Description

一种多动力体内碎石机
技术领域
本发明涉及用于人体内结石的碎石机，具体是集超声、气压弹道、激光于一体的一种多动力体内碎石机。
背景技术
超声波体内碎石是一种较好的微创治疗结石的技术，一般是采用顶端装有超声换能器的探针通过内窥镜接触结石来进行碎石。具体地，这种碎石技术利用超声发生器产生的电振荡使超声换能器产生高频机械振动，并通过超声电极传递到变幅杆上，使其顶端发生纵向振动，当超声探针与坚硬的结石接触时产生碎石效应。变幅杆为中空探针，灌洗液和结石屑可通过中空的变幅杆由真空负压吸引设备吸出体外，从而实现碎石清石的治疗目的。这种方法的好处是去石彻底，治疗后很快就可以康复，并且不容易复发。但是，现有的超声碎石仪只对约15％的易碎的小结石有效。
另外，还有一种气压弹道碎石技术，其由气压弹道施加碎石能量，将结石击碎。这种气压弹道碎石仪虽然碎石能力较强，但是由于治疗时只能碎石，不能当场清石，可能会留下结石复发和碎石堵塞尿路的隐患。
再者，还有一种激光碎石技术，其基本特点是将激光发射源送入体内结石位置，通过强大的激光能量将结石粉碎。目前使用的碎石激光有调Q.Nd:YAG 激光（波长1064nm），双波长激光（绿光波长532nm，红外光波长1064nm），红宝石激光器（波长694nm），金绿宝石激光，钬激光（波长2100nm）等。激光碎石技术比较适合结石较大的情况，碎石效率较高，但其也存在只能碎石、不能清石的缺陷。
