ABSTRACT:
A calculus disintegrating apparatus includes first and second electrodes which are arranged at the distal end of a probe inserted into a coeliac cavity, and discharge energy sources connected to the first and second electrodes to impresses D.C. impulse voltage across them. The apparatus is arranged to crush a calculus by impact wave resulting from spark discharges produced across the first and second electrodes. A polarity changing circuit is provided between the discharge energy sources and first and second electrodes to vary the polarity of the output D.C. impulse voltage from the discharge energy sources.
