    e) a wedge plate longitudinally movable between the first and the second jaw portions;

    wherein said wedge plate biases the first and the second jaw portions when said wedge plate is longitudinally moved between the first and the second jaw portions;

    wherein said wedge plate maintains the first and the second jaw portions in the spaced-apart position and preventing flexing of the first and the second jaw portions during clip loading; and

    wherein said wedge plate has a first proximal window, said first proximal window to be engaged by a member disposed in said body, said member being configured to hold said wedge plate in a distal most position, said distal most position being between the first and the second jaw portions;

    f) a clip pusher configured to individually distally advance a surgical clip to the jaw assembly while the first and the second jaw portions are in the spaced-apart position;

    g) an actuator at least partially disposed within the body and longitudinally movable in response to actuation of the handle portion, the actuator having a cam link; and
