A loading unit is provided. The loading unit includes a housing defining a longitudinal axis, a mounting support pivotally connected to the housing and including a tool assembly operably connected thereto, a curved guide member extending between the housing and the support member, and a drive member extending through the curved guide member for actuating the tool assembly when the mounting support is articulated relative to the housing.
1. A loading unit comprising: a housing defining a longitudinal axis;a mounting support pivotally connected to the housing and including a tool assembly operably connected thereto, the mounting support movable between a first position in alignment with the longitudinal axis and a second position art
1. A loading unit comprising: a housing defining a longitudinal axis;a mounting support pivotally connected to the housing and including a tool assembly operably connected thereto, the mounting support movable between a first position in alignment with the longitudinal axis and a second position articulated relative to the longitudinal axis;a guide member extending between the housing and the mounting support, the guide member defining a curved longitudinal slot when the mounting support is in the first position; anda drive member extending through the curved longitudinal slot of the guide member for actuating the tool assembly when the mounting support is in the second position. 2. The loading unit of claim 1, wherein the mounting support is pivotally connected to the housing by a pair of connecting elements. 3. The loading unit of claim 1, wherein a pivot point between the mounting support and the housing is axial off-set from the longitudinal axis. 4. The loading unit of claim 1, wherein the tool assembly includes an anvil and a cartridge assembly. 5. The loading unit of claim 1, wherein the drive member includes a substantially flattened member. 6. The loading unit of claim 1, wherein the guide member is slidably movable relative to the housing as the mounting member pivots between the first and second positions. 7. The loading unit of claim 1, wherein the guide member includes first and second proximal tabs and the housing includes first and second slots, the first and second tabs being slidably movable within the first and second slots. 8. The loading unit of claim 1, wherein the guide member includes first and second guide halves. 9. The loading unit of claim 8, wherein each of the first and second guide halves define a channel which together form the curved longitudinal slot. 10. A surgical stapler comprising: a handle assembly;an elongate body portion extending from the handle assembly;a housing defining a longitudinal axis and being disposed adjacent the distal end of the elongate body portion;a mounting support pivotally connected to the housing and including a tool assembly operably connected thereto;a curved guide member extending between the housing and the mounting support, wherein the curved guide member includes upper and lower guide halves each having a proximal tab that slidably engages the housing; anda drive member extending through the curved guide member for actuating the tool assembly when the mounting support is articulated relative to the housing. 11. The surgical stapler of claim 10, wherein the mounting support is pivotally connected to the housing by a pair of connecting elements. 12. The surgical stapler of claim 10, wherein a pivot point between the mounting support and the housing is axial off-set from the longitudinal axis. 13. The surgical stapler of claim 10, wherein the tool assembly includes an anvil and a cartridge assembly. 14. The surgical stapler of claim 10, wherein the drive member includes a substantially flattened member. 15. The surgical stapler of claim 10, wherein each of the first and second guide halves of the curved guide member defines a curved channel which together form a curved longitudinal slot for receipt of the drive member. 16. The surgical stapler of claim 10, wherein the curved guide member is slidably movable as the mounting support pivots. 17. A surgical stapler, comprising: a handle assembly;an elongate body portion extending from the handle assembly;a housing defining a longitudinal axis and a slot, the housing being disposed adjacent the distal end of the elongate body portion;a mounting support pivotally connected to the housing and including a tool assembly operably connected thereto;a curved guide member extending between the housing and the mounting support, wherein the curved guide member includes a proximal tab slidably received within the slot in the housing such that the guide member is slidably movable as the mounting support pivots; anda drive member extending through the curved guide member for actuating the tool assembly when the mounting support is articulated relative to the housing. 18. The surgical stapler of claim 17, wherein the curved guide member has a distal tab that is connected to the mounting support. 19. A surgical instrument comprising: an elongate body defining a longitudinal axis;a mounting support pivotally connected to the elongate body, the mounting support movable between a first position in alignment with the longitudinal axis and a second position articulated relative to the longitudinal axis,;a guide member extending between the elongate body and the mounting support, the guide member defining a curved longitudinal slot having a fixed radius of curvature when the mounting support is in the first position and when the mounting support is in the second position; anda drive member extending through the curved longitudinal slot of the guide member.
