Electrosurgical devices

摘要

In one embodiment, a surgical instrument comprises a handle assembly. The handle assembly comprises a closure trigger defining an energy button hole, an energy button located within the energy button hole, and a firing trigger. A shaft assembly is coupled to the handle assembly and comprises an outer tube, a closure actuator coupled to the closure trigger, and a firing actuator operatively coupled to the firing trigger. An end effector is coupled to a distal end of the shaft assembly. The end effector comprises a jaw assembly having a proximal end and a distal end. The jaw assembly comprises a first and a second jaw member. The first and second jaw members define a longitudinal slot. The closure actuator is coupled to the first jaw member to pivotally move the first jaw member from an open position to a closed position. A cutting member is deployable within the longitudinal slot.
