Description

Hemostatic forceps for hepatobiliary surgery

Technical Field

The invention relates to the technical field of medical instruments, and particularly belongs to a pair of hemostatic forceps for hepatobiliary surgery.

Background

In hepatobiliary surgery, because of unique dual blood supply of hepatic artery and portal vein, blood circulation is extremely rich, the difficulty of hepatectomy is high, hemorrhage of different degrees can occur in the operation and after the operation, and the amount of bleeding is positively correlated with the incidence rate and the fatality rate of postoperative complications. Controlling and reducing the bleeding of a hepatectomy procedure is an important measure to reduce the incidence of postoperative complications and the mortality of the procedure.

In the hepatectomy operation, need cut off blood vessels such as hepatic artery, at first ligate the blood vessel and block and cut off again, avoid losing a large amount of blood, at present when ligate the blood vessel and block, do not stabilize in vivo, block to form certain influence to the blood vessel, locking operation between the claw beam of present hemostatic forceps is comparatively complicated and inconvenient.
