Abstract: PURPOSE: To efficiently and safely crush a targeted calculus with a small power by employing such constitution that a generating mechanism for positive and negative pressure is provided and the calculus can efficiently and selectively be crushed by a tensile force. CONSTITUTION: The calculus 3 at a focal position can be crushed with the impulse wave generated in the neighborhood of a focal point by the nonlinearity of a medium by directly converging an ultrasonic wave surface-generated by a piezo element array 4 connected to a high-voltage pulse generator 2 on the calculus 3 in a body via the water 5 of a model applicator 6. At this time, a positive pulsative voltage 11 is added on the piezo element so as to radiate a compressional wave of positive pressure, thence, a negative pulsative voltage 12 is added on the piezo element so as to radiate the ultrasonic wave of negative phase and negative pressure after the lapse of d/v time 9 in which the diameter (d)7 is divided by internal speed (v). In this way, the tensile force by a force in an opposite direction and to the outside is generated, which enables the calculus to efficiently be crushed.
