1. A power operated surgical tool comprising:
an external housing adapted to enclose and support various internal components;
a transmission;
a motor secured within the external housing, the motor including an output shaft, the motor output shaft connected to the transmission, the transmission including an oscillating rotation drive mechanism for causing a cutting tool to rotationally oscillate about a longitudinal axis of the cutting tool, the oscillating rotation drive mechanism having a link that revolves about the motor output shaft at a swing angle and is attached to a rotatably mounted shuttle so that the distal end of the link rotates around the motor shaft while a pivot axis at the front portion of the link is positioned to rotate upon a neutral point, causing the shuttle to rotationally oscillate about an axis lateral to the motor output shaft.
