自八十年代初,西德 Chaussy 等首次报道72例“水中聚焦冲击波体外粉碎肾结石”的临床效果以来,体外震波碎石术(简称 ESWL)引起了各国学者的广泛重视并得到迅速发展,治疗效果越来越好。现综合国内外近年来的有关文献作一简述。(一)碎石机工作原理1.发生器:目前世界上运用的碎石机发生器工作原理主要有两种:①置于椭圆反射器第一焦点处的水中电火花使局部水汽化而产生的冲击波经椭圆反射器聚能于第二焦点,以粉碎该焦点处的结
Since the early eighties, West Germany Chaussy first reported 72 cases of “underwater focused shock wave in vitro crushed kidney stones,” the clinical effect of extracorporeal shock wave lithotripsy (ESWL) has attracted widespread attention of scholars from all countries and the rapid development of treatment The effect is getting better. Now a comprehensive summary of the relevant literature at home and abroad in recent years. (A) crushing machine working principle 1. Generator: The current world of crusher generator working principle there are two main ways: ① placed in the first focus of the elliptical reflector in the water spark to produce local water vaporization Of the shock wave through the elliptical reflector converged to the second focus, to smash the focus at the junction
