ABSTRACT:
A multipurpose handpiece for use with an abrasive material delivery system is disclosed wherein the handpiece includes channels for delivery and removal of an abrasive material applied to a patient's skin. The invention includes a multi-port applicator for selectively applying the abrasive material, said application of abrasive material suited for different areas of tissue such as stomach versus eye lids. The present invention comprises a pair of tubings connected to a housing for delivery and vacuum removal of abrasive material, and a flow regulator disposed within the housing. Connected to the housing at an application end is a resurfacing applicator with a plurality of differing sized openings designed for different types of tissue. The present invention includes means for blocking the unused openings while permitting injection of the abrasive material through a selected opening. The blocking of the unused openings may be achieved by a shield or covers for each opening. The present invention is further adapted to stop the flow of the abrasive material while the openings are being changed, and means are provided for rotating the resurfacing applicator, and for aligning the resurfacing applicator opening with the injection port of the flow regulator for even and uninterrupted flow of material.
