ABSTRACT:
A shock wave lithotrite has a soft iron mass body (33), which is accelerated by the magnetic field produced by a coil (19) and, on impact against a shock receiver (26), abruptly transmits as a shock impulse the kinetic energy thereby accumulated. The shock impulse is transmitted by the shock receiver (26) to an impulse conducting wire (13), passes through the latter in the form of a shock wave propagated between the molecules and passes out at the other end of the wire. The coil (19) can be connected to one of the usual high-voltage pulse generators (11) used for electrohydraulic lithotrites.
