FRACTIONAL HANDPIECE FOR DERMATOLOGICAL TREATMENTS

摘要

A medical device includes a housing that is moved along a surface of a target tissue in a longitudinal direction. One or more supply lines conduct air and water to the housing. A pulse emitter emits electromagnetic pulses toward the surface at a repetition rate for the pulses to produce ablation holes in the tissue. The pulse emitter includes optical components and is configured to direct the air against the optical components to keep the optical components clean. One or more nozzles emit the water and the air in an air/water spray to moisturize and cool the target tissue prior to laser application.
