Abstract

The present disclosure discloses a monoleaflet mechanical valve, which includes a mechanical valvular annulus, a limiting base, a movable valve leaflet and a guide rod; the mechanical valvular annulus is provided with a through-via in the middle; the limiting base is mounted on the bottom of the mechanical valvular annulus, and an open movement area is defined between the mechanical valvular annulus and the limiting base; both the movable valve leaflet and the guide rod are located in the movement area, the movable valve leaflet can reciprocate up and down along the trajectoy direction of the guide rod, such that the movable valve leaflet can movably open or close an entire passage opening of the through-via, so as to realize the relative increasing of the orifice area and a small transvalvular pressure gradient. According to the present disclosure, by means of the cooperation between the movable valve leaflet and the guide rod, thrombosis is effectively prevented, and the monoleaflet mechanical valve cannot be easily damaged. Even if thrombi are formed, the monoleaflet mechanical valve cannot easily get stuck, avoiding the risk of valve sticking or dysfunction, and the anticoagulant therapy can be reduced or is not needed. The mechanical valve provides a larger orifice area, significantly improving the performance of the valve, and therefore, the mechanical valve is suitable for more clinical patients, particularly patients with a small valvular annulus or underweight.
