Heart valve forming ring

Abstract

The invention discloses a heart valve forming ring which comprises a ring body, a plurality of sets of developing rings with certain elasticity are evenly arranged in the ring body, a certain distance is arranged between every two adjacent sets of developing rings, one end of the ring body is connected with a ring sleeve, one end of a contraction line is connected with the ring sleeve, and the other end of the contraction line is connected with the ring sleeve. The other end of the contraction line penetrates through the interior of the ring body and is connected with the take-up device, and the take-up device is used for controlling contraction of the ring body by tightening the contraction line. According to the device, front-back and twisting movement of the ring body is more convenient to operate, closing-up operation of the ring body is easier to carry out, closing-up operation can be achieved through a special winding mode, the risk that blood enters a macromolecule woven body after an instrument is implanted, and thrombus is increased is reduced, and the firmness between the developing ring and the ring body can be higher.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a heart valve forming ring. Background technique [0002] The incidence of mitral valve and tricuspid valve diseases remains high in adult heart valve diseases. For example, mitral regurgitation (MR) in mitral valve diseases has a very serious impact on patients. Under normal circumstances, the mitral valve in the human heart The valve acts as a hemostatic valve, preventing the return of oxygen-rich blood from the lungs to the left atrium. Once the mitral valve is improperly closed or misplaced, MR will occur, which will significantly reduce the pumping efficiency of the heart and even cause heart failure. . Mitral regurgitation is divided into two types: functional and degenerative. Functional mitral regurgitation (FMR) is characterized by mitral annulus dilatation, leaflet insufficiency, and tethered mitral valve leaflets, which are caused by Caused by left ventricular dysf...

[0002] The incidence of mitral valve and tricuspid valve diseases remains high in adult heart valve diseases. For example, mitral regurgitation (MR) in mitral valve diseases has a very serious impact on patients.

Once the mitral valve is improperly closed or misplaced, MR will occur, which will significantly reduce the pumping efficiency of the heart and even cause heart failure.

[0005] 1. The position of the ring body is not easy to control when tightening;

[0006] 2. In the process of closing the mouth, blood will enter the interior of the ring body, thereby increasing the risk of thrombus;

[0007] 3. The rigidity of the existing ring body device is relatively large, the flexibility in the body is poor, and it is not convenient to observe the position of the ring body inside the human body
