1. An apparatus for application of surgical clips to body tissue, the apparatus comprising: a handle assembly;a shaft assembly including a housing extending distally from the handle assembly and defining a longitudinal axis, the housing including a fixed boss provided therein;a plurality of surgical clips disposed within the shaft assembly;a pair of jaws mounted adjacent a distal end portion of the shaft assembly, the pair of jaws being movable between an open spaced-apart condition and a closed approximated condition; anda pusher bar reciprocally disposed within the housing of the shaft assembly, wherein the pusher bar includes a first spring clip fixedly supported thereon that is configured to detachably snap onto the boss provided in the housing of the shaft assembly, the pusher bar configured to contact a distal-most surgical clip to load the distal-most surgical clip into the pair of jaws during distal movement and remain connected to the boss of the housing of the shaft assembly and to remain in a distally advanced position during an approximation of the pair of jaws, and wherein the first spring clip includes a pair of spaced apart tines and defines a concave recess formed in an inner surface of each of the pair of spaced apart tines, wherein the concave recesses are configured to receive the boss. 2. The apparatus according to claim 1, wherein the pusher bar includes a pusher formed at a distal end thereof, wherein the pusher has a narrow profile for contacting the loaded surgical clip at a single location. 3. The apparatus according to claim 2, wherein the pusher defines a plane that is oriented substantially orthogonal to a plane of the loaded surgical clip. 4. The apparatus according to claim 1, further comprising a connector plate reciprocally disposed within the shaft assembly, wherein the connector plate is detachably connectable to the pusher bar, wherein during an initial distal movement of the connector plate the pusher bar is distally advanced and during a further distal movement of the connector plate the connector plate is disconnected from the pusher bar. 5. The apparatus according to claim 4, further comprising an advancer plate reciprocally disposed within the shaft assembly, the advancer plate including at least one fin detachably connectable to 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. 6. The apparatus according to claim 1, further comprising a counter supported in the housing assembly, wherein the counter provides an indication when a surgical clip has been fired. 7. The apparatus according to claim 1, wherein the pair of spaced apart tines define a gap therebetween which is less than a diameter of the boss provided in the housing of the shaft assembly, and wherein the concave recesses are in juxtaposed relation to one another. 8. A method of applying surgical clips to body tissue, comprising the steps of: providing an apparatus for application of surgical clips to body tissue including: a handle assembly;a shaft assembly including a housing extending distally from the handle assembly and defining a longitudinal axis, the housing including a fixed boss provided therein;a plurality of surgical clips disposed within the shaft assembly;a pair of jaws mounted adjacent a distal end portion of the shaft assembly, the pair of jaws being movable between an open spaced-apart condition and a closed approximated condition; anda pusher bar reciprocally disposed within the housing of the shaft assembly, wherein the pusher bar includes a first spring clip fixedly supported thereon that is configured to detachably snap onto the boss provided in the housing of the shaft assembly, the pusher bar configured to contact a distal-most surgical clip to load the distal-most surgical clip into the pair of jaws during distal movement and remain connected to the boss of the housing of the shaft assembly and to remain in a distally advanced position during an approximation of the pair of jaws, wherein the first spring clip includes a pair of spaced apart tines and defines a concave recess formed in an inner surface of each of the pair of spaced apart tines, wherein the concave recesses are configured to receive the boss;advancing the pusher bar within the housing of the shaft assembly;loading a distal-most surgical clip into the pair of jaws;connecting the first spring clip to the boss provided in the housing of the shaft assembly; andapproximating the pair of jaws while maintaining the connection of the first spring clip to the boss, thereby maintaining the pusher bar in the distally advanced position during approximation of the pair of jaws, wherein approximation of the pair of jaws forms the distal-most surgical clip. 9. The method according to claim 8, wherein loading the distal-most surgical clip further includes contacting a pusher formed at a distal end of the pusher bar with the loaded surgical clip at a single location. 10. The method according to claim 8, wherein advancing the pusher bar further includes: distally advancing a connector plate that is reciprocally disposed within the shaft assembly, during an initial distal movement of the connector plate; anddisconnecting the connector plate from the pusher bar during a further distal movement of the connector plate. 11. The method according to claim 10, wherein advancing the pusher bar further includes engaging a second spring clip supported thereon with a first feature of the connector plate, and disengaging the first feature of the connector plate from the second spring clip following the initial distal movement of the connector plate. 12. The method according to claim 10, wherein advancing the pusher bar further includes reciprocating an advancer plate reciprocally within the shaft assembly, wherein the advancer plate includes at least one fin detachably connectable to a shoulder of the pusher bar, and engaging the shoulder of the pusher bar with 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 or proximal movement of the advancer plate. 13. The method according to claim 12, wherein advancing the pusher bar further includes a clip follower, slidably supported in the shaft assembly, urging 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 during a moving of the advancer plate distally, the first tab of the clip follower engages the advancer plate such that the clip follower is moved distally to advance the plurality of surgical clips, and wherein during a moving of the advancer plate proximally, the second tab of the clip follower engages a feature as the advancer plate such that the clip follower remains stationary. 14. An apparatus for application of surgical clips to body tissue, the apparatus comprising: a handle assembly;a shaft assembly including a housing extending distally from the handle assembly and defining a longitudinal axis, the housing includes a fixed boss provided therein;a plurality of surgical clips disposed within the shaft assembly;a pair of jaws mounted adjacent a distal end portion of the shaft assembly, the pair of jaws being movable between an open spaced-apart condition and a closed approximated condition; anda pusher bar reciprocally disposed within the housing of the shaft assembly and configured to detachably snap onto the boss of the housing of the shaft assembly when in a distally advanced position, the pusher bar being configured to contact a distal-most surgical clip and progress to the distally advanced position to load the distal-most surgical clip into the pair of jaws during distal movement and remain connected to the boss of the housing of the shaft assembly and in the distally advanced position during an approximation of the pair of jaws, wherein the pusher bar includes a spring clip fixedly connected thereto and being configured to detachably snap connect the pusher bar to the boss of the housing of the shaft assembly, and wherein the spring clip includes a pair of spaced apart tines and defines a concave recess formed in an inner surface of each of the pair of spaced apart tines, wherein the concave recesses are configured to receive the boss. 15. The apparatus according to claim 14, wherein the pair of spaced apart tines define a gap therebetween which is less than a diameter of the boss provided in the housing of the shaft assembly, and wherein the concave recesses are in juxtaposed relation to one another.
