本文扼要介绍了E8410冲击波肾碎石机工作原理和主要特性。动物实验采用人肾石标本植入法制备18只狗肾石模型,冲击治疗均获成功,动物健康存活。系统医学安全试验证明冲击治疗安全可靠。临床前实验报告了心电防护、提高冲击命中率的措施和正常人受试情况。 This article briefly describes the E8410 shock wave lithotripsy machine working principle and the main features. In animal experiments, 18 models of kidney stones were prepared by implantation of human kidney stone specimens, all of which were successfully treated by impact therapy and the animals survived healthily. System medical safety test proved that impact treatment is safe and reliable. Preclinical experiments reported ECG protection measures to improve the impact hit rate and normal subjects.
