Embodiment 1

[0031] like figure 1 , 2 As shown in , 3, an integrated biliary internal irradiation balloon drainage tube includes a double-lumen drainage tube 1 with a length of 25cm and an outer diameter of 8F (1F=0.038cm). The main cavity is the bile drainage cavity 3, which runs through the double-lumen drainage The full length of the tube 1, the auxiliary cavity is a slender internal irradiation balloon connection cavity 4, and its front end enters the internal irradiation balloon 2. The internal irradiation balloon 2 is worn outside the double-lumen drainage tube 1 with a length of 3 cm. Its front end is 5 cm away from the head of the double-lumen drainage tube 1. In the standby state, it is smooth and close to the wall of the double-lumen drainage tube 1. It is cylindrical after filling , 5mm outer diameter. An X-ray-opaque balloon mark 5 is marked on the wall of the double-lumen drainage tube 1 at both ends of the internal irradiation balloon 2 .

Abstract

The invention discloses an integrated biliary tract internal irradiation balloon drainage tube, which comprises a biliary tract drainage tube and an internal irradiation balloon. The drainage tube is characterized in that: the biliary tract drainage tube is a double-cavity drainage tube, and comprises a bile drainage cavity and an internal irradiation balloon connecting cavity next to the inner wall of the bile drainage cavity; the internal irradiation balloon is arranged on the outer wall of the double-cavity drainage tube and connected with the front end of the internal irradiation balloon connecting cavity; the outer walls of the double-cavity drainage tube on two sides of the internal irradiation balloon are provided with side holes, and the side holes are communicated with the bile drainage cavity; the front end of the double-cavity drainage tube is provided with an end hole communicated with the bile drainage cavity; the tail end of the double-cavity drainage tube is in a Y-shaped structure consisting of a straight arm and an oblique arm, the straight arm is provided with a drainage tube outer interface connected with the tail end of the double-cavity drainage tube, and the drainage tube outer interface is communicated with the bile drainage cavity; and the oblique arm is provided with an internal irradiation balloon outer interface connected with the internal irradiation balloon connecting cavity. By short-range radiotherapy in the cavities, obstructive jaundice is avoided and local tumors are effectively controlled simultaneously, and the curative effect can be improved; and the drainage tube is simple in operation, high in safety and low in expense.

Description

Technical field: [0001] The invention relates to a biliary drainage tube, in particular to an integrated biliary irradiation balloon drainage tube. Belongs to the field of medicine. Background technique: [0002] Cholangiocarcinoma is a malignant tumor of the hepatobiliary system that is difficult to treat clinically, and its incidence has been on the rise in recent years. Depending on the location of the disease, it can be divided into intrahepatic cholangiocarcinoma, hilar cholangiocarcinoma, and extrahepatic cholangiocarcinoma. Among them, hilar cholangiocarcinoma often involves the left and right hepatic ducts and the common hepatic duct at the same time, and complete surgical resection is extremely difficult. Cholangiocarcinoma grows in a variety of ways, most of which infiltrate and grow along the biliary mucosa, and can also grow into the bile duct cavity to form a polypoid mass, or infiltrate and grow around the bile duct to form an extraluminal mass. Most patients...
