Abstract
A dermabrasion instrument includes an outer member and an inner member rotatably disposed in the outer member with an abrading member of the inner member exposed from the outer member. An aspirating passage in the abrading member establishes communication with an aspirating channel of the inner member from externally of the abrading member so that debris from abrasion of the skin by the abrading member is evacuated through the inner member. The outer member may include a shield disposed over the abrading member to contain the debris. The instrument may include an irrigating port for discharging irrigating fluid adjacent the abrading member. A dermabrasion instrument assembly includes an abrading instrument releasably coupled to a powered surgical handpiece. The instrument has an aspirating channel and the handpiece has a suction port connectible with a source of suction to effect evacuation of debris through the abrading instrument and the handpiece. A method of dermabrasion includes the steps of rotating an inner member of an abrading instrument within an outer member of the instrument to rotate an abrading member of the inner member, abrading the skin with the rotating abrading member and aspirating debris from abrasion through the inner member.
