More specifically, the invention relates to such an instrument wherein the means for detecting comprises means for sensing the conductivity of the liquid medium. Instruments of the above-described type, for example, instruments for disintegrating stones in a human patient, are known in the art as illustrated in, for example, U.S. Patent 3,902,499, Shene, issued September 2, 1975. The known instruments suffer the disadvantage of not having any indication when the lithotrite may be touching the tissue of a patient. As will be apparent, if the lithotrite is in such a position when discharged, then the patient can be hurt. It is therefore an object of the invention to pro...
