Abstract

The invention belongs to the technical field of medical instruments, and especially relates to a pressure selective hepatic inflow occlusion apparatus which comprises a movable end, a fixed end, a pressure transducer, a controller and a display screen, wherein the movable end is provided with a deformable hollow U-shaped ring, the fixed end controls the contraction and expansion of the two sidewalls of the hollow U-shaped ring through a regulating part, the pressure transducer is arranged on the inner bottom of the hollow U-shaped ring, and the pressure transducer and the display screen are electrically connected with the controller. The pressure selective hepatic inflow occlusion apparatus is delicate in design and convenient to control and can quantitatively occlude different blood vessels of a hepatic portal according to pressure.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular to a pressure selective hepatic port blocking device. Background technique [0002] Many hepatobiliary diseases require hepatectomy to remove liver lesions. Primary hepatobiliary benign and malignant tumors or secondary liver tumors are the most common indications for liver resection. Part of cystic dilatation of the bile duct, benign biliary stricture and liver trauma also require hepatectomy. [0003] The blood supply to the liver is very rich. The blood flow into the liver mainly passes through the Glisson system (the tube system in the liver), which contains the portal vein, hepatic artery, and hepatic bile duct. The three are enclosed in a connective tissue sheath called Glisson sheath. Enter the liver parenchyma at the first hepatic portal. [0004] Bleeding and blood transfusion are one of the main causes of complications and even death after hepatectomy. Effective...
