Paper Abstract

This article presents the further developments of combined laser-ultrasound medical technologies with paying attention the possibility ultrasound in surgery and therapy. The analyses of main effects at the low frequency ultrasonic treatment of biotissues including cavitation, acoustic streams, acoustic pressure, mechanical influence etc are analyzed. The main promising areas of application of low frequency ultrasound are considered including bactericidal treatment of infections wounds, spray treatment of wounds in head and neck surgery, tumor treatment etc. In particular the clinical result of using ultrasonic devices based on imposing ultrasonic oscillations in a range of 22-66 kHz on a cutting instrument with a special form, radiation intensity up to 10 W/cm2 and oscillation amplitude up to 40-60 micrometers with respect to oncology for halt bleeding from a tumor, liquidating pain, acoustic denervation are presented. Some limitation of medical application of ultrasound are discussed and perspective combination with laser for increasing efficiency of new combined technologies are found. Among them: combination photodynamic therapy and ultrasonic treatment of tumors, laser-ultrasonic treatment of infections wounds including using spray, laser-ultrasonic drug delivery. The preliminary result of experimental study of some of above-mentioned technologies are presented.
