Colonic lumen series isolating membrane

Abstract

The invention relates to a medical treatment instrument and discloses a colonic lumen series isolating membrane. The isolating membrane is tubular; a first annular airbag integrally connected with the isolatingmembrane is arranged at the lower end of the isolating membrane; a second annular airbag and a longitudinal airbag are arranged on the isolating membrane; the longitudinal airbag is communicated with the first annular airbag and the second annular airbag; a connecting part is arranged at the upper end of the isolating membrane. The tubular isolating membrane has isolation and protection effects on colonic anastomotic stoma in the colonic lumen; the contents (excrements) of the colonic lumen after operation move through an isolating membrane cavity, so that the excrements are prevented from being in contact with anastomotic stoma tissues, the anastomotic stoma is effectively protected from being polluted, the tension of the excrements in the colonic lumen on the anastomotic stoma is reduced, the healing of the anastomotic stoma is facilitated, and the occurrence of anastomotic fistula is reduced; the purpose of carrying out focal excision and anastomosisin the stage I under the circumstance that the bowel preparationis in no condition to be effectively performed for complete intestinal obstruction and the like caused by emergency treatment of left colon rupture or colon tumor due to war injury is achieved.

Description

technical field [0001] The invention relates to a medical treatment instrument, in particular to a series of isolation membranes for the colon cavity. Background technique [0002] Colorectal cancer is a common malignant tumor of the digestive tract. Currently, a consensus has been reached on the choice of one-stage resection and anastomosis for emergency right colon cancer secondary intestinal obstruction, but the same one-stage resection cannot be selected for complete intestinal obstruction secondary to left colon war, trauma or cancer. anastomosis. Due to the thin intestinal wall of the left colon, poor blood supply, high bacterial content, and a large amount of semi-solid or solid content, it is difficult to remove, and most of the patients are elderly patients with weak constitution and many diseases. There are more difficulties. The methods so far dealt with are: [0003] (1) Traditional cecum or obstructed proximal colostomy: the purpose of this method is to reso...

Problems solved by technology

Disadvantages of this operation: ①Delaying the timing of radical resection of the cancer and even causing iatrogenic dissemination of the tumor, long hospital stay, increasing the incidence of abdominal surgical complications and operative mortality; pain and hospital costs

However, there are different degrees of deficiencies and complications, such as frequent diarrhea and malnutrition, falling off of placed metal stents, bleeding, perforation, etc., causing trauma and mental pain to patients
