Abstract

The invention provides a porta hepatis blocking belt, and relates to the technical field of medical instruments. The porta hepatis blocking belt comprises a belt body, a fixing hole and a releasing hole are formed in the belt body, and the fixing hole is communicated with the releasing hole; a damping hole is formed in the outer wall of the belt body, and a damping protrusion matched with the damping hole is arranged on the inner wall of the fixing hole. The connecting section on the belt body can be in interference fit with the fixing hole, and the connecting section on the belt body can be in clearance fit with the relieving hole. The technical effect that the hepatic portal blocking belt is convenient to remove is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a hepatic portal blocking band. Background technique [0002] There are many types of hilar occlusion clinically, including hepatic inflow occlusion, hepatic blood flow occlusion, and hepatic vein occlusion. Portal hepatic occlusion is mainly used in liver surgery, especially in liver surgery where surgical resection is estimated to be very difficult and intraoperative blood loss is large. The anatomical structure of the liver can be observed more clearly through the hepatic portal block, which is beneficial to the treatment of the intrahepatic bile duct and blood vessels. It can not only speed up the operation speed, but also minimize the risk and bleeding during the operation, and reduce the incidence of postoperative bile leakage and liver failure. Although occlusion of the hepatic portal has a very good effect on surgical operations, the intrahepatic blood perfusion...
