A lithotripter having a shockwave generator having a cavity filled with water, further having an ultrasonic, locating transducer mounted by means of a holding device which includes metallic inner and outer shells each having a large acoustic impedance as compared with water and an acoustically attenuating layer interposed between the two shells; the shells are spaced from each other so that the shockwaves will be eliminated by interference.

Ultrasonic transducer in lithotripters

A lithotripter in general includes a patient's rest, a therapeutic head for the production of shockwaves, an ultrasonic transducer, and a locating arm for moveably mounting the transducer on the therapeutic head; and an additional holding arm has one end connected to the patient's rest and the other end is releasably connectible to the transducer for providing for a dual holding of the transducer once a concrement has been located. The holder includes a structure for motion retardation, i.e. braking action on of the one end relative to the other end.
