A surgical stapling apparatus for progressively stapling and forming an incision in body tissue is provided. The apparatus includes a body portion and a tool assembly supported on the body portion. The apparatus further includes an input cam member slidable within the body portion, a drum member rotatably supported within the body portion, and an output cam member slidable within the body portion. The drum member is coupled to the input cam member such that linear movement of the input cam member effects rotatable movement of the drum member. The output cam member is coupled to the drum member such that rotatable movement of the drum member effects linear movement of the output cam member. Linear movement of the input cam member effects movement of an anvil in relation to a cartridge between unclamped and clamped positions.

1. A surgical stapling apparatus comprising: a body portion defining a longitudinal axis;a tool assembly supported on the body portion, the tool assembly including an anvil and a cartridge;an input cam member slidable within the body portion;a drum member rotatably supported within the body portion

1. A surgical stapling apparatus comprising: a body portion defining a longitudinal axis;a tool assembly supported on the body portion, the tool assembly including an anvil and a cartridge;an input cam member slidable within the body portion;a drum member rotatably supported within the body portion about the longitudinal axis, the drum member being coupled to the input cam member such that linear movement of the input cam member causes rotatable movement of the drum member; andan output cam member slidable within the body portion, the output cam member being coupled to the drum member such that rotatable movement of the drum member causes linear movement of the output cam member, wherein the anvil is coupled to the output cam member such that the linear movement of the input cam member causes movement of the anvil in relation to the cartridge between unclamped and clamped positions. 2. The apparatus of claim 1, wherein the drum member includes a first post and a second post and the input cam member and output cam member each define a slot, the first post being slidably received in the slot of the input cam member and the second post being slidably received within the slot of the output cam member. 3. The apparatus of claim 2, wherein the slot of the input cam member includes a helical portion and a linear portion and the slot in the output cam member is helical. 4. The apparatus of claim 3, wherein the advancement of the input cam member causes the first post to traverse the helical portion of the slot in the input cam member to rotate the drum member and rotation of the drum member causes the second post to traverse the slot of the output cam member to cause linear movement of the output cam member. 5. The apparatus of claim 4, wherein receipt of the first post within the linear portion of the slot in the input cam member permits linear movement of the input cam member without causing rotatable movement of the drum member. 6. The apparatus of claim 1, further including a pusher driver coupled to the input cam member, wherein the pusher driver defines dwell slots and the input cam member defines tabs, the tabs being slidably received within the dwell slots to permit linear movement of the input cam member relative to the pusher driver, wherein linear advancement of the pusher driver causes corresponding movement of the input cam member after the tabs are advanced to a distal end of the dwell slots. 7. The apparatus of claim 6, further including a knife driver coupled to the input cam member, wherein the knife driver defining dwell slots, the tabs of the input cam member being slidably received within the dwell slots of the knife driver to permit linear movement of the input cam member relative to the knife driver, wherein linear advancement of the knife driver corresponds to movement of the input cam member after the tabs are advanced to a distal end of the dwell slots of the knife driver. 8. The apparatus of claim 7, wherein the distal end of the dwell slots of the knife driver are spaced distally from the distal end of the dwell slots of the pusher driver such that the input cam member causes advancement of the knife driver subsequent to advancing the pusher driver. 9. The apparatus of claim 8, wherein advancement of the pusher driver staples tissue. 10. The apparatus of claim 8, wherein advancement of the knife driver cuts tissue. 11. The apparatus of claim 8, further including a staple supply assembly supported within the tool assembly, the staple supply assembly including a pair of pressure plates each including a plurality of extensions that engage a proximal staple in a plurality of rows of staples. 12. The apparatus of claim 11, wherein the pressure plates are biased in a distal direction by a spring. 13. The apparatus of claim 12, wherein the spring is connected to each of the pressure plates by a spring clip. 14. The apparatus of claim 11, wherein each of the pair of pressures plates includes three extensions.
