Catheter fixing device for gastrointestinal surgery

Abstract

The invention relates to the field of medical appliances and particularly relates to a catheter fixing device for gastrointestinal surgery. The catheter fixing device comprises a mounting plate and bearings, wherein fixing components are separately arranged at the left and right sides of the mounting plate, a snapping groove is formed in the front part of the top end of the mounting plate, a C-shaped sliding groove is formed in the rear end of the inner side of the mounting plate, the left and right sides of the C-shaped sliding groove are in sliding connection with L-shaped sliders separately, rear ends of the L-shaped sliders are in threaded connection with screw rods, left ends of the screw rods are rotatably connected to the sidewall of the left end of the C-shaped sliding groove through the bearings, right ends of the screw rods are fixedly connected with turn knobs, a rectangular slide opening is formed in the top of the front end of the C-shaped sliding groove, a rectangular sliding groove is formed in the middle part of the top end of the mounting plate, clamping blocks are fixedly connected to top ends of the L-shaped sliders, and rectangular slide openings are in slip connection with upper ends of the L-shaped sliders. The catheter fixing device for the gastrointestinal surgery, provided by the invention, is good in fixing effect and convenient to disassemble.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a catheter fixing device for gastrointestinal surgery. Background technique [0002] With the development of science and technology, the clinical practice of gastrointestinal surgery tends to reduce the number of traditional open operations, and the minimally invasive surgery of gastrointestinal surgery benefits from its small wound, strong pertinence, and easy postoperative recovery. Wide range of applications. Common techniques such as laparoscopic surgery, etc., use thin catheters to insert into the abdominal wall of the human body, which can provide a feasible operating space for laparoscopes and surgical instruments. Therefore, catheter interventional therapy, as a commonly used medical method in clinical gastrointestinal surgery, is the basic technical premise of minimally invasive gastrointestinal surgery. However, in actual operation, the interventional catheter needs...

Problems solved by technology

[0003] However, when the existing catheter fixing device fixes the catheter, it cannot be disassembled more conveniently, nor can it be installed conveniently and quickly, nor can it prevent the catheter from moving more effectively when fixing the catheter, and prevent the increase of the distance between the wound and the catheter. Friction, which increases patient pain and prolongs wound healing
