Implant conveying handle, implant system, conveying system and working method of conveying system

Abstract

The invention provides an implant conveying handle, an implant system, a conveying system and a working method thereof, a ratchet wheel device of the implant conveying handle comprises a convex block, a ratchet wheel and two ratchet wheel rods, and the ratchet wheel is fixed on a synchronous conveying device and used for being matched with the two ratchet wheel rods to control axial movement of an outer pipe or an inner pipe and the direction of the axial movement. Therefore, safe self-locking and transmission guiding of the outer pipe or the inner pipe are achieved. One ends of the two ratchet wheel rods are rotatably arranged on the two sides of the protruding block respectively, and the other ends of the two ratchet wheel rods are close to the ratchet wheel and used for controlling rotation of the ratchet wheel and the rotation direction during rotation; and the protruding block is rotatably arranged between the two ratchet wheel rods and used for controlling rotation of the two ratchet wheel rods, so that locking of the inner pipe and the outer pipe in the single direction is achieved, safe self-locking of the implant conveying handle is achieved, and the situation that the position of the inner pipe or the outer pipe is out of control when the inner pipe or the outer pipe is not controlled is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an implant delivery handle, an implant system, an implant delivery system and a working method thereof. Background technique [0002] Heart valves are membrane-like structures that can open and close in the organs of humans or certain animals. Each human heart has four valves: the aortic valve that connects the left ventricle to the aorta, the pulmonary valve that connects the right ventricle to the pulmonary artery, the mitral valve that connects the left atrium to the left ventricle, and the mitral valve that connects the right atrium to the right ventricle of the tricuspid valve. They both act as one-way valves, allowing blood to flow only from one direction to the other and not back. [0003] With the development of social economy and the aging of the population, the incidence of valvular heart disease has increased significantly. Studies have shown that the inciden...

Problems solved by technology

At the same time, the inaccurate operation of the delivery system will lead to operator error during the entire operation, and the positioning of the valve stent will be inaccurate, which will seriously cause serious paravalvular leakage / regurgitation and other problems in patients
