Abstract

A surgical device comprising an end effector is disclosed. The surgical device comprises a trigger actuatable to cause the end effector to be energized and a circuit in communication with the trigger. The circuit is configured to, when a first level of force is applied to the trigger, drive the end effector at a first level, when a second level of force is applied to the trigger, drive the end effector at a second level, and, delay by a first period of time between indicating a change in the force applied to the trigger from the first level of force to the second level of force and a change from driving the end effector at the first level to driving the end effector at the second level, wherein the first period of time is sufficient to give a user a warning about the change in the force.
