[0022] The technical scheme of the present invention is further explained in conjunction with the drawings:
[0023] see figure 1 , The present invention is a two-rotation two-shift motion synthetic knee replacement prosthesis tibiofemoral joint wear test machine, which is composed of two parts, the right part and the left part. The positional connection relationship between them is: the left part is on the left of the testing machine. Side, the right part is on the right side of the test machine, the rocker in the crank-rocker mechanism in the right part is connected with the main shaft in the femoral system in the left part.
[0024] The left component produces flexion and extension wear motion between the prosthesis joint surface, and the right component is the driving structure in the flexion and extension motion of the prosthesis joint.
[0025] The technical scheme and principle of the left part:
[0026] The left part mainly includes the main shaft 25, the femoral prosthesis we...
