This instrument was used to crush and remove the stones in the bladder and urogenital tract which were commonplace in Victorian times.
By turning the end wheel, the jaws of the lithotrite clamp down on the stone and crush it. When the ring on the main handle is be moved backwards this frees the mechanism allowing the central rod to be removed from its cannula for cleaning. The instrument is in good condition with minimal wear to the brass plating and is in perfect working order. Engraved ‘Arnold & Sons London B.M.’
