Abstract
A surgical instrument including a firing drive configured to selectively advance a firing member and/or cutting member relative to an end effector and, in addition, a reversing drive configured to selectively retract the firing member and/or cutting member relative to the end effector. The firing drive can include a pawl which can be selectively engaged with the firing member in order to advance the firing member, wherein the pawl can be disengaged from the firing member when the reversing drive is engaged with the firing member. The reversing drive can include a gear train having a first gear operably engaged with the firing member and, in addition, a second gear operably engaged with the first gear, wherein the second gear can be selectively operable with the trigger such that an actuation of the trigger can retract the firing member and/or cutting element via the first and second gears.
