ULTRASONIC BONE THERAPY APPARATUS AND METHOD

摘要

This invention is a method of ultrasonic bone therapy that subjects a bone (10) to an ultrasonic excitation pulse signal of finite duration, supplied to a transducer (14) next to the bone, and involving a sinusoidal signal in the ultrasonic region to approximately 2 Mhz peculiarly modulated by a sinusoidal signal with frequency between 0 Hz and about 25 kHz; the excitation signal is repeated in the range of 1 Hz to 5000 Hz. The exposure time for therapy is chosen to be in the range of 5 minutes to 1 hour, for 1 time to 3 times a day, for a period of days as necessary for healing or for promoting bone growth and ingrowth. An apparatus for implementing the above method for ultrasonic bone therapy is disclosed comprising a transducer (14) having a transmitting and a receiving element, a special waveform signal generator (20), and a computer (16) for performing the necessary operations defining a preferred treatment regime.
