ABSTRACT:
An extracorporeal lithotripter is provided with an ultrasound transducer on the rotational center line of the reflector and substantially at the open end of the reflector. The transducer is protected against shockwaves by a metallic housing in which it is mounted. The transducer at one end engages the housing through a resilient plastic disk, and is spaced laterally from the housing by a rubber O-ring adjacent the open end of the housing. The housing directly shields or shadows the transducer so that shockwaves are not transmitted to the transducer, which could damage the transducer and shorten its life.
