Medical closed-type through-anus intestinal anastomotic stoma leak detector

Abstract

The invention relates to a medical closed-type through-anus intestinal anastomotic stoma leak detector. The leak detector comprises a tube and an air injection device, wherein the tube is provided with an air storage space; the air injection device is used for pushing air in the air storage space into an intestinal cavity; and a rubber plug in a circular truncated cone shape is arranged at an air outlet end of the tube, can be partially inserted into an anus, and is closely contacted with the anus and made of soft and elastic silica gel, so that the condition of air feed while leakage in an air feed process can be avoided, and the accurate quantity of air entering an intestinal tract and the constant intestinal cavity pressure can be guaranteed. In a leak detection process, the intestinal cavity can be kept expanding, so that the leak detection accuracy can be guaranteed, and the leak detector has higher practical values. In addition, the medical closed-type through-anus intestinal anastomotic stoma leak detector is simple in structure, ingenious in design, easy and simple to operate and capable of increasing the detection accuracy substantially.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a medical closed leak detector through anorectal anastomosis used for anorectal anastomosis or anorectal anastomosis. Background technique [0002] In colorectal surgery, a stapler is often used to anastomose the distal and proximal intestines through the anus, and the continuity and integrity of the anastomosis need to be tested after the anastomosis. The current general practice is to first clamp the intestinal tube near the anastomosis, then fill the abdominal cavity with water to submerge the anastomotic site of the intestinal tube, and then use a syringe to match the medical anal canal (or directly use a syringe) to inject air into the intestine from the anus , by observing whether there is bubble overflow at the anastomotic stoma from the abdominal cavity to judge whether there is a leak in the anastomotic stoma. Leaks require remedial action or reprocessing. However, whe...

AI Technical Summary

Problems solved by technology

However, when the patient undergoes colorectal surgery, the anal sphincter is in a relaxed state due to anesthesia, and it is difficult to anastomose with the outlet end of the syringe or the medical anal canal. Insufficient inflation of the intestinal lumen is likely to occur, and the expansion degree is not enough to detect hidden anastomotic leaks, or excessive inflation leads to tearing of the anastomotic stoma, and the leak detection effect is poor.

Especially for anastomotic leak detection in ultra-low rectal cancer radical surgery, it is very difficult
