In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A firing member reciprocates within an elongate shaft to the end effector to transfer this firing motion. A retraction spring retracts the firing member after full firing. Between firing strokes as the firing trigger is released, an anti-backup mechanism activates an electrical actuator (e.g., elecroactive polymer actuator) that is physically grounded to the handle to bind the firing member preventing inadvertent retraction.
a locking plate of the electrical actuator having a through hole encompassing the firing member, the locking plate through hole sized for the locking plate to be in nonbinding contact with the firing member when the locking plate is in an unlocked state perpendicular to the firing member, and for the locking plate to be in binding contact with the firing member when the locking plate is in a locked state when tipped at an angle from perpendicular, the electrical actuator positioned to move the locking plate from a selected state to the other state of a group consisting of the unlocked state and the locked state.
