Abstract

The present invention discloses an extracorporeal shock wave lithotripter and a charging and discharging circuit for an extracorporeal shock wave lithotripter, wherein a shock wave generation apparatus of the extracorporeal shock wave lithotripter comprises a charging circuit (1) and a discharging circuit (2), the charging circuit (1) being formed by a resistor (11, 31) and a capacitor (12, 32), and the discharging circuit (2) being formed by the capacitor (12, 32), a high-voltage switch (13, 33) and a shock wave source apparatus (14, 34). The capacitance of the capacitor is 1.5µF ˆ¼ 2.5µF, the pressure peak value of the focus of shock waves generated by discharging to the shock wave source apparatus (14, 34) by the capacitor (12, 32) is 6Mpa ˆ¼ 20MPa, a positive pressure period of the bottom pulse width is 3µs and a negative pressure period is 5µs. By means of the extracorporeal shock wave lithotripter of the present invention, the bottom pulse width of the generated shock waves is wide, the pressure thereof is relatively smooth, and the pressure peak value of the focus of shock waves is low, and meanwhile, by breaking calculus through stress concentration, side effects on a human body are reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an extracorporeal shock wave lithotripter and a charging and discharging circuit for the extracorporeal shock wave lithotripter. Background technique [0002] With the development of medical technology, more and more extracorporeal shock wave lithotripters are being used. In order to crush the stones in the body more thoroughly, the focus pressure of the shock wave is designed have to Higher and higher. However, what this brings is that the pressure of the shock wave exceeds the tolerance limit of the soft tissue of the human body, causing damage to the soft tissue of the human body. Therefore, how to provide an extracorporeal shock wave lithotripter with little or no damage to the human body is an urgent problem to be solved at present. Contents of the invention [0003] The object of the present invention is to provide an extracorporeal shock wave lithotripter, which can red...
