Abstract
An extracorporeal lithotripter has a base mounted on wheels for movement about a floor or the like. There is an upright extensible support on the base caring a horizontal extensible support. The horizontal support has a swivel at its outer end with a pair of diverging arms pivotably carrying a truncated ellipsoidal reflector having an otherwise open end closed by a flexible membrane. A spark gap is disposed at the first focal point of the reflector. The second focal point is beyond the membrane and is to be placed on a kidney stone or the like to be disintegrated. Parts are manually movable, and an electric screw jack controls extension of the upright support. The movable parts are all locked by electric brakes except when a pushbutton switch is pushed and held to unlock the brakes for movement of the movable parts. The lithotripter is remarkably simple, rugged and inexpensive.
