Description

Technical Field

[0001] The utility model relates to the field of medical instruments, and more specifically, to a novel intestinal forceps for laparoscopic surgery. Background Art

[0002] Intestinal forceps (intestinal anastomosis forceps) are instruments used to clamp the intestinal tube. They have thin alveoli, good elasticity, and cause little damage to tissues. When in use, they can be covered with a latex tube to reduce damage to the intestinal wall.

[0003] In the prior art, a latex tube is usually put on the intestinal clamp body before use to reduce damage to the intestinal wall. However, the existing intestinal clamp usually uses the direct friction between the clamp body and the inside of the latex tube to ensure stability. Once the latex tube deviates or falls during the operation, it will affect the surgical effect and cause safety problems. At the same time, the existing intestinal clamp can usually only be fixed in one place during the clamping process, and the clamping amplitude cannot be flexibly adjusted and fixed according to different patients and usage conditions, which is inconvenient to use. For this reason, we have introduced a new intestinal clamp for laparoscopic surgery to solve the above problems. Utility Model Content
