Problems solved by technology

Knee joint prosthesis usually includes a femoral component, a spacer and a tibial component. At present, the domestic knee joint prosthesis structure needs to use bone cement as the medium between the bone and the prosthesis to tightly connect and fix the two together. Bone cement itself has a fatal bone cement

Abstract

A knee joint prosthesis structure comprises a thighbone component, a cushion block component, a tibia component and a patella component, the thighbone component is provided with an intercondylar fixing block, the intercondylar fixing block is provided with a protruding part, the inner wall of the thighbone component is provided with a first coating used for bone ingrowth or bone growth, the cushion block component is located between the thighbone component and the tibia component, the outer wall of the lower end of the tibia component is provided with a second coating used for bone growth or bone length, the patella component is located in front of the thighbone component, and the inner wall of the patella component is provided with a third coating used for bone growth or bone length. The knee joint prosthesis structure is a biological type fixed prosthesis structure, various defects and complications caused by bone cement fixation can be avoided, harm to patients and surgical related medical staff due to current bone cement application is reduced, the long-term stability of the prosthesis is improved, the prosthesis loosening rate and the surgical revision rate are reduced, the cost is saved, and the cost is reduced. and the problem of precious medical observation is solved, and great social effect and economic benefit are achieved.

Description

technical field [0001] The invention relates to the technical field of bone joint surgery consumables and instruments, in particular to a knee joint prosthesis structure. Background technique [0002] During total knee replacement surgery, it is necessary to use a knife to remove the diseased bone of the distal femur and proximal tibia, hypertrophic osteophytes, and surrounding soft tissues, and then install the knee prosthesis. Knee joint prosthesis usually includes femoral component, spacer and tibial component. At present, when the domestic knee joint prosthesis structure is installed, it is necessary to use bone cement as the medium between the bone and the prosthesis to tightly connect and fix the two together. Bone cement itself has a fatal bone cement allergic reaction, and medical staff are easy to inhale the smell of bone cement and cause harm to the body. In addition, the use of bone cement increases the use of materials, increases the cost of the operation, and th...
