DEVICE FOR GENERATING OF ONE-IMPULSE SHOCK WAVE Russian patent published in 2009 - IPC A61B17/22 A61B17/16 

FIELD: medicine.

SUBSTANCE: invention concerns medical equipment and can be used in urological surgery for crushing of stones in renal ducts. The device of generating of an one-impulse mechanical shock wave contains a shock agent for high rate striking blows on an agent of generating of a shock wave. The wave is transferred by shock wave transmission media to the object intended for crushing with which the mentioned agents are in immediate or indirect contact. The shock agent is set in motion under the influence of force of expansion of the compressed gas. Gas is submitted before producing every impulse of a shock wave to an agent of accumulation, which is supplied with gas of high pressure from independent agents of storage by means of extenders of gas and food and hermetic sealing agents. Gas is released by manual actuating of control facilities.

EFFECT: device generating a shock wave of the big amplitude transferred through a skin or through natural ways by means of an endoscope is as a result framed, allowing to carry out controlled crushing of an urinary stone for its fragmentation on a small number of pieces in the size necessary and sufficient for their extraction manually by means of forcepses through endoscope, entered for a fragmentation of stones, for a direct vision behind them, their capture and extraction.
