Abstract

A lithotomic apparatus includes a probe for insertion into the body cavity. A distal tip is fixed to the distal end of the probe and has nozzles. Each nozzle has a rear end communicating with a feed passage defined in the probe and a front end opening to the distal end face of the distal tip. A high-pressure fluid supplied from a source is fed to the feed passage of the probe and pulsatively ejected from the nozzles toward a calculus in the body cavity by a drive mechanism.
