Articular gasket prosthesis and articular prosthesis with articular gasket prosthesis

An articular gasket prosthesis, comprising an elastic gasket disposed between a first skeleton and a second skeleton, wherein the first skeleton and the second skeleton form a joint, the elastic gasket comprising:

• an elastic matrix, being provided with a first contact surface facing the first skeleton and a second contact surface facing the second skeleton;
• and
• a plurality of synovial fluid passages, distributed in the elastic matrix and communicating with the first contact surface and the second contact surface, the plurality of synovial fluid passages being disposed according to a predetermined manner, so as to gradually increase a hardness of the elastic matrix from a center to an edge and gradually decrease an elasticity of the elastic matrix from the center to the edge;
• wherein the plurality of synovial fluid passages comprise a plurality of accommodation cavity layers and a plurality of flow passages, the plurality of accommodation cavity layers are disposed in a direction from the first contact surface to the second contact surface, each of the plurality of accommodation cavity layers comprises a plurality of accommodation cavities, and each of the plurality of flow passages is connected between two adjacent accommodation cavities of the plurality of accommodation cavities;
• wherein the plurality of synovial fluid passages further comprise an inflow passage, and a check valve is disposed in the inflow passage, the inflow passage is communicated with at least one accommodation cavity of the plurality of accommodation cavities, or the inflow passage is communicated with at least one flow passage of the plurality of flow passages, or the inflow passage is communicated with at least one accommodation cavity of the plurality of accommodation cavities and at least one flow passage of the plurality of flow passages.
