Abstract
A bone, cartilage, and disk removal tool assembly is provided with a motor mounted in a housing. A spindle is mounted for rotation to the housing. A rack-and-pinion mechanism is operably driven by the motor and connected to the spindle to oscillate the spindle for providing a rotary oscillating cutting operation. According to at least another embodiment, a plurality of cams is supported in the housing and driven for rotation by the motor. A plurality of followers is mounted for rotation to the housing, in engagement with the plurality of cams so that one rotation of the plurality of cams oscillates the plurality of followers more than once while preventing over-rotation of the plurality of followers. A peak angular acceleration of the spindle is less than nine million radians per second squared.
