An artificial heart valve annuloplasty ring, including an outer layer (6) and an inner layer main body structure (8), the outer layer (6) is covered on the outside of the inner layer main body structure (8), and is used to be sutured to heart tissue. The inner layer main body structure (8) has a tubular helical structure formed by curling a sheet material strip, the tubular helical structure can adjust rigidity of the annuloplasty ring. The artificial heart valve annuloplasty ring has a simple structure, easily adjustable rigidity, and is easy to manufacture and process. |
