Method for therapeutic action with a ultrasonic field to biological tissues and a device for this purpose

Abstract

The invention relates to the art of medicine and medicine equipment and concerns techniques and means for therapeutic action to biological tissues with electromagnetic fields. The invention allows to improve the therapeutic effectiveness of action with ultrasonic fields to biological tissue. The action is effected with the ultrasonic fields having frequencies corresponding to intrinsic frequencies of mechanical oscillations a cell membrane (that is, to resonance frequencies). The action to the cell membranes is effected in a hydrodynamic non-destructive mode. A device for therapeutic action with a ultrasonic field to biological tissues comprises a ultrasonic oscillation generator, an acoustic assembly and a ultrasonic tool that is a replaceable operating member having an operating end, and further has a liquid phase supply system. The generator is capable of forming the ultrasonic field having a frequency of from 20 to 30 kHz. A form of the operating end of the ultrasonic tool corresponds to a form of a receiving surface of a biological tissue, and is described by cubic splines.
