Abstract

A surgical instrument includes an end effector and a handle assembly. The end effector is configured to operate at a first energy level and at a second energy level. The end effector is further configured to transition between an open position and a closed position. The end effector is configured to grasp tissue in the closed position. The handle assembly includes a body, a trigger, and an activation element. The trigger is configured to pivot in a first direction relative to the body to actuate the end effector from the open position to the closed position. The activation element is configured to activate the end effector at either the first energy level or the second energy level. The trigger is configured to either activate the activation element or determine whether the end effector operates at the first energy level or the second energy level.
