Abstract

A cutting center for shaping the femur condyle is composed of a speed variator, a main drive shaft in said speed variator, a main drive gear installed to said main drive shaft, at least one driven gear matched with said main drive gear and installed to the first driven shaft in said speed variator, and a cutter installed to the extended end of the first driven shaft.

Description

technical field [0001] The invention relates to a femoral condyle forming cutting center, in particular to a cutter for one-time forming processing of the femoral condyle. During use, the cutter for shaping and processing the femoral condyle provided by the present invention is installed on the knee joint by means of a fixing device, and multiple surfaces required for shaping are processed on the human femoral condyle at one time by sawing, milling, filing, and grinding. Background technique [0002] In some special cases, it is necessary to install a prosthesis at the knee joint of the human body. At this time, the femoral condyle must be reshaped and cut, so that the end of the femoral condyle has a specific shape, so that it can be fitted with the prosthesis that is suitable for it. [0003] Currently, during a total knee arthroplasty procedure to reduce an injured knee, orthopedic surgeons often spend a long time ensuring that the articulation of the knee is balanced. A...
