Apparatus for destroying calculuses.

摘要

An apparatus for destroying calculuses detects an expiration end period of a human body (1) by a detector (9). A pulse generator (14) generates a first drive pulse to drive destroying energy radiation in synchronism with a start point of the detected expiration end period. Succeeding to the first pulse, another pulse generator (13) generates a train of pulses at a rate as set by a pulse rate setting circuit (11). By the pulse train, the energy is repeatedly radiated to the calculus during the detected expiration end period.
