Abstract:
A device for creating a plurality of small wounds in a patient's skin and introducing topically-applied substances therein is disclosed. The device comprises a rigid plate that has a top side, a bottom side, and at least one peripheral edge that connects the top and bottom sides. The device further includes a tool attachment means fixed with the top side of the plate and adapted to fix the device to a motorized tool that oscillates reciprocally back and forth along the longitudinal axis of the plate. A plurality of needles project generally orthogonally away from the bottom side of the plate. In use, the plate is fixed with the tool and the tool activated. The bottom side of the plate is then applied to the skin of the patient such that each needle repeatedly pierces same to create the plurality of small wounds therein. When the substance is applied to the skin first, each needle draws a portion of the substance into the skin with each oscillation of the tool.
