body and a moving slide block, and further comprises a limit piece on the body. The moving slide block is arranged in the limit piece and can slide relative to the limit piece. The moving slide block is provided with an elastic protrusion. In work, the protruding part of a cam collides with the moving slide block to push the moving slide block to move in the radial direction. When the moving slide block moves to a proper position, the limit piece clamps the elastic protrusion of the moving slide block, so that the moving slide block can not move, and a suture needle of the purse-string forceps can accurately hook threads. The utility model further provides the purse-string forceps comprising the safety device.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of safety of purse-string forceps.This utility model also relates to a kind of purse-string forceps that comprises above-mentioned safety.
Background technology
In medical science applied surgical operation, since the sixties in 20th century utility model first staple series products, Medical stapler has become the requisite a kind of medical apparatus and instruments aiding in edge of a knife sewing process.Along with development and the research and development of products of medical science, more and more multi-functional staple series products is applied to clinical.The scope of application has related to the every field such as gastrointestinal surgery, Genneral Surgery, thoracic surgery, Urology Surgery, department of obstetrics and gynecology, becomes one of requisite instrument of doctor.For patient there is less hemorrhage, less operating time in art, by apparatus, replaced manual, thereby reduce due to error that craft causes, avoid infection, postoperative function recovers the multiple advantage such as fast.
Please refer to Fig. 1, a kind of purse-string forceps, comprise device body, central shaft, cam O1, suture needle 04, moving slider 02 and card line slide block 03, when work, first tissue is placed on to suture needle 04 place, the handle of rot body, central shaft drives suture needle 04 and cam 01 to rotate, arm shaft drives suture needle 04 through tissue, the needle point of suture needle 04 is by suture needle hole, the bossing of cam O1 and moving slider 02 collision, promote moving slider 02 radially away from central shaft, thereby moving slider 02 push card line slide block 03, card line slide block 03 is moved downward, because the top in suture needle hole is provided with breach, so the needle point of suture needle 04 can catch on the suture cover of suture hole gap portions, rotation stops putting in place.Then opposite spin handle completes stitching.
In sewing process, when moving slider 02 is away from central shaft, while arriving correct position, problem due to installation accuracy, the protuberance of cam O1 leaves after moving slider 02, moving slider 02 is understood some skew, can not guarantee moving slider 02 still in position, so the situation that there will be suture needle 04 to hook less than suture.
Therefore, how guaranteeing that the suture needle of purse-string forceps can accurately hook suture, is the current technical issues that need to address of those skilled in the art.
Utility model content
The purpose of this utility model is to provide a kind of safety of purse-string forceps, and these safety can make the suture needle of purse-string forceps can accurately hook suture.Another object of the present utility model is to provide a kind of purse-string forceps that comprises above-mentioned safety.
To achieve these goals, this utility model provides a kind of safety of purse-string forceps, comprise device body and moving slider, it is characterized in that, also comprise and be arranged on described device locating part with it, described moving slider is arranged at the inside of described locating part and can slides with respect to described locating part, on described moving slider, is provided with elastic bumps.
Preferably, described elastic bumps is flexure strip.
Preferably, the inner side of described locating part is provided with and stops projection.
Preferably, described in, stop that protruding quantity is two.
Preferably, the both sides of described moving slider are provided with described elastic bumps.
Preferably, on described locating part, be provided with described elastic bumps, on described moving slider, be provided with and stop projection.
This utility model also provides a kind of purse-string forceps, comprises handle and the safety that are connected with described handle, and described safety are the safety described in above-mentioned any one.
The automatic purse-string forceps that this utility model provides, comprises device body and moving slider, also comprises and is arranged on device locating part with it, and moving slider is arranged at the inside of locating part and can slides with respect to locating part, is provided with elastic bumps on moving slider.When work, the bossing of cam and moving slider collision, promote moving slider radial motion, when moving slider moves to correct position, locating part blocks the elastic bumps of moving slider, thereby guarantee that moving slider can not move, thereby guarantee that the suture needle of purse-string forceps can accurately hook suture.

The specific embodiment
Core of the present utility model is to provide a kind of safety of purse-string forceps, and these safety can make the suture needle of purse-string forceps can accurately hook suture.Another core of the present utility model is to provide a kind of purse-string forceps that comprises above-mentioned safety.
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 2-Fig. 6, in a kind of specific embodiment, the automatic purse-string forceps that this utility model provides, comprise device body 1 and moving slider 2, also comprise the locating part 3 being arranged on device body 1, moving slider 2 is arranged at the inside of locating part 3 and can slides with respect to locating part 3, is provided with elastic bumps 21 on moving slider 2.When work, original state, as shown in Figure 5, the bossing of cam 4 and moving slider 2 collisions, promote moving slider 2 radial motions, when moving slider 2 moves to correct position, done state as shown in Figure 6, locating part 3 blocks the elastic bumps 21 of moving slider 2, thereby guarantees that moving slider 2 can not move, thereby the position of card line slide block 6 is more accurate, thereby guarantees that the suture needle 5 of purse-string forceps can accurately hook suture.
In addition, above-mentioned elastic bumps 21 is flexure strip, and the elastic restoring force of flexure strip is better, guarantees that moving slider 2 is defined.
In addition, the inner side of locating part 3 is provided with and stops projection, the elastic bumps 21 of moving slider 2 can be stuck in one end of locating part 3, when the inner side of locating part 3 is provided with while stopping projection, the elastic bumps 21 of moving slider 2 can be stuck in the inside of locating part 3, avoid linking of elastic bumps 21 and tissue, more guaranteed the safety of operation.
