Problems solved by technology

Abnormalities in any part of the mitral valve complex can cause the mitral valve to not close tightly and regurgitate
[0007] At the same time, the solutions to these problems are often contradictory
For example, in order to prevent the occurrence of paravalvular leakage and to stabilize the fixation, the circumference of the valve stent needs to be large enough to tightly adhere to the natural valve annulus, so as to eliminate or reduce the occurrence of paravalvular leakage and better fixation; A large stent will occupy the space of the left ventricular outflow tract and easily cause left ventricular outflow tract obstruction

Embodiment

[0033] Such as Figure 1-3 As shown, the present invention provides an interventional artificial heart valve, which is mainly used in implantation and replacement surgery of transcatheter mitral valve or tricuspid valve. Including valve leaflet 1, leaflet traction cable 2, valve support 3, support fixing hook 4 and support support feet 5; the valve leaflet 1 is a single-leaf leaf valve; The lower part is the ventricular segment; there is a bending structure between the atrium segment and the ventricular segment, so that the valve support 3 fits the transition area between the atrium and the ventricle, and plays the role of fixing the valve support 3; the upper part of the valve support 3 and the leaflet 1 are sutured Fixedly connected, the middle part of the valve support 3 is connected to the valve leaflet 1 through several leaflet traction cables 2, and the support foot 5 is provided at the bottom of the valve support 3; One end of the leaflet traction cable 2 is connected ...

Abstract

The invention relates to the technical field of medical instruments, in particular to an invasive artificial heart valve. The artificial heart valve comprises a valve leaf, valve leaf traction cables,a valved stent and a stent fixing hook, wherein the valve leaf is a single-leaf valve; the upper part of the valved stent is connected with the valved leaf, the middle upper part of the valved stentis connected with the valve leaf through multiple valve leaf traction cables; stent support feet are arranged at the bottom of the valved stent; and the fixing hook is located at the upper part of thevalved stent. According to the artificial heart valve, perivalvular leakage can be better prevented through redundant covering of the valve leaf, and obstruction of the outflow tract of a left ventricle is avoided; and the whole stent can be better fixed through the fixing hook and the support feet.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an interventional artificial heart valve. Background technique [0002] The heart is one of the most important organs of the human body, providing power for the blood circulation of the human body. The normal human heart has four chambers, namely the left and right atrium and the left and right ventricle. The left atrium communicates with the left ventricle, and the right atrium communicates with the right ventricle. There are valves between the atrium and ventricle to prevent the back flow of blood. The valve between the left atrium and left ventricle is the mitral valve, and the valve between the right atrium and right ventricle is the tricuspid valve. [0003] The mitral valve is located between the left atrium and the left ventricle, and acts as a one-way valve to ensure that blood flows from the left atrium into the left ventricle during diastole and does not f...
