体外震波碎石的碎石率与椭圆形反射体的内孔镜面光洁度有极密切的关系。在临床使用中,我们发现新的反射体对结石的粉碎效果很好,一旦经过几十例患者碎石后,反射体均有不同程度地被电火花烧灼及受水垢等的侵蚀,造成镜面被蒙上一层薄雾状,影响碎石治疗效果。清洁反射体往往是被人们忽视。但用一般的擦拭方法难以清除,解决 Extracorporeal shock wave lithotripsy lithotripsy and elliptical reflector bore mirror finish has a very close relationship. In clinical use, we found that the new reflector on the crushing effect of stones is very good, once after dozens of patients with gravel, the reflectors are varying degrees of EDM burning and scaling erosion, resulting in the mirror was Put a layer of mist, the impact of gravel treatment. Cleaning the reflector is often overlooked. But with the general method of wiping difficult to remove, solve
