Non-oblique-pulling fixed type surgical drainage tube

Abstract

The invention provides a non-oblique-pulling fixed type surgical drainage tube, belongs to the technical field of medical instruments, and aims to overcome the shortcomings of ache and even tissue necrosis and infection due to the fact sutures drag the skin after the conventional drainage tube is fixed, suture looseness and falling off as well as displacement of the drainage tube. A group of symmetric tunnel type suture holes are distributed in tube walls on two corresponding sides of the drainage tube. During use, a suture needle drags a suture to enter from the skin and the subcutaneous tissue on one side of the port site of the drainage tube, to pass through one suture hole and then to come out from the subcutaneous tissue and the skin on the other side to be knotted; the same operation is carried out on the opposite side once, and the suture is knotted to complete fixing. According to the non-oblique-pulling fixed type surgical drainage tube, a series of complications of a patient, caused by suture dragging, are avoided; the fixing effect is definite and reliable; the non-oblique-pulling fixed type surgical drainage tube is simple in structure and convenient to use, and is applicable to all parts of a human body.

Description

Technical field [0001] The invention relates to a non-oblique pull fixed surgical drainage tube, which belongs to the technical field of medical equipment. Background technique [0002] The surgical drainage tube currently used clinically is fixed to the human body in a manner similar to the cable-stayed bridge structure ( image 3 ), that is, one or two stitches are sutured on the skin beside the tube, and then the suture is tied to the drainage tube to prevent the drainage tube from shifting. However, in this case, there is often a phenomenon that the drainage tube pulls the skin through the sutures and causes obvious local pain, especially because many surgeons have never realized the problem due to their unskilled skills, and havetily rushed to the operation speed. For various reasons, the sutures are too tight when the knot is tied, causing some patients to experience severe pain that cannot be tolerated, which affects postoperative recovery and quality of life. In addition, ...
