超声碎石方法及超声碎石钳
 
技术领域
本发明涉及一种超声碎石方法及超声碎石钳。
 
背景技术
在经济高速发展的今天，人的生活节奏加快、饮食结构发生变化，很多人坐办公室工作的时间都很长，缺乏运动，有的人因为工作紧张，常常一天喝不上几次水，有的索性不喝。结石病发病率越来越呈上升趋势。所以应用于碎石的医疗设备需求日益旺盛。其中尤以体内超声碎石已其对人体伤害较小而成为碎石的首选。然而在碎石的过程中会经常出现结石在体内滑动难以定位的现象，结石的滑移不仅会容易造成超声器对其它健康组织的损伤，酿成医疗事故，而且大大延长了碎石时间，本专利申请就是基于这个难题而做出的解决方案。
 
发明内容
本发明的其中一个目的在于提供一种超声碎石方法，该超声碎石方法有利于实现对患者体内易于滑动的结石进行定位碎石。
本发明超声碎石方法，其特征在于：利用在体内超声碎石器前部设有一可牢固夹持人体内结石的夹具，以利于超声碎石器准确定位后超声碎石。
上述夹具为可伸张和收合的夹具。
上述夹具为爪形夹具。
上述夹具为负压吸结石夹具。
本发明的另一个目的在于提供一种超声碎石钳，该超声碎石钳有利于实现对患者体内易于滑动的结石进行定位碎石。
本发明超声碎石钳，其特征在于：包括碎石钳主体，所述主体包括用于夹持结石的结石钳体、用于支撑结石钳体以使钳口张、合的支撑柄体，以及发生超声波的能量器。
上述结石钳体为一根细杆，所述细杆端头部自然状态下呈两张开的瓣体。
上述支撑柄体包括设置在其前端部的结石钳体撑管，和以让结石钳体在支撑柄体体内伸缩的推拉柄，所述推拉柄包括呈U型的弹性体，所述弹性体的U形一端部铰接连接在支撑柄体上，另一端部与套置在结石钳体外围的紧固件相铰接。
本发明超声碎石方法及超声碎石钳的工作机理，利用夹具抓握住结石，使其无法在患者体内滑动，使超声碎石器可定向碎石，不仅避免了超声器对其它健康组织造出的损伤，而且有利于大大缩短碎石的时间，减少患者的疼痛。
 
附图说明
图1为本发明超声碎石钳的立体示意图；
图2为本发明超声碎石钳的裂解图；
图3为本发明超声碎石钳的剖面示意图（弹性体自然状态）；
图4为本发明超声碎石钳的剖面示意图（弹性体压缩状态）。
 
具体实施方式
本发明超声碎石方法，利用在体内超声碎石器前部设有一可牢固夹持人体内结石的夹具，以利于超声碎石器准确定位后超声碎石。
为了方便结石的定位和设计的合理性，上述夹具为可伸张和收合的夹具；也可以是爪形夹具，或者为负压吸结石夹具。
本发明超声碎石方法的工作机理，利用夹具抓握住结石，使其无法在患者体内滑动，使超声碎石器可定向碎石，不仅避免了超声器对其它健康组织造出的损伤，而且有利于大大缩短碎石的时间，减少患者的疼痛。
利用上述方法设计而成的一种超声碎石钳，包括碎石钳主体1，主体1包括用于夹持结石的结石钳体2、用于支撑结石钳体2以使钳口张、合的支撑柄体4，以及发生超声波的能量器5。
上述结石钳体2为一根细杆，细杆端头部自然状态下呈两张开的瓣体6。
上述支撑柄体4包括设置在其前端部的结石钳体撑管7，和以让结石钳体2在支撑柄体体内伸缩的推拉柄8，所述推拉柄包括呈U型的弹性体9，所述弹性体的U形一端部铰接连接在支撑柄体上，另一端部与套置在结石钳体2外围的紧固件10相铰接。
本发明超声碎石钳的工作使用过程，首先将结石钳体套装入支撑柄体中，由紧固件夹紧结石钳体（如图1、3所示），当使用者按压U型的弹性体时，U型开口缩小（如图4所示），即推动结石钳体头部沿结石钳体撑管外伸，此时，结石钳体端头部的两瓣体处于自然分开状态，使用者对准使结石位于两瓣体中间位置，使用者放松U型的弹性体，U型开口变大，结石钳体即夹紧结石，此时，该超声波的能量器就可定向对该结石进行超声碎石。
以上所述仅为本发明的较佳实施例，凡依本发明申请专利范围所做的均等变化与修饰，皆应属本发明的涵盖范围。
