Lithotripters, Intracorporeal, Impact, Ultrasonic
Definition : Intracorporeal lithotripters that use a probe consisting of an ultrasound transducer and a hollow steel probe. An external generator powers piezoceramic elements and produces high-frequency (20 to 27 kHz) sound waves. The transducer converts the sound waves to vibrations that propagate along the hollow probe to a movable impact tip. The probe is placed in contact with stones and the probe vibrations cause the stones to fragment. In some units, the probe is connected to a suction pump, which aspirates stone fragments through the probe lumen.
