Abstract
The stitching devices of purse-string forceps provided by the invention, 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, card line slide block is provided with connecting rod, connecting rod through the hole of fixture, connecting rod can arrange elastic component and regulating part.When assembling purse-string forceps, lower stitching devices can be tested, rotating suture needle, if suture needle cannot enter suture needle hole, then the regulating part on connecting rod can be regulated to move to make suture needle hole, thus suture needle is accurately inserted in suture needle hole.The present invention also provides a kind of purse-string forceps comprising this stitching devices.
Description
Technical field
The present invention relates to technical field of medical instruments, particularly a kind of stitching devices of purse-string forceps.The invention still further relates to a kind of purse-string forceps comprising above-mentioned stitching devices.
Background technology
In medical science applied surgical operation, since 20th century invention sixties first staple series products, Medical stapler has become the requisite a kind of medical apparatus and instruments aided 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 have less hemorrhage, less operating time in art, with apparatus replace manual thus reduce cause due to craft error, 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, operationally, first tissue is placed on suture needle place, the handle of rot body, centre axis movable pendulum arm axle and cam 01 rotate, arm shaft drives suture needle through tissue, the needle point of suture needle is by suture needle hole, bossing and the moving slider 02 of cam 01 collide, promote moving slider 02 radial direction away from central shaft, thus 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 stopping puts in place.Then counter-rotation device body handle, because the needle point of suture needle 04 has caught on suture cover, so suture needle 04 can drive suture to pass tissue get back to original state, 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, thus cannot pull out suture, purse-string forceps is caused cannot normally to use when performing the 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.
Summary of the invention
The object of this invention is to provide a kind of stitching devices of purse-string forceps, this stitching devices can make the suture needle of purse-string forceps can accurately be inserted in suture needle hole.Another object of the present invention is to provide a kind of purse-string forceps comprising above-mentioned stitching devices.
To achieve these goals, the invention provides a kind of stitching devices of purse-string forceps, the card line slide block comprising device body and be slidably connected with described device body, also comprise and be fixedly mounted on described device fixture with it, described card line slide block is provided with connecting rod, described connecting rod through the hole of described fixture, described connecting rod can arrange elastic component and regulating part.
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, described connecting rod is provided with multiple spacing hole, described regulating part is pin.
Preferably, described elastic component is spring.
Preferably, described elastic component is rubber blanket.
Present invention also offers a kind of purse-string forceps, the stitching devices comprising handle and be connected with described handle, described stitching devices is the stitching devices described in above-mentioned any one.
The stitching devices of purse-string forceps provided by the invention, 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, card line slide block is provided with connecting rod, connecting rod is positioned at the hole of fixture, connecting rod is provided with elastic component and regulating part.When assembling purse-string forceps, lower stitching devices can be tested, rotating suture needle, if suture needle cannot enter suture needle hole, then the regulating part on connecting rod can be regulated to move to make suture needle hole, thus suture needle is accurately inserted in suture needle hole.

Detailed description of the invention
Core of the present invention 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 can accurately be inserted in suture needle hole.Another core of the present invention is to provide a kind of purse-string forceps comprising above-mentioned stitching devices.
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 2-Fig. 4, in a kind of detailed description of the invention, the stitching devices of purse-string forceps provided by the invention, the card line slide block 4 comprising device body 1 and be slidably connected with device body 1, also comprise the fixture 8 be fixedly mounted on device body 1, card line slide block 4 is provided with connecting rod 42, and connecting rod 42 is positioned at the hole of fixture 8, connecting rod 42 is provided with elastic component 5 and regulating part 6.When assembling purse-string forceps, lower stitching devices can be tested, rotating cam 2, thus moving slider 3 drives card line slide block 4, suture needle 7 is simultaneously rotated, if suture needle 7 cannot enter suture needle hole 41, then the regulating part 6 on connecting rod 42 can be regulated to move to make suture needle hole 41, thus suture needle 7 is accurately inserted in suture needle hole 41.
In addition, connecting rod 42 is threaded rod, and regulating part 6 is nut, and the precision that nut regulates is higher, can more easily regulate card line slide block 4.
