A surgical clip applying apparatus includes a movable member biased in the housing adjacent the wedge plate. An actuator longitudinally advances the wedge plate a predetermined distance to a distal most position. The wedge plate has an end being disposed between first and second jaw portions at the distal most position. The wedge plate end is configured to maintain the jaw assembly in the spaced apart position during loading of the surgical clip and reduce torque and external forces on the jaw assembly during the loading. The movable member holds the wedge plate in the distal most position during the loading and the movable member is deflected at a conclusion of the loading, releases the wedge plate upon deflection, and allows a longitudinal proximal retraction of the wedge plate from the distal most position.

1. An apparatus for application of surgical clips to body tissue, the apparatus comprising: a handle portion;a body extending distally from the handle portion and defining a longitudinal axis;a jaw assembly mounted adjacent a distal end portion of the body, the jaw assembly including first and second jaw portions movable between a spaced-apart and an approximated position;a jaw closure member positioned adjacent the first and second jaw portions to move the jaw portions to the approximated position;a plurality of surgical clips disposed within the body;a clip pusher disposed proximal to the plurality of clips and configured to bias the plurality of clips in a distal manner;a feed bar configured to individually distally advance a surgical clip to the jaw assembly while the jaw portions are in the spaced apart position;a wedge plate longitudinally movable between the first and the second jaw portions;an actuator at least partially disposed within the body and longitudinally movable in response to actuation of the handle portion, wherein the actuator comprises a cam, and the wedge plate has a first cam slot and a first camming surface to engage with the cam to move the wedge plate distally between the first and second jaw portions upon a distal advancement of the actuator; anda slider joint, the slider joint and the jaw closure member being in substantially coaxial alignment with the actuator, wherein the slider joint couples the actuator to the jaw closure member, wherein the slider joint provides partial movement of the actuator with respect to the jaw closure member and provides distal movement of the jaw closure member upon distal movement of the actuator beyond a predetermined point. 2. The apparatus of claim 1, further comprising a filler plate having a second cam slot and a second camming surface causing the cam to disengage from the wedge plate, upon a distal advancement of the actuator, thereby allowing the wedge plate to move proximally. 3. The apparatus of claim 1, wherein the filler plate is stationary with respect to the body. 4. The apparatus of claim 1, wherein the wedge plate has a rounded distal end configured to compress at least a portion of the jaw assembly. 5. The apparatus of claim 1, wherein the actuator further actuates a signal device, the signal device providing an identification that at least one of the plurality of clips has fired. 6. The apparatus of claim 5, wherein the signal device is a visual display. 7. The apparatus of claim 5, wherein the signal device is an audible device. 8. The apparatus of claim 1, further comprising a lockout mechanism to prevent the apparatus from actuating after the last of the plurality of clips has been fired. 9. An apparatus for application of surgical clips to body tissue, the apparatus comprising: a handle portion;a tubular member extending distally from the handle portion and defining a longitudinal axis, the tubular member being longitudinally fixed with respect to the handle portion, the tubular member being configured to rotate about the longitudinal axis;a spindle extending through the tubular member, the spindle having a proximal end and a distal end, the spindle being configured for movement along the longitudinal axis, the movement of the spindle defining a stroke, the stroke defining a predetermined distance of spindle travel from a proximal most position to a distal most position;a slider joint extending along the distal end of the spindle, the spindle being configured to provide movement of the slider joint along the longitudinal axis;a feed bar located within the tubular member and extending parallel to the longitudinal axis, the spindle being operatively connected with and configured to move the feed bar along the longitudinal axis; anda wedge plate located within the tubular member and extending parallel to the longitudinal axis, the spindle being operatively connected with and configured to move the wedge plate along the longitudinal axis;wherein the stroke of the spindle defines a first distal stroke portion, wherein the first distal stroke portion of the spindle provides distal movement of both the wedge plate and the feed bar;wherein the stroke of the spindle defines a second distal stroke portion, wherein the second portion of the spindle provides proximal movement of the wedge plate and the feed bar;wherein the slider joint is configured to remain stationary with respect to the spindle during the first and second distal stroke portions of the spindle. 10. The apparatus of claim 9, further comprising a jaw assembly mounted adjacent a distal end portion of the tubular member, the jaw assembly being longitudinally fixed with respect to the tubular member and including a first jaw portion and a second jaw portion, each jaw portion being movable between a spaced-apart position and an approximated position. 11. The apparatus of claim 10, further comprising a driver bar being attached to the slider joint and positioned adjacent the first and second jaw portions to move the jaw portions to the approximated position upon a distal advancement of the slider joint. 12. The apparatus of claim 11, wherein the stroke of the spindle defines a third distal stroke portion, wherein the third distal stroke portion of the spindle provides distal movement of both the slider joint and the drive bar. 13. The apparatus of claim 9, further comprising a filler plate located between the wedge plate and the feed bar, the filler plate being fixed in position with respect to the tubular member. 14. The apparatus of claim 9, further comprising a plurality of clips disposed within the tubular member. 15. The apparatus of claim 14, further comprising a lockout mechanism configured to prevent movement of the spindle after a last of the plurality of clips has been fired. 16. The apparatus of claim 9, wherein the wedge plate is configured to be longitudinally movable between the first and the second jaw portions upon a distal advancement of the spindle.
