Description

一种按压开关式的球囊压力泵及应用
技术领域
本发明属于医疗器具技术领域，具体涉及一种按压开关式的球囊压力泵及应用。
背景技术
介入治疗及手术作为目前较为先进且有效的血管疾病诊治方法，发展非常迅速。球囊压力泵是介入治疗及手术中用于向球囊扩张导管加压，使得球囊扩张，以达到扩张血管或在血管内留置支架目的的医疗器械。
现有的球囊压力泵在加压、泄压、负压等操作过程中不够方便，键位设置单一，容易误操作，可靠性差。
发明内容
本发明提供了一种按压开关式的球囊压力泵及应用，具体技术方案如下：
一种按压开关式的球囊压力泵，包括压力表1、外管2、螺杆3、托盖4、托体5、开关按钮6和螺杆释放锁紧装置；压力表1、外管2、托体5依次相连，螺杆3由外管2的后端口伸入外管2内，托盖4和托体5配合使用，开关按钮6位于托盖4上；所述螺杆释放锁紧装置包括开关锁杆7、左锁块8、右锁块9、左形变块10、右形变杆11、形变开关12和四个螺钉；开关锁杆7的两侧，左锁块8和右锁块9对称分布，右形变杆11与开关锁杆7轴向平行，形变开关12位于右形变杆11与左变形块10之间，横跨在螺杆3上方。
如上所述的一种按压开关式的球囊压力泵的应用：利用开关按钮6向下压迫形变开关12，使右形变杆11中心向外变形，利用杠杆原理迫使左锁块8、右锁块9向螺杆3方向移动，压迫螺杆3使螺杆上螺纹与锁块上螺纹咬合，完成锁紧动作；再次按压开关按钮6另一端，释放形变开关12，使右形变杆11变形恢复，左锁块8和右锁块9均离开螺杆3，释放螺杆的动作。
本发明利用开关按钮以实现螺杆释放与锁紧的动作，大大方便了使用者的操作；且开关采用按钮的形式，方便易懂，减少了使用者的误操作。
附图说明
图1为按压开关式的球囊压力泵示意图；其中，图1(a)为球囊压力泵整体图，图1(b)为螺杆释放锁紧装置的结构示意图；
其中，1-压力表、2-外管、3-螺杆、4-托盖、5-托体、6-开关按钮、7-开关锁杆、8-左锁块、9-右锁块、10-左形变块、11-右形变杆、12-形变开关。
具体实施方式
下面结合附图和具体实施例对本发明作进一步的说明，但并不因此而限制本发明的保护范围。
如图1所示的一种按压开关式的球囊压力泵，包括压力表1、外管2、螺杆3、托盖4、托体5、开关按钮6和螺杆释放锁紧装置；压力表1、外管2、托体5依次相连，螺杆3由外管2的后端口伸入外管2内，托盖4和托体5配合使用，开关按钮6位于托盖4上；所述螺杆释放锁紧装置包括开关锁杆7、左锁块8、右锁块9、左形变块10、右形变杆11、形变开关12和四个螺钉；开关锁杆7的两侧，左锁块8和右锁块9对称分布，右形变杆11与开关锁杆7轴向平行，形变开关12位于右形变杆11与左变形块10之间，横跨在螺杆3上方。
如上所述的一种按压开关式的球囊压力泵的应用：利用开关按钮6向下压迫形变开关12，使右形变杆11中心向外变形，利用杠杆原理迫使左锁块8、右锁块9向螺杆3方向移动，压迫螺杆3使螺杆上螺纹与锁块上螺纹咬合，完成锁紧动作；再次按压开关按钮6另一端，释放形变开关12，使右形变杆11变形恢复，左锁块8和右锁块9均离开螺杆3，释放螺杆的动作。
