| titleOfInvention | Combined fully organic high molecular material artificial knee joint |
| abstract | A combined fully organic high molecular material artificial knee joint, comprising a femur condyle (2), a tibia holder (4) and a tibia liner (3), the femur condyle (2) and the tibia holder (4) being formed by polyether ether ketone (PEEK) or derivatives thereof, and the tibia liner (3) being formed by ultra-high molecular weight polyethylene (UHMWPE). The tibia holder (4) comprises a platform (6) and a stable wing positioning portion (5) vertical thereto; upper and lower ends of the tibia liner (3) are jointed with the femur condyle (2) and the platform (6) respectively; the femur condyle (2) buffers a slide surface of the tibia liner (3); and the tibia holder (4) can finely move relative to a fixed surface of the tibia liner (3), and buffering of the femur condyle (2) against the slide surface of the tibia liner (3) matches fine movement of the tibia holder (4) relative to the tibia liner (3). Main parts of all implant components of the artificial knee joint are formed by high molecular materials, thereby relieving allergy and toxicity problems probably caused by metal and metal corrosion; PEEK elastic modulus matches a natural bone, thereby relieving a stress shield problem; a wearing problem is greatly relieved by means of the combination of buffering of the PEEK femur condyle (2) against the slide surface of the UHMWPE tibia liner (3) and fine movement of the tibia holder (4) relative to the fixed surface of the UHMWPE tibia liner (3); and meanwhile, by adding enhancement and developing components, the practicality is further improved. |
