First Claim
1. A surgical instrument comprising:
- a handle assembly comprising;
a first handle housing located on a first side of the handle assembly and a second handle housing located on a second and opposing side of the handle assembly;
a closure trigger defining an energy button hole;
an energy button comprising a first end and a second end located within the energy button hole and extending through the handle assembly, wherein the first energy button end is accessible from the first handle housing and the second energy button end is accessible from the second handle housing; and
a firing trigger;
a shaft assembly coupled to the handle assembly, the shaft assembly comprising;
an outer tube;
a closure actuator operatively coupled to the closure trigger; and
a firing actuator operatively coupled to the firing trigger; and
an end effector coupled to a distal end of the shaft assembly, the end effector comprising;
a jaw assembly having a proximal end and a distal end, the jaw assembly comprising;
a first jaw member; and
a second jaw member, wherein the first and second jaw members define a longitudinal slot, wherein 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 relative to the second jaw member; and
a cutting member deployable within the longitudinal slot, wherein the cutting member is coupled to the firing actuator to advance the cutting member distally within the longitudinal slot.

Abstract
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.
