Abstract

The invention relates to the technical field of medical instruments, in particular to a catheter fixing device for gastrointestinal surgery. The purpose is to solve the problems of unreasonable movingmanner, limited application range and the like caused by the factors of low bidirectional moving efficiency, the failure of achieving normal direction moving, the failure of the variation of the diameter of a fixing ring and the like of an existing catheter fixing device for gastrointestinal surgery. The fixing device comprises a side enclosure fixing mechanism, a bottom bearing plate, a circumferential displacement platform, a normal direction rotary mechanism and a top fixing supporting frame. The bottom loading plate is movably connected with the bottom of the side enclosure positioning mechanism, the circumferential displacement platform is movably arranged above the bottom bearing plate, the normal direction rotary mechanism is fixedly connected with the upper surface of the circumferential displacement platform, and the top fixing supporting frame is movably connected with the top of the normal direction rotary mechanism. The fixing device has the advantages of multi-directionalpositioning, normal direction degree-of-freedom and adjustable fixing diameter.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a catheter fixer 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 t...
