DUCT STENT BEING CAPABLE OF CARRYING THE SUBMINIATURE RADIOACTIVE PARTICLE SOURCE |
摘要 |
A duct stent being capable of carrying the subminiature radioactive particle source is mainly used for the inside radiation therapy of metaphase or terminal pancreatic cancer and bile duct cancer, and has drainage function. The duct stent consists of a tubular drainage tube (1) and fixation portions (2) which are face to face with two ends of the drainage tube (1) and can fix the stent to prevent the stent from moving. The lumen of the drainage tube (1) is a drainage cavity (1.1) for draining the pancreatic juice or the bile. A particle passage (1.2) is provided in the tube wall of the drainage tube (1). The inside diameter of the particle passage (1.2) matches with the outer diameter of the subminiature radioactive particle source. |
