A surgical apparatus for application of surgical clips to body tissue is provided. The surgical apparatus includes a housing, a drive assembly, a trigger, and a shaft assembly. The trigger is operatively connected with the drive assembly. The drive assembly is at least partially positioned within the housing. The shaft assembly extends distally from the housing and has a first tubular member pivotally connected with a second tubular member located distally from the first tubular member. An articulation mechanism is operatively connected between the first and second tubular members, and includes a gear rack, at least one gear, and a gear segment, respectfully connected with each other to pivot the second tubular member about the pivot axis. The gear rack and at least one gear are located within the first tubular member. The gear segment extends proximally from the second tubular member.

1. A surgical clip applying apparatus for application of surgical clips to body tissue, the apparatus comprising: a housing;a drive assembly at least partially positioned within the housing;a shaft assembly extending distally from the housing and having a first tubular member and a second tubular member located distally from the first tubular member, the first tubular member defining a longitudinal axis, the second tubular member supporting a plurality of surgical clips and configured to distally advance each single clip of the plurality of surgical clips, individually, to form the single clip of the plurality of surgical clips upon each single firing of the surgical clip applying apparatus, the first tubular member and the second tubular member being pivotally connected through a common pivot axis, the pivot axis being perpendicular to the longitudinal axis;wherein the second tubular member includes a jaw assembly having a pair of juxtaposed jaws, the jaw assembly having a spaced apart condition for entirely receiving a single unformed clip between the pair of jaws, and an approximated condition wherein the pair of jaws form the single clip disposed therebetween, wherein the second tubular member defines a longitudinal axis, and wherein the pair of jaws are approximated in a direction transverse to the longitudinal axis of the second tubular member; andan articulation mechanism operatively connected between the first tubular member and the second tubular member, the articulation mechanism including: a gear rack having a plurality of teeth longitudinally placed thereon, the gear rack located within the first tubular member; andat least one gear operatively connected with the gear rack located within the first tubular member; anda gear segment extending proximally from the second tubular member, the gear segment being fixed with respect to the second tubular member, the gear segment being operatively connected with the at least one gear to pivot the second tubular member about the pivot axis. 2. The surgical clip applying apparatus according to claim 1, wherein the articulation mechanism pivots the second tubular member about the pivot axis at an angle of up to 90° from the longitudinal axis. 3. The surgical clip applying apparatus according to claim 1, further comprising a rotation mechanism, the rotation mechanism including a dial and a band located about a proximal portion of the drive assembly, the dial defining an internal passage and an inner surface, the band defining a contoured outer surface configured to receive and transmit a rotational force from the inner surface of the dial to the portion of the drive assembly. 4. The surgical clip applying apparatus according to claim 3, wherein the dial is slidably coupled with the band to permit longitudinal movement of the drive assembly with respect to the dial. 5. The surgical clip applying apparatus according to claim 1, wherein the drive assembly includes a flexible cable to transfer both a translational force and a rotational force into the second tubular member. 6. The surgical clip applying apparatus according to claim 1, wherein the second tubular member includes two substantially parallel gear segments. 7. The surgical clip applying apparatus according to claim 1, wherein the second tubular member includes a clip cartridge containing a plurality of clips disposed therein. 8. The surgical clip applying apparatus according to claim 1, further comprising a rotation mechanism, the rotation mechanism being operatively connected with and providing a rotational force to the jaw assembly. 9. The surgical clip applying apparatus according to claim 1, wherein the articulating mechanism includes a control knob being rotatable to pivot the second tubular member. 10. A surgical clip applying apparatus for application of surgical clips to body tissue, the apparatus comprising: a housing;a drive assembly at least partially located within the housing;a shaft assembly extending distally from the housing and having a first tubular member and a second tubular member located distally from the first tubular member, the first tubular member defining a first longitudinal axis and being configured to rotate about the first longitudinal axis, the second tubular member supporting a plurality of surgical clips and configured to distally advance each single clip of the plurality of surgical clips, individually, to form the single clip of the plurality of surgical clips upon each single firing of the surgical clip applying apparatus, the first tubular member and the second tubular member being connected through a common pivot axis, the second tubular member defining a second longitudinal axis, the second tubular member being rotatable about the second longitudinal axis, the second tubular member including a geared segment extending proximally from a proximal portion thereof, the drive assembly extending through the first tubular member and partially into the second tubular member;wherein the second tubular member includes a jaw assembly having a pair of juxtaposed jaws, the jaw assembly having a spaced apart condition for entirely receiving a single unformed clip between the pair of jaws, and an approximated condition wherein the pair of jaws form the single clip disposed therebetween, wherein the pair of jaws are approximated in a direction transverse to the second longitudinal axis; anda rack extending along a portion of the longitudinal axis, the rack being located within the first tubular member and configured to reciprocate along the first longitudinal axis, the rack being operatively connected with the geared segment to pivot the second tubular member about the pivot axis. 11. The surgical clip applying apparatus according to claim 10, wherein the second tubular member is configured to pivot about the pivot axis at an angle of up to 90° from the first longitudinal axis. 12. The surgical clip applying apparatus according to claim 10, further comprising a rotation mechanism, the rotation mechanism including a dial and a band located about a proximal portion of the drive assembly, the dial defining an internal passage and an inner surface, the band defining a contoured outer surface configured to receive and transmit a rotational force from the inner surface of the dial to the proximal portion of the drive assembly. 13. The surgical clip applying apparatus according to claim 12, wherein the dial is slidably coupled with the band to permit longitudinal movement of the drive assembly with respect to the dial. 14.
