Tricuspid valve edge-to-edge clip device capable of being implanted through catheter

Abstract

The invention relates to a tricuspid valve edge-to-edge clip device capable of being implanted through a catheter. The tricuspid valve edge-to-edge clip device comprises a rotating propelling operating rod, a main body support threaded rod and a nickel-titanium alloy dish-shaped dish, wherein the rotating propelling operating rod covers outside a connecting pushing rod, the connecting pushing rod is connected with the main body support threaded rod arranged under the connecting pushing rod through a cylindrical pin arranged at the lower end of the connecting pushing rod, the external side of the main body support threaded rod is in sleeved connection with a rotating support mechanism, connecting rods extending out of two sides of the rotating support mechanism are respectively connected with needle plates on the tricuspid valve arranged at two sides, the lower ends of the needle plates on tricuspid valve is connected with the lower end of the main body support threaded rod, two sides of the lower end of the main body support threaded rod are symmetrically connected with and provided with an outwards-extended base plate under the tricuspid valve, and the middle of the base plate under the tricuspid valve is fixed with the elliptic nickel-titanium alloy dish-shaped dish in a clamping way. The tricuspid valve edge-to-edge clip device is simple in structure, good in biocompatibility and tracing performance, good in mechanical support force, good in compliance and shape memory ability, and has little wound to patients in use.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an edge-to-edge clamping device for a tricuspid valve that can be implanted through a catheter. Background technique [0002] Cardiovascular disease is currently the number one killer of human health, and heart valve disease accounts for a very large proportion. Common valvular diseases include functional and structural abnormalities of single or multiple valvular structures. In the past, people paid more attention to aortic valve and mitral valve diseases, and new treatment methods emerged one after another, effectively treating a large number of valve patients. With the deepening of people's understanding of valvular disease, more and more attention has been paid to tricuspid valve disease, especially for heart failure caused by tricuspid regurgitation. Hot issues in the research field. [0003] The anatomy of the tricuspid valve includes the annulus, leaflets, chordae and...

AI Technical Summary

Problems solved by technology

[0004] At present, the treatment of tricuspid regurgitation is still dominated by tricuspid annuloplasty. Tricuspid valve replacement is not only likely to cause conduction block, but the long-term effect is poor, and the mechanical valve also involves postoperative anticoagulation, etc. Inconvenient, so less clinical application

Different from the treatment of mitral valve insufficiency, there are many treatment methods for tricuspid valve insufficiency, but at present, none of them is recognized as the most ideal method
