SELF-CONTAINED HANDPIECE AND METHOD FOR OPTICAL TISSUE SURFACE TREATMENT

摘要

A handpiece for treatment of the surface of a target tissue with at least one light beam is provided, the handpiece including a housing, at least one light source for generating at least one light beam, an opening for allowing the emission of the at least one light beam out of the housing and towards the target surface, a mechanism for controlled displacement of the at least one light source to move the at least one light beam across the target surface; and a controller for controlling the mechanism. A method is provided for treating a tissue surface with a light beam that includes directing a light beam towards the tissue surface, focusing the light beam at the tissue surface so that the focal point is positioned proximate the surface of the tissue so that the diameter of the light beam is smaller at the surface of the tissue than below the surface. The light beam is moved to create a pattern on the tissue, and it is moved in response to manual movement of the handpiece to overcome unwanted movements and provide a desired spot pattern on the tissue surface.
