Mechanical shock wave producing device for disintegrating urinary calculus, has strike unit moved by expanding gas under high pressure introduced in accumulation unit before production of each shock wave

摘要

The device has a strike unit (2) to strike a shock wave generator unit (3) for creating waves to transmit to an object to be disintegrated by a shock wave transmitting unit (4). The strike unit is moved by expanding gas under high pressure introduced in an accumulation unit (5) by a gas expansion unit (7), before producing each shock wave. The gas under high pressure is supplied to the unit (5) from a storage unit (6). The stored gas is freed by manual operation of a control unit (8) that is in contact with the accumulation unit (5) and the strike unit (2).
