1. A stapling device comprising:
a handle assembly;
an elongate body including a proximal portion and a distal portion, the proximal portion extending distally from the handle assembly;
an end effector operably disposed on the distal portion of the elongate body, the end effector including a first jaw member and a second jaw member pivotally secured relative to the first jaw member and movable between an open position and a closed position, the first jaw member including at least one pusher bag, the at least one pusher bag being transformable between a deflated condition and an expanded condition; and
at least one staple member releasably supported within the first jaw member, wherein transformation of the at least one pusher bag from the deflated condition to the expanded condition ejects the at least one staple member from the first jaw member,
wherein the handle assembly includes a handle member and a gas release mechanism, and the stapling device further includes a drive assembly that is coupled to the handle member, the handle member movable from a first position to a second position to actuate the drive assembly to move the first jaw member from the open position to the closed position, the handle member movable from the second position to a third position to actuate the gas release mechanism to supply pressurized gas to the at least one pusher bag.
