Aortic valve root stenosis animal model

The utility model discloses an aortic valve root stenosis animal model, which comprises a valve support and a plurality of valve leaflets arranged in the valve support, and the valve support is of a meshed tubular structure capable of expanding in the radial direction and can be implanted into the aortic root of an animal through a conveying system. Calcification simulation materials capable of expanding and hardening after absorbing water are arranged on the valve stent and/or the valve leaflets. According to the utility model, a model of aortic valve stenosis of an experimental animal is simulated by utilizing the property that the calcified simulation material expands and becomes hard after absorbing water, so that the defect that the experimental animal does not have aortic lesion is made up, and a novel artificial heart valve surgical instrument can be better subjected to performance test in an animal experiment and can be improved in time. 本实用新型公开了一种主动脉瓣根部狭窄动物模型，包括瓣膜支架以及设于所述瓣膜支架内的多个瓣叶，所述瓣膜支架呈可径向扩张的网管状结构
