Abstract

A surgical instrument that includes an end effector and a trigger that is actuatable between a first position and a second position. An actuation drive is movable between an unactuated position and an actuated position in response to actuation of the trigger. A toggle assembly is transitionable between a folded configuration and an expanded configuration, wherein the toggle assembly is configured to motivate the actuation drive to effectuate a movement in the end effector in the folded configuration. The toggle assembly being configured to bypass the actuation drive when in the expanded configuration. A resetting member is operable to return the toggle assembly to the folded configuration.
