    a first jaw closure system operably interfacing with the elongated channel and configured to selectively move the elongated channel relative to the anvil;

    a second jaw closure system independently operable from the first jaw closure system, wherein the second jaw closure system operably interfacing interfaces with the anvil and is configured to selectively move the anvil relative to the elongated channel; and
