摘　　要：目的探讨改良点触式探针提高超声碎石效率的可行性。方法在原超声探针的前端打磨3个缺口,形成3个点状凸起,做成点触式超声探针。将一水草酸钙碳酸磷灰石混合型肾铸型结石、一水草酸钙肾铸型和一水草酸钙肾潴留型光滑结石分别用点触式探针与平面探针行体外碎石。分别记录碎石时间、清石量和碎石速度。结果两种探针体外碎石速度有统计学差异(P<0.05),平面探针难以击碎的结石点触式探针仍可击碎,且一水草酸钙光滑的肾潴留性小结石差异更明显(P<0.01),点触式探针的碎石速度是平面探针的7.59倍。结论体外实验表明,改良探针碎石速度快,效率高,可显著提高超声清石碎石速度。Objective To investigate the feasibility of improving the modified probe ultrasonic lithotripsy. efficiency.Method In front of the ultrasonic probe 3 gaps were ground to form 3 raised points to make a contact type ultrasonic probe.The calcium oxalate monohydrate carbonate apatite mixed type renal staghorn calculi,calcium oxalate and calcium oxalate monohydrate renal staghorn renal calculi were retention type smooth with point contact probe and the plane probe for eswl. The gravel time,stone clearance volume and velocity were recorded respectively. Results The two probes in vitro rubble speed had significant difference（ P 〈0. 05）,the contact type probe can crush stones that is difficult to be broken by the plane probe point. And the renal retention of small stones of smooth calcium oxalate monohydrate had more obvious differences（ P〈 0. 01）,a contact type probe gravel is 7. 59 times as fast as the plane probe. Conclusion In vitro experiments showed that the improved probe gravel,fast speed,high efficiency,can significantly improve the speed of ultrasonic cleaning stones.
