Description

组织消融、切割及融合系统 技术领域
本发明涉及一种电外科手术器械，特别是外科手术中使用的组织消融、切割和融合使用的手术器械。
背景技术
外科手术中，组织的消融、切割和融合是非常重要的组织处理过程，目前常用的组织消融、切割和融合技术中，电加热组织消融方法是其中重要的技术之一，通过对组织加热，造成蛋白质的改性，从而实现组织的消融、切割和融合过程。
目前的电加热组织消融方法中，轴杆有多种运动，如通过轴杆的平移运动来实现工作面的闭合和打开动作，通过轴杆的旋转运动来实现工作面的旋转运动。在这些运动过程中，系统内的电路系统也需要随之发生平移往复运动和旋转运动以保证电路系统的接通。而这些频繁的运动对于电路接口的影响很大，非常容易导致接线点因往复运动产生的疲劳断裂而造成电路接线点的脱落，造成器械断电，从而造成手术过程的中断，存在临床使用安全隐患。
因此，需要对现有技术的组织消融、切割和融合系统进行改进，尤其是需要对其电路系统进行进一步的改进。

所述轴杆21含内杆21-1和外杆21-2；所述工作面31分别连接在所述内杆21-1和外杆21-2的远端；当所述内杆21-1向近端运动时，所述工作面31闭合；当所述内杆21-1向远端运动时，所述工作面31打开。转动所述旋钮23可驱动所述内杆21-1和所述外杆21-2转动，进而驱动所述工作面31进行旋转运动。
