Problems solved by technology

One of the difficulties encountered in laparoscopic surgery for liver tumors is the hemostasis of blood vessels. Because the liver is fragile, the intrahepatic structure is complex, and the wall of the hepatic vein is thin. Once the hepatic vein ruptures accidentally, a large amount of CO in the pneumoperitoneum will 2 Entering the pulmonary circulation will lead

Abstract

The invention relates to the technical field of medical appliances, and provides a laparoscopic separable primary porta hepatis blocker. The block consists of a primary porta hepatis blocking clamp and a blocking clamp controller, wherein the primary porta hepatis blocking clamp consists of a pair of clamp bodies (1), a body connecting shaft (2) and a spring (3), the pair of the clamp bodies are crossly connected through the body connecting shaft, front arms (1.1) of the clamp bodies are bent like an arc shape, and rear arms (1.2) on the tails of the clamp bodies are provided with latches (1.3); the blocking clamp controller consists of a control lever and a control lever shell (4), and the control lever shell is of an L shape; and the control lever consists of a control handle (5), a first link rod (6), a second link rod (7) and a fixed shaft (8), the control handle (5) is of an L shape, and a lock hole (7.1) for connecting the latches (1.3) on the rear arms of the clamp bodies is formed on the opposite side of the second link rod (7). The laparoscopic separable primary porta hepatis blocker is convenient to use, and solves the problem of blocking blood vessel bleeding of the primary porta hepatis in a laparoscopic liver surgery.

Description

technical field [0001] The invention relates to the technical field of medical devices, and relates to a laparoscopic detachable first hepatic portal blocker used in laparoscopic hepatectomy. Background technique [0002] Clinically, surgical resection is the most effective method for the treatment of liver tumors. Conventional liver resection can reduce bleeding by using various vascular clamps and blocking bands to block the blood flow of the first hepatic hilum. However, the traditional surgical method is traumatic, with many complications and slow recovery. Colleagues at home and abroad have long placed their hopes on laparoscopic surgery to reduce trauma and speed up recovery, and have carried out arduous explorations for it. One of the difficulties encountered in laparoscopic surgery for liver tumors is the hemostasis of blood vessels. Because the liver is fragile, the intrahepatic structure is complex, and the wall of the hepatic vein is thin. Once the hepatic vein ...
