This article introduces the placing signage of the extracorporeal cardiac shock wave source transducer and the trigger system of high voltage. The shock wave source transducer composed by cylinder coil, metal iflm and relfection cup which can generate and focus the shock waves. High voltage trigger system includes: high voltage booster module, voltage control module, energy storage capacitor array, high voltage switch module, charging counting module and mixed signal processing module. The shock wave trigger system can output high voltage pulse whose frequency and amplitude is stable. When the shock wave source sensor receive the high voltage pulse, it can complete the conversion from electric energy to mechanical energy, and emission low energy, narrow pulse width and high pressure shock wave.
