Description

Technical Field

[0002] Portal blockade includes hepatic blood flow blockade, whole liver blood flow blockade, hepatic vein blockade, etc. Portal blockade is mainly performed during local resection of liver lesions or regular liver segment and lobe resection to reduce liver bleeding and minimize intraoperative surgical risks and the incidence of postoperative liver failure. Although portal blockade can reduce intraoperative bleeding, it may cause ischemia-reperfusion injury to liver cells, especially for patients with underlying liver disease and long blockade time. The risk of postoperative liver failure will increase significantly. Therefore, the duration of portal blockade should be controlled according to the specific situation of the liver. If the operation cannot be completed in one blockade, multiple blockades can be considered, which is safer.

[0003] 1. The most widely used laparoscopic portal obstruction device is the portal obstruction band. During operation, the doctor needs to pass the portal obstruction band around the portal part and then clamp it with a biological clamp. This is very inconvenient to use and greatly wastes the doctor's operation time. 2. Furthermore, the blocking device used for binding the portal vessels cannot support the blocking mechanism when binding the vessels, so that the blocking mechanism is not stable when binding and blocking the vessels; 3.
