Abstract
A combination medical device for removing and treating tissue in a patient is disclosed. The device includes a reusable handle and a blade selectively connectable to the handle. The blade includes an outer sleeve having a lumen with an inner shaft disposed therein. The inner shaft may be coupled to a motor drive unit disposed within the handle and may rotate so as to mechanically cut tissue as the inner shaft rotates. The outer sleeve includes at least one electrode for electrosurgically treating tissue. The reusable handle includes at least one control switch for controlling a parameter associated with the rotation of the inner shaft. The blade also may include a switch assembly in electrical communication with the at least one electrode, the switch assembly including attachment means for selective attachment of the switch assembly to the reusable handle.
