Abstract: A method is described for brightening tattoos or pigmented images formed below the epidermis of an individual. A skin treating device having a treatment tip with a crystalline abrasive material permanently bonded thereto is moved across the skin surface covering the tattoo. The procedure results in the bonded crystalline abrasive material removing a portion of the surface of the epidermis of the skin area over said tattoos or pigmented images, resulting in a brightening of colored or black line tattoos and a sharpening of the lines in the image. Simultaneously applying a vacuum to the skin surface during the procedure and the application of skin serum during or after the procedure enhances the results.

Abstract: A liquid delivery wand includes a centrally located fluid storage chamber. An absorbent pad is located within the working end of the wand for applying the treatment liquid to the skin while a vacuum is applied to the skin through an abrasive coated treatment tip. Coaxial, cylindrical tubes with flow channels between tube surfaces control the flow rate, the pressure drop being established by the close fit and length of adjacent surfaces of the coaxial components. The flow rate of the liquid is adjustable by simply rotating the interfitting components. The chamber that holds the liquid is sealed from the atmosphere at the distal and proximal end. When the wand is connected to vacuum and the distal end contacts the skin, the vacuum applies a negative pressure to the fluids within a fluid chamber. A small portion of liquid is thus transferred to wet the filter pad.

Abstract: A treatment tool and tissue collection system, for removal of outer layers of skin to provide a revitalized, fresh skin surface, and a method of using same, comprising a abrasive tipped tool mounted on the end or within the end of a hollow tube, said tube being connected to a source of vacuum. The vacuum aids in maintaining intimate contact between the abrasive tip and the skin during the treatment process and transports the removed tissue to a collection container. The abrasive surface within the tube is a motor driven abrasive pad. Contact between the pad and the abrasive disk is brought about or increased by application of a vacuum through the tube to the skin surface.

Abstract: A surgical drill uses burs with circular grooves about the circumference that are polygon shaped in cross section but curved along the length of the bur so as to accept locking balls therein. The burs slide within a tubular drive shaft that has transverse holes therein to guide the locking balls. A cylindrical cam surrounds the drive shaft and the locking balls to urge the balls radially inward into the bur groove. The cam is spring loaded axially. A spring loaded central pin within the drive shaft slides between the balls and urges the balls radially outward when no bur is inserted. A thumb button is used to disengage the ball surrounding cam.
