Abstract

The invention relates to a degradable intestinal tract complete flow transporting stent. The degradable intestinal tract complete flow transporting stent comprises an intestinal tract fixing part 1, wherein the intestinal tract fixing part 1 comprises a circular tube 11 for forming intestinal cut crawling matching sections on two sides; loudspeaker-shaped openings 12 which are gradually extended are respectively connected to two ends of the circular tube 11; and convex rings 13 for binding the intestine breaking end are respectively arranged adjacent to the corresponding loudspeaker-shaped openings 12, of the circular tube 11. The degradable intestinal tract complete flow transporting stent is characterized in that a separating diaphragm 2 for separating a hollow inner cavity is arranged in a hollow inner cavity in the circular tube 11; and the intestinal tract fixing part 1 and the separating diaphragm 2 are manufactured by degradable materials having biocompatibility. The degradableintestinal tract complete flow transporting stent disclosed by the invention cooperates with a drainage tube for usage, so that intestinal tract complete flow transporting can be realized, a secondarysurgery of stoma return is not needed, the infection risk is not generated, and the degradable intestinal tract complete flow transporting stent can be developed in X-ray examination or CT examination.

Description

technical field

[0001] The invention relates to a degradable intestinal complete diversion support, which is used for assisting a drainage tube to complete intestinal complete diversion.

[0002] technical background

[0003] After colorectal surgery, anastomotic leakage is a common complication, with an incidence rate of about 2%-20%. After resection of intestinal lesions, the broken ends of the intestinal tract need to be anastomosed to restore its continuity. If the intestinal anastomosis is not healed well, anastomotic leakage occurs, and the contents of the intestinal tract flow into the abdominal cavity, which may cause infection in the abdominal cavity or even the whole body. In severe cases Cause septic shock and even death. According to literature reports, the incidence of anastomotic leakage after colorectal surgery is about 2%-20%, and the lower the position of the anastomosis (closer to the anus), the higher the incidence of anastomotic leakage. Anastomotic leak...
