可重构电外科设备
摘要：
一种电外科设备包括：夹钳，该夹钳包括：(i)第一作业臂；以及(ii)第二作业臂；刀片；其中，所述电外科设备能够在如下之间切换：(A)第一机械构造，在此第一机械构造中，所述第一作业臂与所述第二作业臂自由地沿朝向彼此的方向移动以抓取其间的组织；(B)第二机械构造，在此第二机械构造中，所述第一作业臂与所述第二作业臂被臂固定机构固定在一起，所述臂固定机构阻止所述第一作业臂与所述第二作业臂沿朝向彼此的方向移动；以及(C)第三机械构造，在此第三机械构造中，所述第一作业臂与所述第二作业臂固定在一起，使得所述第一作业臂与所述第二作业臂被阻止沿朝向彼此的方向移动，并且所述刀片与所述第一作业臂与所述第二作业臂的远端基本平齐或者延伸超出所述第一作业臂与所述第二作业臂的所述远端；并且其中，所述电外科设备构造成：当所述电外科设备呈所述第一机械构造与所述第二机械构造时，在所述第一作业臂与所述第二作业臂之间递送双极电流，并且阻止电流从所述刀片流动；以及当所述电外科设备呈所述第三机械构造时通过所述刀片递送电流。
摘要（英）：

An electrosurgical device comprising: forceps including: a first working arm and (ii) a second working arm; a blade; wherein the electrosurgical device is capable of being switched between: (A) a first mechanical configuration where the first working arm and second working arm are free to move in a direction towards each other to grasp tissue therebetween; (B) a second mechanical configuration where the first working arm and second working arm are secured together by an arm securing mechanism that prevents movement of the first working arm and the second working arm in a direction towards each other; and (C) a third mechanical configuration where the first working arm and second working arm are secured together so that the first working arm and the second working arm are prevented from moving in a direction towards each other, and the blade is substantially flush with or extend beyond a distal end of the first working arm and the second working arm; and wherein the electrosurgical device is configured to; deliver a bipolar current between the first working arm and the second working arm, and to prevent current from flowing from the blade when the electrosurgical device is in the first mechanical configuration and the second mechanical configuration; and deliver current through the blade when the electrosurgical device is in the third mechanical configuration.
