Abstract

The invention relates to a chain type hepatic blood vessel blocker. The chain type hepatic blood vessel blocker comprises a connecting piece I, a connecting piece II, a fixing plate I and a fixing plate II, wherein a plurality of joints are movably connected to form the fixing plate I, a plurality of joints are movably connected to form the fixing plate II, the fixing plate I and the fixing plate II can rotate in the same plane and are arranged in parallel in the perpendicular direction, the connecting piece I is arranged in the middle of the fixing plate I and in the middle of the fixing plate II in a sleeved mode, the fixing plate I is connected with the fixing plate II through the connecting piece I, one end of the connecting piece II is arranged at the tail end of the fixing plate I, the other end of the connecting piece II is arranged at the tail end of the fixing plate II, and the tail end of the fixing plate I is connected with the tail end of the fixing plate II through the connecting piece II. The chain type hepatic blood vessel blocker is simple in structure, the two fixing plates can be directly used for clamping the liver in the regular or irregular liver resection operation, force is evenly exerted on the surface of the liver, and the chain type hepatic blood vessel blocker is convenient to operate in the operation process. The two fixing plates can be placed to form various geometric figures, the blood vessels of the portal system and the blood vessels of the hepatic vein system can be blocked at the same time, and therefore normal blood circulation of the hepatic tissue can be ensured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a chain-type hepatic vessel blocker especially suitable for liver operations. Background technique [0002] Liver surgery is divided into regular and irregular liver resection. Since the liver has two blood vessels entering the liver (portal system) and exiting the liver (hepatic venous system), the blood supply of the liver is extremely rich, and bleeding is easy to occur during surgery. The blood supply to the healthy liver will cause hemodynamic changes and reperfusion injury. Intermittent blockade during the operation also causes bleeding, which brings inconvenience to the operation. [0003] However, hemihepatic blood flow occlusion is the most commonly used at present, which largely guarantees the blood supply to the healthy side without intermittent blood flow occlusion. In the hepatic blood flow occlusion, the right or left half of Green's system was selected, ...
