技术原理当一个高压电荷(8～24 KV)通过一个水下放电器电极时,就产生冲击波。碎石机最初产生的冲击波被聚焦于半椭圆形反射器的焦点,使其重新聚焦在椭圆的第二个焦点上。聚焦可使90%的能量到达第二个焦点,局限于一个2厘米的范围。冲击波通过一盆脱气和去离子的水后能量无变化,再通过机体组织时,其能量就传导到不同声阻的物体上,如结石和空气等。操作时,将病人放在一组座椅里并悬浮在冲击波发生器上的水槽里,
Technical Principle When a high-voltage charge (8 to 24 KV) passes through a submerged-discharge electrode, a shock wave is generated. The shock wave originally generated by the lithotripter is focused at the focal point of the semi-elliptical reflector, refocusing it at the second focus of the ellipse. Focusing allows 90% of the energy to reach the second focus, limited to a 2 cm range. Shock wave through a basin of degaussing and deionized water after no change in energy, and then through the body tissue, its energy is transmitted to different acoustic resistance objects, such as stones and air. During operation, the patient is placed in a set of seats and suspended in a sink on the shock wave generator,
