An improved ultrasonic lithotriptor probe for performing fragmentation and removal of calculi deposits in the kidney and upper ureter wherein high frequency sound waves are utilized to disintegrate the calculi or stones based on placing the probe against the stones and causing them to disintegrate due to the ultrasonic energy. The probe is coupled to a transducer which drives it and the probe is hollow and aspiration is utilized to remove the particles of the stone through the probe. The probe extends into the transducer which prevents the probe from clogging. Also, the end of the probe which engages the stone is provided with a slit so as to prevent it from being clogged by the stone so as to cause the aspiration to be interrupted when the end of the probe extends into the confines of the stone in that the split will allow liquid to pass through the probe and continue to cool it and to remove fragments through the probe.
