Abstract

The invention provides an artificial tibia prosthesis and an artificial knee joint, which relate to the technical field of medical instruments, the artificial tibia prosthesis comprises a tibia support, a tibia liner and a connecting part; the tibia liner is clamped on the tibia support; the tibia liner is limited to move away from the tibia support; meanwhile, the connecting part extends into a limiting groove defined between the tibia support and the tibia liner; the resistance for preventing the tibia liner from sliding relative to the tibia support is formed; further, the tibia liner is fixed on the tibia support; the problem that in the prior art, a locking structure between the tibia support and the tibia liner is complex is solved. The technical problems that connection between thetibia support and the tibia liner is weakened through the thin wall and the thin groove, the abrasion is caused after long-time use, and the service life is short are solved, and the technical effectsthat the locking structure between the tibia support and the tibia liner is simplified, and the service life is effectively prolonged are achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an artificial tibial prosthesis and an artificial knee joint. Background technique [0002] The so-called internal prosthesis of the knee joint includes two parts: the femoral prosthesis and the tibial prosthesis. Among them, the femoral prosthesis is connected to the distal end of the femur through a femoral mounting stem or screws, and has inner and outer condyles. The tibial prosthesis is divided into two parts: tibial liner and tibial rest. The tibial rest is fixed on the proximal end of the tibia. The tibial liner is located between the femoral prosthesis and the tibial rest. It can be translated or rotated on the tibial rest. The articular surfaces of the condyles are matched with the articular surfaces of the inner and outer condyles of the femoral prosthesis to simulate the normal human natural knee joint movement process. [0003] The locking mechanism of the m...
