A method and system for performing abrasion on a surface, such as on the
skin of a patient, is disclosed. The dermabrasion apparatus includes
apparatus for delivering and retrieving material to and from a selected
site to be abraded, a delivery and retrieval hand piece, an abrasive
handling device, and a waste retrieval holding device. The hand piece is
coupled to the abrasive handling device as well as the waste retrieval
holding device, which is further coupled to the delivery and retrieval
apparatus. The abrasive handling device further includes an abrasive
supply device, a receiving channel, a feeding chamber, and a delivery
channel. The abrasive supply device typically is a canister fitted with a
funnel-shaped spout that is inverted into the receiving channel. The
receiving channel feeds abrasive to the feeding chamber. The delivery and
retrieval apparatus, typically a vacuum source that generates a pneumatic
air supply within the abrasion apparatus, causes the abrasive within the
feeding chamber to loft in an arc such that it reaches the delivery
channel. The delivery channel then leads to the hand piece, which is
utilized to apply the abrasive to the surface and then retrieve the waste
debris during the procedure.
