Design and experimental force analysis of a novel elliptical vibration assisted orthopedic oscillating saw

Orthopedic procedures such as osteotomies, and hip and knee joint replacements involve plane processing owing to the demand of implant assembly and fixation, for example, the surface to fixture interaction of the femoral component during total knee replacement. Orthopedic powered saws have been designed and widely used for plane processing since 1890s [1]. There are three main requirements for bone sawing: high efficiency, low temperature, and low cutting force. Considering the operation time of such a surgery, the high cutting efficiency is the most crucial factor for bone resection devices.
