A subcutaneously implanted biliary drainage tube

Abstract

A subcutaneous implantable biliary drainage tube, which includes a single-lumen drainage tube and an implanted infusion stand; it is characterized in that the implantable infusion set is detachably connected to the first end of the single-lumen drainage tube; the single-lumen drainage tube Including the front part, the middle part and the tail part of the body, an anti-reflux component is set in the front part of the body to avoid bile reflux. The stopper is set on the inner wall of the single-lumen drainage tube; the end of the tail section in the body is provided with an anti-falling component that prevents the I125 particles from falling off from the tail section of the body during normal use; the single-lumen drainage tube is also set to accommodate The containment structure of I125 particles for tumor radiotherapy; the invention effectively reduces the diameter of the drainage tube by designing a single-lumen drainage tube, and embeds the drainage tube by combining the implantable infusion stand and the single-lumen drainage tube Under the skin, it is convenient for patients to live a normal life after surgery.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a subcutaneously implanted 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 at the s...
