Embodiment Construction

[0028] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0029] In the prior art, according to the degree of damage to the patient's knee joint, various additional structural forms of the femoral condyle prosthesis are used in the design to adapt to different cases, such as the condyle femoral prosthesis with the posterior cruciate ligament preserved , Posterior stabilized condylar femoral prosthesis without retaining the posterior cruciate ligament and semi-restricted femoral condylar prosthesis, etc. Among them, the inner and outer condyles of the condylar femoral prosthesis with the posterior cruciate ligament retained are connected as a whole by the patellar slide, and the rear of the bicondyle is kept open to accommodate the cruciate ligament; t...

Abstract

The invention provides a femur condyles prosthesis component. The femur condyles prosthesis component comprises a prosthesis base body part and a limiting part arranged on the prosthesis base body part. The prosthesis base body part is provided with a receding notch part (20) used for being matched with a central stand column of a tibial plateau prosthesis. The limiting part comprises a transverse limiting part (51) arranged at the opening end of the receding notch part (20). The prosthesis base body part comprises a bone combining layer (10), a ceramic layer (30) arranged above the bone combining layer (10), and a buffering layer (40) arranged between the bone combining layer (10) and the ceramic layer (30). According to the technical scheme, the problems that in the prior art, a femur condyles prosthesis component cannot be compatible with the implanting stability and the indication application range can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a femoral condyle prosthesis component. Background technique [0002] At present, artificial knee prosthesis is mainly divided into femoral condyle prosthesis and tibial plateau prosthesis. Among them, the tibial plateau prosthesis is usually composed of a metal tibial tray and an ultra-high molecular weight polyethylene spacer arranged on its upper part, and the material of the femoral condyle prosthesis is usually metal, and the superheight of the femoral condyle prosthesis and the tibial plateau prosthesis Compatible with molecular weight polyethylene spacers. [0003] In the prior art, the basic form of the femoral condyle prosthesis has the articular surface of the medial and medial condyles and the articular surface of the patellar slideway. According to the degree of damage to the patient's knee joint, the femoral condyle prosthesis is designed with various a...
