Abstract

The invention provides a subcutaneous implantable type improved biliary tract drainage tube. The subcutaneous implantable type improved biliary tract drainage tube comprises a single-cavity drainage tube and an implantable infusion holder, and is characterized in that the implantable infusion holder is detachably connected with a first end of the single-cavity drainage tube; the single-cavity drainage tube comprises an in-vivo front section, an in-vivo middle section and an in-vivo tail section, an anti-reflux assembly for preventing reflux of bile is arranged at the in-vivo front section andcomprises two anti-reflux valves and limit parts, the anti-reflux valves are symmetrically arranged in the single-cavity drainage tube and have the same structure, and the limit parts are symmetrically arranged on the inner side wall of the single-cavity drainage tube; an anti-falling assembly for preventing I125 particles from falling off from the in-vivo tail section in a normal use process of the product is arranged at the tail end of the in-vivo tail section; and an accommodating structure capable of accommodating the I125 particles with a radiotherapy effect on tumors is also in the single-cavity drainage tube. According to the subcutaneous implantable type improved biliary tract drainage tube, the tube diameter of the drainage tube is effectively reduced by design of the single-cavity drainage tube, the drainage tube is implanted under the skin in a mode of combining the implantable infusion holder with the single-cavity drainage tube, and convenience is brought for postoperativenormal life of a patient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a subcutaneously implanted improved biliary drainage tube. Background technique [0002] Malignant obstructive jaundice is a common clinical syndrome, which includes a group of malignant tumors that cause bile duct obstruction, hilar liver cancer, cholangiocarcinoma, pancreatic cancer, ampulla cancer, and hilar lymph node metastasis, compression or invasion of the bile duct. Due to the special location of the tumor, only 5%-20% of the patients can be surgically resected. The vast majority of patients need effective biliary drainage first to reduce jaundice, and anti-tumor treatment is performed after the liver function improves. [0003] Percutaneous transhepatic biliary drainage (PTCD) is a technical means of placing a catheter in the biliary tract percutaneously and transhepatically under imaging technology. Biliary stent technology is to implant plastic or metal stents...
