[Optimizing instrument geometry of oscillating saws for use in medicine].

The sawing of bones is an often employed method in separating bones for osteotomies. In the application of reciprocating saw blades appear various risks for like thermal and mechanical damage of the bone delaying the healing process. In order to avoid such risks the geometry of sawing tools has to be optimized. Important demands are an easy handling of the reciprocating saw blades, shortening of the cutting time, reduction of temperature and an accurate to measurement and form guideway of the sawing tool. In this paper a newly optimized geometry of tool is established fulfilling the above-mentioned demands and avoiding bone damage by application of tools.
