Abstract: The invention relates to a single-blow mechanical shockwave generation device used in urological surgery for disintegration of urinary duct stones, comprising a striking device which strikes a shock wave generation device at high speed. The shock waves are transmitted by a shock wave transfer device to an object for destruction with which the shock wave transfer device is in direct or indirect contact. The striking device is displaced by way of the expansion of a high-pressure gas introduced prior to each shock wave generation into an accumulation device. The accumulation device is supplied with high pressure gas from independent gas stores and with supply and sealing devices. The stored gas is released by the manual manipulation of a control device which connects the accumulation device to the striking device.
