Needle-withdrawing and line-leading suture instrument

Abstract

The invention discloses a needle-withdrawing and line-leading suture instrument, which comprises a suture instrument shell, lifting and pulling connecting rod mechanisms, annular needles and line-leading locking mechanisms, wherein the suture instrument shell is in a cylinder-shaped structure; the lifting and pulling connecting rod mechanisms are arranged in the suture instrument shell; driving operating ends of the lifting and pulling connecting rod mechanisms are arranged at the upper part of the suture instrument shell; and driven executing ends of the lifting and pulling connecting rod mechanisms are connected with the annular needles and are arranged on a bottom plate of the suture instrument shell; a needle going bottom hole is arranged in the bottom plate of the suture instrument shell; and the line-leading locking mechanisms are arranged in positions in the periphery of the bottom plate of the suture instrument shell, which are corresponding to the annular needles. During intestinal tract rerouting surgery, the suture instrument operates the annular needles outside an abdominal cavity through the lifting and pulling connecting rod mechanisms so as to thread the needles and lead lines in lumen tissue of an abdominal wall, multiple suture lines can be simultaneously led out of a human body around a cut wound, the line leading efficiency is improved, the surgical time is shortened and surgical pain of patients is reduced, so the needle-withdrawing and line-leading suture instrument can be widely used in surgery such as intestinal tract rerouting and the like.

Description

technical field [0001] The invention belongs to medical instruments, and in particular relates to a needle-row and thread-leading suturing device suitable for suturing the abdominal wall with thread in the surgical operation of intestinal diversion. Background technique [0002] At present, in the intestinal diversion in surgical operation, when the abdominal wall stoma is punched, it is necessary to use a surgical needle to guide the skin layer, subcutaneous connective tissue membrane layer, and intra-abdominal serosa layer, so that the intestinal wall and the intestinal wall can be separated when the intestinal diversion is performed. The abdominal wall was sutured and fixed. [0003] In the process of intestinal diversion, to make a hole in the abdominal wall, it is necessary to use surgical suture needles to pass through each layer of membrane of the lead wire one by one. Because the opening of the incision is small, and after the abdominal wall is cut, the inner layer ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the problems of inconvenient operation, time-consuming and difficult operation of lead wires due to the small hole when punching holes in the abdominal wall during intestinal diversion surgery, the present invention provides a needle-leading-thread suturing device, which can be used in intestinal During the diversion operation, multiple sutures can be evenly introduced into the membrane of the abdominal cortex that needs to be threaded at one time. The operation is convenient, the threading time is short, the difficulty of the operation is reduced, and the smooth progress of the operation is ensured.
