Rectum anastomotic leakage drainage device

Abstract

The invention discloses a rectum anastomotic leakage drainage device, and belongs to the technical field of medical appliances. The rectum anastomotic leakage drainage device comprises an intestinal tract clamping drainage device and a drainage operation rod, wherein the drainage operation is rotatablely connected with the clamping drainage device; the intestinal tract clamping drainage device comprises two elastic clamping fibers and a driving bag; the two elastic clamping fingers are elastic bag bodies; a seepage membrane is arranged at the inner side of each elastic bag body; the elastic clamping fingers communicate with a negative pressure device; the driving bag communicates with a positive pressure device; before inflation, the whole of the elastic clamping fingers and the driving bag is in a long strip shape; after the inflation, the driving bag expands to be in a big semicircular ring shape; and the two elastic bag bodies are driven to be in a big semicircular shape to form a holding shape on the rectum. Under the driving effect of the driving bag, the inner side walls of the elastic clamping fingers form attaching clamping on the outer wall of the human body intestinal tract; the excretion seepage due to relative sliding of the elastic clamping fingers and the intestinal tract can be prevented; and the excretion is sufficiently adsorbed by the seepage membranes arranged at the inner sides of the elastic bag bodies and seeps into the bag body to be sucked away by the negative pressure device. Compared with the prior art, the rectum anastomotic leakage drainage device has the advantage that the drainage effect is obviously improved.

Description

Technical field [0001] The invention belongs to the technical field of medical devices, and specifically relates to a drainage device for anastomotic leakage after rectal cancer surgery. Background technique [0002] Rectal cancer is a common malignant tumor of the digestive system, and its incidence is increasing year by year. It has now become the third highest incidence tumor after lung cancer and gastric cancer. At present, it is mainly a comprehensive treatment based on surgery. In recent years, with the continuous improvement of surgical techniques, higher requirements have been placed on the efficacy and safety of surgical treatment. In the field of rectal cancer surgery, how to implement "radical resection" and ensure clinical efficacy to improve the safety of surgery It is an important issue in rectal cancer surgery to reduce the incidence of complications and reduce the incidence of "secondary operations". The most common complication of rectal cancer surgery is "anas...
