Abstract

The invention relates to an internal and external drainage tube for advanced liver cancer. The internal and external drainage tube comprises a COOK drainage catheter body (1) and is characterized in that the COOK drainage catheter body (1) comprises a bile-duct drainage part (2) extending into the bile duct during use, a liver drainage part (3) located in the liver during use and an in-vitro outerpart (4). The internal and external drainage tube has the advantages that the double drainage manner sequentially performing internal drainage and external drainage is adopted, safety can be guaranteed to the maximum extent, the external drainage can be used even if the internal drainage is forced to stop, and external drainage time is reduced; meanwhile, an self-overflow guide device is used, drainage failure caused by the fact the excessive effusion cannot be discharged when the internal drainage is forced to stop and the external drainage is not started, and problems in the prior art are well solved.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic medical interventional ultrasonic minimally invasive surgery medical equipment in clinical medicine, and specifically relates to a percutaneous transhepatic intrahepatic bile duct internal and external drainage tube for end-stage cholangiocarcinoma. Background technique [0002] End-stage hepatic cholangiocarcinoma can no longer be surgically removed, and the tumor causes severe biliary obstruction, cholestasis, liver function damage and other symptoms that seriously endanger the lives of patients and reduce the quality of life of patients with advanced cancer. In the past, the COOK tube used for percutaneous transhepatic intrahepatic bile duct drainage under the guidance of ultrasound only had a curved catheter with a diameter of 2 cm (with 5 side holes) at the front end of the catheter. Drainage to relieve a series of symptoms such as obstructive jaundice caused by cholestasis. However, long...
