Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a balloon catheter. BACKGROUND

[0002] After the intestinal focus is removed, the two intestinal sections need to be connected by anastomosis, and the intestinal function is realized after the anastomotic stoma heals. The intestinal contents include chyme, digestive enzymes, intestinal mucus, various bacterial microorganisms and the like. If the intestinal contents are not intervened, too many contents will gather or pass through the anastomotic stoma too quickly before the anastomotic stoma heals, which may cause damage to the anastomotic stoma, and the breeding of pathogenic bacteria will cause anastomotic stoma infection, which is not conducive to the healing of the intestinal anastomotic stoma, causes anastomotic leakage, and even causes serious abdominal and pelvic infections due to the overflow of intestinal contents, threatening the life of the patient. The occurrence of anastomotic leakage has different occurrence rates due to the anastomotic site, anastomosis method, technology, patient's basic disease and the like. The occurrence rate of anastomotic leakage after rectal surgery can be as high as about 10%. Therefore, during the recovery of the anastomotic stoma, the flow direction of the intestinal contents needs to be intervened to prevent the intestinal contents from adversely affecting the recovery of the anastomotic stoma. To solve the above problems, the prior art puts a biodegradable support tube into the intestinal tract in front of the anastomotic stoma to block the intestinal contents, prevents the intestinal contents from flowing to the anastomotic stoma, and uses a drainage tube to drain the intestinal contents blocked by the support tube out of the body to achieve the purpose of protecting the anastomotic stoma. After the anastomotic stoma heals, the drainage tube is pulled out of the body, and the support tube remains in the intestinal tract and degrades by itself, without the need for a second operation to restore the stoma. It can not only reduce the pain of the patient, but also effectively prevent the excessive consumption of medical resources.

[0003] When the conventional drainage tube drains the intestinal contents, the drainage tube is fixed in the support tube by the balloon, the balloon is in contact with the intestinal contents, the balloon is easily corroded by the intestinal contents, the balloon leaks after corrosion, the sealing between the balloon and the inner wall of the support tube is reduced, and thus the intestinal contents flow out along the outer wall of the drainage tube when the drainage tube drains, polluting the anastomotic stoma. Since the balloon is located in the support tube, medical staff can only judge whether the balloon leaks according to their own experience. Due to the large difference between individuals, medical staff cannot accurately judge whether the balloon is damaged. When the drainage tube drains the intestinal contents, the intestinal contents are easily blocked in the drainage tube, so that the intestinal contents cannot be drained out of the body in time.
