Abstract

Provided is an artificial on-ring mechanical valve for replacing a bicuspid valve membrane. The artificial on-ring mechanical valve is used for being implanted into the heart to replace the cardiac bicuspid valve membrane which is positioned on the junction of the left atrium and the left ventriculus and has a lesion. The artificial on-ring mechanical valve includes a valve stent, a pair of openable valve leaflets and a suturing ring, wherein the valve stent includes a tubular part matched with a bicuspid valve ring in the left ventriculus, the valve leaflets are installed on the valve stent,contained in the tubular part and used for controlling one-way circulation of blood, and the suturing ring is fixed to the tubular part and used for being sutured with the bicuspid valve ring. The tubular part is also provided with an inflow end opening part and an outflow end opening part for blood to flow from the left atrium into the left ventriculus, and the suturing ring is arranged on the outflow end opening part.

Description

technical field [0001] The invention relates to an artificial mechanical valve, in particular to an annulus mechanical valve used for replacing a mitral valve. Background technique [0002] Heart valves include mitral valve, tricuspid valve, aortic valve and pulmonary valve. The mitral valve is located between the left atrium and left ventricle, and is used to ensure the one-way flow of blood from the left atrium to the left ventricle. Mitral valve disease is one of the common heart valve diseases, and its etiology includes rheumatic, degenerative and infective endocarditis, etc. Mitral valve mechanical valve replacement is a common treatment for heart mitral valve disease . [0003] The mitral valve includes leaflets, valve ring, chordae, papillary muscles and the left ventricular wall attached to the papillary muscles. During valve replacement, how to deal with the diseased valve will directly affect the prognosis and recovery of the patient. In order to implant an artif...
