FIELD: medicine.

SUBSTANCE: invention relates to the medical equipment and can be used in urology. The device for crushing of stones in a ureter contains a flexible probe which is executed in the form of the plastic cylinder. In the cylinder the channel is executed. Through the channel there passes an acoustic waveguide. The waveguide bridges the vibrator and a piezoelectric transducer. The waveguide, is executed in the form of the pencil-point concentrator on the cylinder extremity. The piezoelectric transducer is bridged to the generator. The vibrator is established in a cavity of the extremity of the cylinder of a flexible probe. The cavity is executed in the form of an excavation. Depth of excavation is not less than vibrator height.

EFFECT: depression of degree of traumatising of the person at the expense of stone crushing at contact of the pencil-point concentrator to a stone located in an ureter, and influences through the pencil-point concentrator ultrasonic fluctuations.
