Circular purse-string forceps capable of automatically sewing in purse way

Abstract

The invention relates to a pair of circular purse-string forceps capable of automatically sewing in a purse way, which comprises a fixed forceps body, a movable forceps body, a suture needle component and a suture needle drive device, wherein the fixed forceps body comprises a fixed handle and a fixed head part; an arc-shaped tooth-shaped edge is arranged at one side of the fixed head part; the movable forceps body comprises a handle part, a fork-shaped part and an arc-shaped head part; the arc-shaped head part is provided with a tooth-shaped structure capable of being closed with the fixed head part; the fixed handle of the fixed forceps body passes through the fork-shaped part of the movable forceps body and is rotationally connected with the fork-shaped part of the movable forceps body through a fixed pin; an annular suture needle sliding groove is arranged in a purse-string forceps head part formed by closing the fixed head part of the fixed forceps body and the arc-shaped head part of the movable forceps body; the suture needle component is installed in the annular suture needle sliding groove; and the suture needle drive device passes through the fixed handle of the fixed forceps body along the axial direction, and the head part of the suture needle drive device drives the suture needle component to move around the annular suture needle sliding groove. The circular purse-string forceps have the beneficial effects that a proper amount of tissues at the purse can be ensured, and the sewing in a purse way can be automatically, conveniently and reliably ensured.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a circular purse forceps capable of automatically punching purses. Background technique [0002] In surgical operations, since the invention of the first staple product in the 1960s, medical staplers have become an indispensable medical device in the process of assisting incision sutures. [0003] With the development of medicine and the research and development of medical device products, more and more staple products are used in clinical practice. The scope of application of such products has involved gastrointestinal surgery, hepatobiliary surgery, thoracic surgery, urology, obstetrics and gynecology and other fields, and has become one of the indispensable tools for doctors. For patients, the application of such tools has the advantages of less intraoperative blood loss and shorter operation time, and the use of instruments instead of manual labor can reduce errors and inf...

AI Technical Summary

Problems solved by technology

This instrument has great disadvantages for rectal resection or esophagectomy and other limited surgical sites: firstly, the purse string can only be pulled along the transverse section of organ tissue, which requires a suitable operating space, otherwise it is easy The oblique force causes the staples to separate from the tissue, resulting in the failure of the purse bag. For the part with limited position, it is impossible to have a suitable operating space, so the risk of surgery in this kind of part is extremely high; Excessive pulling force may cause the staples to fall into the human body. Due to the limited position and the small size of the staples, it is not easy to find the fallen staples, which may eventually cause the staples to remain in the human body, which may pose a life-threatening threat to the patient.
