Abstract

A surgical instrument that has an actuation system that is configured to generate at least two separate actuation motions. A clutch assembly is movable between an engaged position wherein the clutch assembly is in operable engagement with the actuation system and an unengaged position. In various forms, the surgical instrument includes a manually actuatable trigger assembly that interfaces with the clutch assembly and the actuation system such that a first stroke of the trigger assembly causes the actuation system to generate a first one of the actuation motions and moves the clutch assembly from the unengaged position to the engaged position whereupon a second stroke of the trigger assembly causes the actuation system to generate another one of the actuation motions.
