Pouch tail end tension fixing device for pouch suture

Abstract

The invention discloses a pouch tail end tension fixing device for pouch suture. The tension fixing device includes a hollow pipe for guiding a suture line, one end of the pipe is a proximal end for the suture line to pass through and stitch a pouch, the other end is a fixed segment for fixing the suture line of the sutured purse, an annular groove for accommodating the suture line is formed in the outer wall of the fixed segment, an antiskid tooth groove for winding the suture line and positioning the suture line is formed in the groove bottom of the annular groove, an outer casing is sleevedoutside the pipe in a sliding mode, an annular convex platform for limiting the outer casing is arranged on the end part of the fixed segment, an annular positioning groove is formed in the end faceof one end of the annular convex platform, an annular protrusion matching with the annular positioning groove is arranged on the end face of one end of the outer casing, and the annular protrusion ofthe outer casing is inserted into the annular positioning groove and forms positioning together with the annular convex platform. The pouch tail end tension fixing device for pouch suture is simple instructure, convenient to operate and use, and low in cost; the tension and fixing of the tail end of the pouch can be guaranteed, the stability of the pouch is improved, and the occupied space is less.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a purse-string tail tension fixing device for purse-string suture. Background technique [0002] The development of cardiac surgery has a history of nearly 100 years, and it has been developed for more than half a century in our country. Although with the advancement of science and technology, the invention of various advanced instruments, minimally invasive surgery, robotic surgery, cardiac assist devices, etc. , is innovating all the time, but the most basic cardiac operation technology is still widely used in the world with its irreplaceable position, among which the purse-string suture of the arterial system is a basic skill that every cardiac surgeon must master, and the purse-string suture is for preset How to fix the sutures is also a relatively basic but important problem at present. Inaccurate fixation is likely to cause all previous efforts to be wasted. Poor fixation of ...

[0002] The development of cardiac surgery has a history of nearly 100 years, and it has been developed for more than half a century in our country. Although with the advancement of science and technology, the invention of various advanced instruments, minimally invasive surgery, robotic surgery, cardiac assist devices, etc. , is innovating all the time, but the most basic cardiac operation technology is still widely used in the world with its irreplaceable position, among which the purse-string suture of the arterial system is a basic skill that every cardiac surgeon must master, and the purse-string suture is for preset How to fix the sutures is also a relatively basic but important problem at present. Inaccurate fixation is likely to cause all previous efforts to be wasted. Poor fixation of the finally sutured purse may cause tearing and bleeding. The traditional fixation technique uses fixation forceps, not only The tension is not easy to control, and it takes up a lot of space, which adds a lot of trouble to the already cramped surgical field
