Apparatus for ultrasonic therapeutic treatment
First Claim
1. A non-invasive dual-frequency body-applicator therapeutic device, comprising first and second ultrasonic piezoelectric transducers on a single axis of longitudinal acoustic propagation, the first transducer including at one longitudinal end a generally cylindrically annular body-application head having a cylindrical bore on said axis, said first transducer having means for independent connection to a first source of ultrasonic acoustic-signal excitation at a first frequency within the range 10 kHz and 4 MHz;
- said second transducer having means for independent connection to a second source of ultrasonic acoustic-signal excitation at a second frequency within said range and being mounted in said bore with at least some acoustic isolation from said first transducer, and having at said longitudinal end a body-application head;
said first frequency being lower than said second frequency, and said annular body-application head having a body surface-active engagement face of a material having impedance-matching properties with respect to engaged regions of a body-tissue area contacted by the impedance-matching active-engagement face of said annular body-application head.

Abstract
The method and apparatus of the invention are directed to surgically non-invasively treating skeleto/muscular injuries or of diagnosing bone fractures, involving application of two components of ultrasonic energy, to an external surface of living tissue, wherein the two components are of different frequencies in the range between 10 kHz and 4 MHz, and wherein separate transducers, each uniquely supplied with an excitation signal at a different one of the same two frequencies, are directionally disposed for acoustic propagation on the same directional axis.
