Abstract
The utility model provides a suture device of purse-string forceps. The suture device comprises a body and a thread clamping slide block connected with the body in a sliding mode, and further comprises a fixed piece which is fixedly arranged on the body. The thread clamping slide block is provided with a connection rod which can penetrate through a hole of the fixed piece. The connection rod can be provided with an elastic piece and an adjustment piece. When the purse-string forceps are assembled, the suture device can be tested, a suture needle is rotated, if the suture needle can not be inserted in a suture needle hole, the adjustment piece on the connection rod can be adjusted to enable the suture needle hole to move, and therefore the suture needle can be accurately inserted in the suture needle hole. The utility model further provides the purse-string forceps comprising the suture device.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of stitching devices of purse-string forceps.This utility model also relates to a kind of purse-string forceps that comprises above-mentioned stitching devices.
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.Thereby for patient have less hemorrhage, less operating time in art, with apparatus replace reducing due to error that craft causes by hand, avoid infection, postoperative function recovers the multiple advantage such as fast.
As shown in Figure 1, a kind of typical purse-string forceps, comprise device body, central shaft, cam 01, suture needle, moving slider 02 and card line slide block, when work, first tissue is placed on to suture needle place, the handle of rot body, central shaft drives arm shaft and cam 01 to rotate, arm shaft drives suture needle through tissue, the needle point of suture needle is by suture needle hole, the bossing of cam 01 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 05 is provided with breach, so the needle point of suture needle 04 can catch on the suture cover of suture hole 05 gap portions, rotation stops putting in place.Then counter-rotation device body handle, because the needle point of suture needle 04 has caught on suture cover, gets back to original state so suture needle 04 can drive suture to pass tissue, then carries out next step operation.But due to the problem of machining accuracy, many times suture needle 04 cannot accurately be inserted in suture needle hole 05, thereby cannot pull out suture, cause purse-string forceps cannot normally use when operation.
Therefore, how making the suture needle of purse-string forceps accurately be inserted in suture needle hole, 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 stitching devices of purse-string forceps, and this stitching devices can make the suture needle of purse-string forceps accurately be inserted in suture needle hole.Another object of the present utility model is to provide a kind of purse-string forceps that comprises above-mentioned stitching devices.
To achieve these goals, this utility model provides a kind of stitching devices of purse-string forceps, comprise device body and the card line slide block being slidably connected with described device body, also comprise and be fixedly mounted on described device fixture with it, on described card line slide block, be provided with connecting rod, described connecting rod can, through the hole of described fixture, can arrange elastic component and regulating part on described connecting rod.
Preferably, described connecting rod is threaded rod, and described regulating part is nut.
Preferably, described connecting rod and described regulating part were tight fit.
Preferably, be provided with a plurality of spacing holes on described connecting rod, described regulating part is pin.
Preferably, described elastic component is spring.
Preferably, described elastic component is rubber blanket.
This utility model also provides a kind of purse-string forceps, comprises handle and the stitching devices being connected with described handle, and described stitching devices is the stitching devices described in above-mentioned any one.
The stitching devices of the purse-string forceps that this utility model provides, comprise device body and with the card line slide block that device body is slidably connected, also comprise and be fixedly mounted on device fixture with it, on card line slide block, be provided with connecting rod, connecting rod is positioned at the hole of fixture, is provided with elastic component and regulating part on connecting rod.When assembling purse-string forceps, can test lower stitching devices, rotate suture needle, if suture needle cannot enter suture needle hole, can regulate the regulating part on connecting rod that suture needle hole is moved, thereby suture needle is accurately inserted in suture needle hole.
