Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a catheter fixing device for gastrointestinal surgery. Background Art

[0002] With the development of science and technology, the number of traditional open surgeries in gastrointestinal surgery is increasingly reduced. Benefiting from its characteristics such as small incisions, strong pertinence, and easy postoperative recovery, minimally invasive gastrointestinal surgery has been widely applied. Common ones such as laparoscopic surgery use technical means of inserting thin catheters into the abdominal wall of the human body, which can provide a feasible operation space for laparoscopes and surgical instruments. Therefore, catheter intervention therapy, as a commonly used medical means in clinical gastrointestinal surgery, is the basic technical prerequisite for minimally invasive gastrointestinal surgery. In actual surgical operations, the interventional catheter needs to be maintained in the same position for a long time. At this time, a catheter fixing device is required. It is very important whether the catheter can be firmly fixed on the fixing device during use. If the catheter is not firmly fixed, it will cause the catheter to fall to the ground, affecting the use of the catheter and the treatment of patients. At the same time, the catheter that has fallen to the ground will also affect the movement of surrounding personnel.

[0003] Therefore, the utility model provides a catheter fixing device for gastrointestinal surgery. Summary of the Utility Model
