Embodiment Construction

[0042] The core idea of ​​the present invention is that, in the first aspect, an implant delivery handle is provided, which includes two delivery subsystems arranged along the axial direction of the catheter assembly, and the delivery subsystem at the distal end is connected to the outer tube of the catheter assembly. the proximal end of the tube at which the delivery subsystem is connected to the proximal end of the inner tube of the catheter assembly;

[0043] Wherein, the transmission subsystem includes a synchronous transmission device and a ratchet device, the ratchet device is fixed on the synchronous transmission device, and is used for safety self-locking of the outer tube or the inner tube through the synchronous transmission device and transmission guides.

[0044] In a second aspect, an implant delivery system is provided, including the implant delivery handle, and a catheter assembly, the catheter assembly includes an outer tube and an inner tube that are sequentia...

Abstract

The invention provides an implant conveying handle, an implant system, a conveying system and a working method of the conveying system. The implant conveying handle comprises two conveying subsystems arranged in the axial direction of a catheter assembly, and the conveying subsystem located at the far end is connected with the near end of an outer tube of the catheter assembly; the delivery subsystem located at the near end is connected with the near end of an inner tube of the catheter assembly; each conveying subsystem comprises synchronous conveying devices and ratchet wheel devices, wherein each ratchet wheel device is fixed on the corresponding synchronous conveying device and is used for carrying out safe self-locking and transmission guiding on the outer tube or the inner tube through the corresponding synchronous conveying device so as to realize locking of the inner tube and the outer tube in a single direction; and reverse movement of the inner tube or the outer tube caused by misoperation of an operator is avoided, safe self-locking of the implant conveying handle is achieved, and the inner tube or the outer tube is prevented from being out of control at an uncontrolled position.

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...
