Abstract
Rotary motion is converted into linear motion for a surgical instrument, such as a saw, by mechanically connecting the eccentric shaft portion of an off set shaft driven by the rotary motor to a drum having a collet interconnected by a yoke. The eccentric shaft portion of the off set shaft includes a bearing and spherical ring disposed between the eccentric shaft portion and the bifurcated arms of the yoke and through a radially extending projection fitted into a hole in the drum drives the drum in a rectilinear motion. The offset shaft portion, the eccentric shaft portion and drum are parallelly disposed relative to each other and enhances the life and provides a substantially quieter and vibration free surgical instrument
