Abstract

The invention relates to a mitral-valve popular type bilobed artificial heart valve, which comprises a support cage, two leaflets, and a sewing ring. The two leaflets are articulated in the support cage; the sewing ring is provided with an inner ring and sewing flange protruding outwards; the inner ring of the sewing ring is connected with the upper part of the support cage; the sewing flange is positioned in the middle part of the support cage; the lower part of the support cage is exposed. The heart valve uses only one specification to replace the existing four specifications that are 25M, 27M, 29M, and 31M, solves the mutually inconsistent problems that small installation dimension is matched with a big aperture, and is applied to all patients.

Description

technical field [0001] The invention relates to a medical device implanted in a human body, in particular to a general-purpose artificial mechanical heart valve for mitral valves. Background technique [0002] Due to the differences in the size of the hearts of different human beings, the models and specifications of the heart valves are also different. At present, there are five or six models and specifications of artificial mechanical heart valves and mitral valves in the world. There are four types of valves commonly used by adults on the market: 25M, 27M, 29M, and 31M. Many types of models and specifications have brought a lot of inconvenience to users and manufacturers. [0003] The mitral artificial mechanical heart valve is composed of a circular valve frame, two leaflets, and a suture ring. The two leaflets are hinged in the valve frame. For connecting with the valve frame, the suture flange is used for suturing with human heart tissue, the inner hoop of the suture...
