Separable air bag device for protecting intestinal tract surgery field

Abstract

The invention relates to a separable air bag device for protecting an intestinal tract surgery field. An air bag core with side holes is fixedly arranged in an air bag; an air bag plug comprises a rubber plug arranged at an air inlet of the air bag core; a sleeve type air inflation needle comprises an outer sleeve, an air inflation needle head and an air inflation pipe, and the needle head and the air inflation pipe are arranged in the outer sleeve and can move relative to the outer sleeve; the needle head is used for penetrating through the rubber plug and injecting air into the air bag; the air inflation valve comprises an injector connecting port communicated with an air inflation pipe as well as an air inflation turning bolt which can control in-out of air; and after air inflation, the air bag can be separated, the surgery field of the lower section of an intestinal tract is not influenced. The device effectively guarantees the clean and sterile state of the lower section of the intestinal tract, protects the admission passage of an orifice transluminal endoscopic surgery and protects perforation parts from being polluted in the processes of endoscopic full-thickness resection for the intestinal tract and other intestinal tract surgeries, so that sterile surgery of the lower section of the intestinal tract becomes possible, and peritonitis after the surgery can be prevented.

Description

technical field [0001] The invention relates to a medical product, in particular to a detachable gas bag device for protecting the operative field of the intestinal tract used in endoscopic minimally invasive surgery, which can effectively prevent the operative field from being polluted by feces and water. Background technique [0002] Due to the development of digestive endoscopy technology, many gastrointestinal lesions can be treated endoscopically. In some intestinal minimally invasive operations, such as endoscopic muscularis dissection (Endoscopic Muscularis Dissection, EMD), endoscopic full-thickness resection (Endoscopic Full-thickness Resection, EFR), etc., intestinal perforation may occur. Natural Orifice Transluminal Endoscopic Surgery (NOTES) is an emerging treatment method in the world in recent years. The method is to enter the abdominal cavity through the opening of the stomach wall, intestinal wall, and vaginal fornix, so that the corresponding treatment can...

AI Technical Summary

Problems solved by technology

However, due to the large amount of bacteria in the intestinal cavity and the continuous peristalsis of the intestinal tube, feces may continue to enter the operation area during the treatment process, and a large number of bacteria may enter the abdominal cavity through the opening of the intestinal wall, causing severe abdominal infection. lead to the patient's death

This is also an important reason why NOTES surgery through intestinal wall access cannot be widely carried out

[0003] However, at present, there is no device at home and abroad that can solve the problem of visual field contamination in transintestinal NOTES and other endoscopic intestinal surgery
