Embodiment Construction

[0031] The specific technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] An artificial total knee replacement prosthesis capable of reconstructing the anterior cruciate ligament of the present invention includes a liner 1 and a tibial plateau support 2, Figure 1 ~ Figure 4 are the structural schematic diagrams of the liner 1 and the tibial plateau holder 2 respectively.

[0033] Such as figure 1 , figure 2 As shown, the liner 1 is made of a low friction, high density, low wear plastic, such as ultra high molecular weight polyethylene or other resins known to be suitable for these applications. The liner 1 is symmetrical with respect to the center plane vertically and along the front-to-back direction, and its shape is ellipse, rectangle with rounded corners, etc. The liner of the technical solution of the present invention is an ellipse with a rear groove. Liner 1 includes an elliptical plat...

Abstract

The invention relates to an artificial total knee replacing prosthesis which can reconstruct anterior cruciate ligament and comprises a tibia platform supporting part and a liner. The tibia platform supporting part consists of a horizontal platform and a rod part which are fixedly connected; the surface of the liner is provided with a pair of spherical concaves horizontally intervened so as to respectively receive a femur scleromere. The pad and the tibia platform supporting part are provided with a pore canal which respectively penetrates the pad and the horizontal platform of the tibia platform supporting part and are communicated with each other, so as to lead the anterior cruciate ligament to pass through the pore canals, the two ends of the ligament to be fixed on the tibias of a femur ectocondyle, and the horizontal platform of the tibia platform supporting part; thus realizing the reconstruction of the anterior cruciate ligament in a replacing surgery of the artificial total knee.

Description

[0001] Application date: March 2, 2005 [0002] Application number: 200510011371.0 [0003] Invention name: Artificial total knee replacement prosthesis capable of reconstructing the anterior cruciate ligament [0004] This application is a divisional application of the above-mentioned original application. technical field [0005] The invention relates to an artificial total knee replacement prosthesis, in particular to an artificial total knee replacement prosthesis capable of reconstructing the anterior cruciate ligament.
