Laparoscopic hepatic portal occlusion device and application method

Abstract

The invention discloses a laparoscopic hepatic portal occlusion device and an application method. The laparoscopic hepatic portal occlusion device comprises a fixing barrel, wherein the top of an inner wall of the fixing barrel is rotationally connected with an outer screw barrel through a bearing; the top of the outer screw barrel is fixedly connected with a knob; through grooves are formed in the top, close to the left side and the right side, of the fixing barrel; the inner wall of each through groove is connected with a moving rod in a sliding manner; and the surface of the outer screw barrel is in threaded connection with a push-pull assembly for driving the moving rods to move from left to right. Through cooperation of the structures, a blocking band can be simply and quickly clampedand fixed through rotating the knob after being preliminarily clamped, clamping and fixing are firmer, a clamping assembly moves upwards by rotating a screw after the blocking band is clamped and fixed, and the blocking band contracts, so that hepatic portal occlusion is achieved, the operation process is relatively simple and convenient and convenience is provided for surgical operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a laparoscopic hepatic portal blocking device and an application method. Background technique [0002] Hepatectomy is the most important treatment method for diseases such as liver cancer, hepatic hemangioma, and benign liver tumors. my country is a big country for liver cancer, and tens of thousands of patients need liver resection every year. Laparoscopic surgery has gradually become the preferred method for liver resection because of its less trauma, fewer complications, and faster recovery. However, laparoscopic surgery has disadvantages such as small operating space and less flexible operation of instruments than manual operation. Therefore, the innovation and development of surgical devices is particularly important, which will help improve the efficiency and effectiveness of laparoscopic surgery. [0003] Hepatic portal block is an essential core link in liver r...

Problems solved by technology

This traditional method is time-consuming and labor-intensive, with many parts and steps, and difficult operation (thin and soft mousse threads are often difficult to pass through long plastic sleeves). Due to manual errors, the hepatic hilum blocking force cannot be kept consistent, which may easily cause unnecessary bleeding and biliary fistula during the operation. Therefore, we propose a laparoscopic hepatic hilar blocking device.
