1. A directed energy surgical instrument comprising:
- a handle assembly comprising a body portion and a handle portion, the body portion and handle portion arranged in a pistol-shaped configuration;
an elongate transmission assembly attached to the body portion of the handle assembly and extending distally therefrom, the transmission assembly comprising a tubular sheath member attached at its proximal end to the body portion, an actuating member disposed within the tubular sheath member, and an end-effector assembly attached to the actuating member adjacent the distal end of the tubular sheath member, the end effector assembly comprising a blade member and a clamp member that is pivotable relative to the blade member, wherein the actuating member is configured for transmitting energy from the handle assembly to the end effector assembly;
a trigger mounted to the handle portion, the trigger being configured so that a portion of the trigger extends distally from a distal surface of the handle portion and being operatively connected to the actuating member so that motion of the trigger causes the clamp member to pivot relative to the blade member; and
an activation mechanism adapted to control the transmission of energy to the end effector assembly, wherein the activation mechanism is located on the distal surface of the handle portion intermediate the trigger and the body portion.
