Bone shaping device for knee replacement

摘要

A bone surgery device with a reciprocating cutting head. The device comprises several sets of shaping surfaces sometimes including cutting blades, which are located and oriented so as to shape the distal end of the femur and the proximal end of the tibia for total knee replacements and unicompartmental knee replacements. The device, which may be hand directed or aided by spatial and directional guiding mechanisms or an optical navigation system, may also include both coolant supply for controlling heat during bone cutting and shaping, and a suction method for carrying away fluid and debris. The device is substantially configured to the artificial joint component to be attached thereto.
