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.

The invention relates to a gas dehumidifying device with a controllable supersonic speed of a shock wave. The air current generates strong rotation when passing a guide vane grid, swells and accelerates to a supersonic speed through a contractile annular channel; the tail end of a central worm is a compression region of the shock wave, and in the compression region, the air current of the supersonic speed decelerates to a subsonic speed through the compression of an oblique shock wave and a normal shock wave; liquid drops continuously grow in the subsonic speed section, move to the outer side of a pipeline under the action of the centrifugal force, and finally enter a liquid-collecting chamber to be discharged by a liquid outlet; while the dry gas enters an exhaust chamber and is discharged by an air outlet. In the invention, the compression region of the shock wave is designed, and the growth region of liquid drops is divided into the supersonic speed region and the subsonic speed region, and the total length of the pipeline is effectively shortened by optimizing the length of the two parts, thereby the loss of frictional resistance caused by the interaction of the air current and the pipeline is reduced; the shape of shock wave in the compression region of the shock wave are designed as the oblique shock wave and the normal shock wave, thereby the strength of a single shock wave is weakened, the loss of the resistance of the shock wave is reduced, and the separation of boundary layers induced by the strong shock wave is avoided.
