Abstract
A lithotripter is provided with the usual open ended reflector covered by a diaphragm and filled with a conductive liquid such as salinated water. A spark gap is provided at the focus point of the reflector, and a spark generator is connected thereto for providing a succession of sparks across the spark gap, wherein the light guide has an entering end positioned within the reflector and adjacent the spark gap to convey a representation of the spark outside of said reflector. The light guide has an exit end to which a light sensitive device is connected for converting the light signal to an electric signal. The electric signal is connected to means for providing a visual display of the electric signal.
