1. An apparatus for application of surgical clips to body tissue, the apparatus comprising: a handle assembly including a trigger and a drive bar, the drive bar being reciprocally translatable by the trigger upon a firing stroke thereof;a shaft assembly extending distally from the handle assembly and defining a longitudinal axis, the shaft assembly including: a housing having a stationary feature projecting therefrom;a plurality of surgical clips disposed within the housing;a jaw mounted adjacent a distal end portion of the housing, the jaw being movable between an open spaced-apart condition and a closed approximated condition;a pusher bar reciprocally disposed within the housing, the pusher bar being configured to load a distal-most surgical clip into the jaws while the jaws are in the open condition and remain in a distal-most position during an approximation of the jaws, the pusher bar including a spring clip supported thereon for detachably connecting to the stationary feature of the housing when the push bar is at the distal-most position;a wedge plate reciprocally disposed within the housing, the wedge plate being movable between a position where a distal end thereof is disposed in the jaws and a position where the distal end thereof is free from the jaws; anda connector plate reciprocally disposed within the housing, wherein the connector plate detachably connects to each of the pusher bar and the wedge plate during at least a portion of the firing stroke of the trigger. 2. The apparatus according to claim 1, wherein the pusher bar includes a further spring clip supported thereon for detachably connecting to a first feature provided on the connector plate, and the wedge plate includes a spring clip supported thereon for detachably connecting to a second feature provided on the connector plate. 3. The apparatus according to claim 2, wherein the spring clip of the wedge plate is connected to the second feature of the connector plate during an initial distal movement of the connector plate to pull the wedge plate in a distal direction such that the distal end of the wedge plate is disposed in the jaws. 4. The apparatus according to claim 2, wherein the second feature of the connector plate disconnects from the spring clip of the wedge plate following an initial distal movement of the wedge plate. 5. The apparatus according to claim 2, wherein the spring clip of the pusher bar is connected to the first feature of the connector plate during an initial distal movement of the connector plate to pull the pusher bar in a distal direction. 6. The apparatus according to claim 5, wherein the stationary feature of the housing blocks distal movement of the pusher bar beyond the initial distal movement, and wherein the first feature of the connector plate disconnects from the spring clip of the pusher bar upon continued distal movement beyond the initial distal movement. 7. The apparatus according to claim 1, wherein the connection of the spring clip of the pusher bar and the stationary feature of the housing maintains the pusher bar at the distal-most position thereof during the firing stroke of the trigger. 8. The apparatus according to claim 1, wherein the wedge plate is moved in a proximal direction at a time prior to an approximation of the jaws to free the jaws of the distal end of the wedge plate. 9. The apparatus according to claim 1, wherein the pusher bar and the wedge plate each disconnect from the connector plate following an initial distal movement of each of the pusher bar and the wedge plate. 10. The apparatus according to claim 9, wherein each of the pusher bar and the wedge plate re-connect with the connector plate upon a respective proximal movement thereof. 11. The apparatus according to claim 1, wherein the shaft assembly includes an advancer plate reciprocally disposed within the housing, adjacent to the pusher bar, the advancer plate including at least one fin engageable by a shoulder of the pusher bar, wherein the shoulder of the pusher bar engages the at least one fin of the advancer plate during a distal and a proximal movement of the pusher bar to effectuate one of a distal and proximal movement of the advancer plate. 12. The apparatus according to claim 11, wherein the shaft assembly includes a clip carrier disposed within the housing adjacent the advancer plate, wherein the clip carrier is configured to retain the plurality of surgical clips. 13. The apparatus according to claim 12, wherein the shaft assembly includes a clip follower slidably supported in the clip carrier at a location proximal of the plurality of surgical clips, the clip follower being configured to urge the plurality of surgical clips in a distal direction, the clip follower including a first tab projecting from a first surface thereof and a second tab projecting from a second surface thereof, wherein the first tab of the clip follower engages the advancer plate as the advancer plate is moved distally such that the clip follower is moved distally to advance the plurality of surgical clips, and wherein the second tab of the clip follower engages the clip follower as the advancer plate is moved proximally such that the clip follower remains stationary. 14. The apparatus according to claim 13, wherein the clip follower includes a catch extending from a surface thereof, wherein the catch engages the pusher bar following firing of a last surgical clip and prevents movement of the pusher bar in a proximal direction. 15. The apparatus according to claim 1, wherein the shaft assembly includes a drive channel reciprocally disposed within the housing adjacent a clip carrier, the clip carrier configured to retain the plurality of surgical clips, wherein the drive bar selectively engages the drive channel to effect translation of the drive channel, wherein a distal end of the drive channel engages a surface of the jaws upon distal advancement thereof to effectuate approximation of the jaws. 16. The apparatus according to claim 15, wherein the shaft assembly includes a wedge plate lock, wherein the drive channel actuates the wedge plate lock upon distal advancement thereof to cause proximal movement of the wedge plate to withdraw the distal end of the wedge plate from the jaws and permit the drive channel to approximate the jaws. 17. The apparatus according to claim 1, wherein the handle assembly further includes an indicator supported therein, wherein the indicator provides at least one of an audible and a tactile indication when at least one of a surgical clip is loaded into the jaws, a surgical clip is fired and the apparatus is re-set. 18. The apparatus according to claim 1, wherein the wedge plate is biased to a proximal position. 19. An apparatus for application of surgical clips to body tissue, the apparatus comprising: a handle assembly including a trigger and a drive bar, the drive bar reciprocally translatable by the trigger upon a firing stroke thereof;a shaft assembly extending distally from the handle assembly and defining a longitudinal axis, the shaft assembly including: a housing;a plurality of surgical clips disposed within the housing;a jaw mounted adjacent a distal end portion of the housing, the jaw being movable between an open spaced-apart condition and a closed approximated condition;a pusher bar reciprocally disposed within the housing, the pusher bar being configured to load a distal-most surgical clip into the jaws while the jaws are in the open condition and remain in a distal-most position during an approximation of the jaws;a wedge plate reciprocally disposed within the housing, the wedge plate being movable between a position where a distal end thereof is disposed in the jaws and a position where the distal end thereof is free from the jaws, the wedge plate including a spring clip supported thereon,a connector plate reciprocally disposed within the housing, wherein the connector plate detachably connects to each of the pusher bar and the wedge plate during at least a portion of the firing stroke of the trigger, the spring clip of the wedge plate connected to a feature of the connector plate during an initial distal movement of the connector plate to pull the wedge plate in a distal direction such that the distal end thereof is disposed in the jaws. 20.
