ABSTRACT:
An elongated dissecting tool adapted to be driven by a rotary motor is confined within an elongated tool guide which is attached to the rotary motor. A tool is coupled to the motor by means of a suitable chuck; and the tool guide includes bearings for rotationally supporting the elongated dissecting tool. The dissecting tool includes a specially engineered cutting tip at its distal end having at least one longitudinal cutting edge; and this tip is partially enclosed within a shroud formed at the distal end of the guide. The shroud provides an opening for access of the cutting tip to the tissue to be dissected protects adjacent anatomical structures from inadvertent injury, and provides a cutting edge coacting with the cutting edge of the cutting tip for the dissection of soft tissue.
