Catheter fixer for gastrointestinal surgery

Abstract

The catheter fixator comprises a bottom rod, anti-skid suction feet attached to the ground are fixed to the bottom end of the bottom rod, a horizontal limiting seat is fixed to the top end of the bottom rod, a rotating seat is rotationally connected to the interior of the limiting seat, and a mounting box is fixed to the upper surface of the rotating seat; the device comprises a mounting box, a stabilizing mechanism for fixing a guide pipe is arranged on the mounting box, two symmetrical side rods are vertically fixed to the upper surface of the mounting box, a top plate is fixed to the outer sides of the side rods, and an auxiliary mechanism for heating the guide pipe is arranged on the top plate. According to the catheter fixator for the gastrointestinal surgery department, first stabilizing assemblies in the stabilizing mechanisms are used for clamping the two sides of a catheter, clamping pieces can be limited after clamping, the situation that the stabilizing effect is affected due to the fact that a clamp moves after the catheter is stressed is avoided, and in order to further improve the stabilizing effect on the catheter, second stabilizing assemblies are used for fixing the catheter; the air bag expands after being inflated to be attached to the catheter again, so that the friction force between the air bag and the catheter is increased.

Description

technical field [0001] The invention relates to the technical field of catheter fixation, in particular to a catheter fixer for gastrointestinal surgery. Background technique [0002] With the development of science and technology, gastrointestinal surgery tends to reduce the number of traditional open surgeries, while minimally invasive gastrointestinal surgery benefits from its characteristics of small incision, strong pertinence and easy postoperative recovery. Wide range of applications, such as laparoscopic surgery, etc., the use of catheters inserted into the abdominal wall of the human body can provide a feasible operating space for laparoscopy and surgical instruments. Therefore, catheter interventional therapy is widely used in gastrointestinal surgery. Means are the basic technical prerequisites for minimally invasive surgery in gastrointestinal surgery. [0003] For example, Chinese patent CN 108310592 B discloses a dialysis catheter fixing device. The main point...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a catheter fixer for gastrointestinal surgery, which has the advantages of good fixing effect, etc., and solves the problem that when the dialysis catheter is accidentally pulled, and the pulling force is relatively large, it is very easy to get out of the clamp. The problem of disengagement in the middle
