Abstract
The method and device of the present invention for wound treatment with a combination of laser and ultrasound waves comprises a probe to produce a laser beam and transducer to produce ultrasonic waves. The ultrasonic transducer has tip with a distal end comprising a radiation surface. A liquid is directed to the radiation surface wherein an directed atomized particle spray of the liquid is created upon contact of the liquid with the radiation surface. The laser beam and spray directed to the wound from at least 0,1 inches transmits ultrasound waves as well as particles and has an radiation, irrigation, mechanical cleansing, liquid energizing and bactericide effect on the wound.
