First Claim
1. An electrosurgical device comprising:
- forceps including;
i. a first working arm including an arm securing mechanism;
ii. a second working arm including an arm securing mechanism; and
iii. a slider including an immobilization member that is extendable between the arm securing mechanism of the first working arm and the arm securing mechanism of the 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 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 the immobilization member extending between the arm securing mechanism of the first working arm and the arm securing member of the second working arm so that movement of the first working arm and the second working arm towards each other is prevented; and
C. a third mechanical configuration where the first working arm and second working arm are secured together by the immobilization member extending between the arm securing mechanism of the first working arm and the arm securing mechanism of the second working arm so that the first working arm and the second working arm are prevented from moving towards each other, and the blade is substantially flush with or extends 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.
