[0002] Hepatobiliary surgery is also clinically known as hepatobiliary, spleen, and pancreatic surgery. Diseases covered include diseases of the liver and bile duct, such as hemangiomas and primary liver tumors. It also includes the diagnosis and treatment of gallbladder stones and inflammation, as well as biliary tumors, common bile duct stones, and congenital cystic dilatation of the common bile duct.
[0003] Drainage tubes are used when needed in hepatobiliary surgery. The purpose of using drainage tubes is to smoothly drain the fluid accumulated in the body cavity to ensure the cure of the patient's disease. Therefore, the patency of the drainage tube is very important. Because the drainage tube is a soft catheter made of medical silicone, one end of the drainage tube needs to be connected to the drainage bag. Since the drainage bag is always perpendicular to the bottom surface, it is convenient to observe the amount of discharged fluid. However, when the patient stands or lies flat, the angle between the drainage tube and the drainage bag will change accordingly, which cannot be well adapted to the different body positions of the patient, causing blockage and affecting the discharge of accumulated fluid. The present application proposes an anti-bending clamping structure for the drainage tube. Summary of the Invention
