AI Technical Summary
Technical Problem
生物瓣膜主要采用猪心包或牛心包等生物组织经戊二醛交联处理制成，其血流动力学性能更接近天然瓣膜，且术后抗凝治疗周期较短，然而，生物瓣的耐久性较差，长期使用后易发生钙化、撕裂或衰败，导致患者需二次手术更换瓣膜，尤其对年轻患者影响较大
Benefits of technology
[0017]（三）有益效果：本发明提供一种榫卯结构人工心脏瓣膜将人工瓣叶嵌合在第一瓣座与第二瓣座之间，第一瓣座和第二瓣座组合在一起呈现榫卯结构，并且在瓣座上分部与下分部连接的位置设置瓣叶固定孔，通过其榫卯效应嵌合人工瓣叶，实现人工心脏瓣膜的制备，以解决现有人工心脏瓣膜对瓣叶缝合部分的干扰，造成人工瓣膜整体结构的对称性存在误差，以及难以复刻成品的问题，通过将人工瓣叶固定在瓣座底部保证了人工瓣叶的应力均匀，并且大大减轻了患者医疗负担。

Abstract
A mortise and tenon structure artificial heart valve, comprising a first valve seat body, a second valve seat body and artificial valve leaflets; the second valve seat body is arranged outside the first valve seat body, and the two are combined together by mortise and tenon structure; the artificial valve leaflets are arranged between the first valve seat body and the second valve seat body. The artificial valve leaflets are embedded between the first valve seat and the second valve seat, the first valve seat and the second valve seat are combined together to present mortise and tenon structure, and the valve leaflet fixing hole is arranged at the position where the upper part and the lower part of the valve seat are connected, the artificial valve leaflets are embedded through the mortise and tenon effect, the preparation of the artificial heart valve is realized, the interference of the existing artificial heart valve on the sewing part of the valve leaflets is solved, the error of the symmetry of the overall structure of the artificial valve is caused, and the problem that the finished product is difficult to reproduce is solved, the stress of the artificial valve leaflets is ensured to be uniform by fixing the artificial valve leaflets at the bottom of the valve seat, and the medical burden of the patient is greatly reduced.
