On the bottom inner walls of the installation grooves, winding rods are rotatably connected through bearings. Each two winding rods are jointly and drivingly connected with a forming belt with a grid-like shape on the outside. On the top of each winding rod, a clamping groove is opened. In each clamping groove, a plug is movably inserted. On the upper ends of the plugs, rotating rods are fixedly connected. The upper ends of the rotating rods pass through the operation holes and extend to the outside of the positioning rods.

[0006] Preferably, on the top ends of the rotating rods, hollow-shaped turntables are fixedly connected.

[0007] Preferably, heat pyrolysis carbon coatings are fixedly sleeved on the outside of the positioning rods.

[0008] Preferably, the positioning rods are all arranged in an arc shape and connected with the forming belt.

[0009] Preferably, the clamping grooves and the plugs are both arranged in a square shape.

[0010] Compared with the prior art, the beneficial effects of the utility model are: By arranging the winding inside the installation groove, it is convenient to rotate and adjust the length of the forming belt according to the actual situation when using the mitral valve annuloplasty ring, increasing the flexibility of use and facilitating different usage situations. At the same time, through the detachable rotating rods and plugs, it is convenient to directly take out after the surgery. With the external heat pyrolysis carbon coating, the biocompatibility and blood compatibility are increased, and the risk of thrombus formation is reduced. Description of the Drawings
