Abstract

The present invention employs a saw blade (10) made of highly polished metal having a highly smooth surface finish with no sharp edges along the length and a cutting guide (11) having a smooth surface made of multiple use disposable plastic used in combination. The mirror polished upper and lower surfaces (22) of the blade minimize the friction generated at interface of the saw blade and the walls of the cutting guide slot (13). The saw blade is connected to a motor driven power tool (24) to derive the power while cutting the bone. Therefore, the blade on being actuated moves within the plastic guide slot in a back-forth or sideways oscillating motion resulting in lesser frictional wear of the blade-guide assembly as a whole. Lesser friction prolongs the life of the blade while not affecting the accuracy of the cut surface generated, thus being a cost effective solution to the state of the art technology.
