Problems solved by technology

[0002] During interventional treatment in gastrointestinal surgery, catheters are often inserted for assistance; there are many commonly used catheters in clinical practice, such as gastric tubes, urinary catheters, body vein catheters, various surgical abdominal drainage tubes, chest tubes, etc.; medical staff When fixing catheters to patients clinically, adhesive tapes are often used to bond on the skin or directly sew them into the skin with sutures, which are prone to fall off and cause unnecessary pain to patients; and when the number of catheters implanted in the same part is large, The existing fixing methods often cause the catheters to interfere with each other and cause confusion; different catheters require different fixing angles, and the single direction of tape and suture fixing will affect the follow-up operation; therefore, there is an urgent need for a method that can be clearly classified and fixed Catheter fixation device for gastrointestinal surgery with various directions
