摘要
An ultra sonic system is for treatment of urologic diseases. The system includes an ultrasonic generator providing the working field in the frequency range of 15 to 100 kHz and amplitude 2 to 180 mcm, an acoustic unit coupled to the generator and an ultrasonic instrument that connects rigidly with the acoustic unit. The ultrasonic instrument is a multi half-wave concentrator wave-guide, including a core with changeable cross-section and a working end. A length of the working end is to a length of the core as 3/100 to 3/40. The largest size of cross-section of the core in a place of connection with the working end is to the largest size of cross-section of the working end, as 1/20 to 6/1.
