An assembly for use with a surgical instrument system is disclosed which comprises a cartridge body removably positionable in a channel. The system further comprises staple cavities and a longitudinal slot defined in the cartridge body, staples positioned in the staple cavities, and pushers configured to eject the staples from the staple cavities. The system further comprises rotary drivers couplable to the pushers. The system further comprises a rotatable shaft comprising a threaded portion rotatable by a motor and, in addition, a firing member comprising a threaded aperture engaged with the rotatable shaft which is configured to displace the firing member longitudinally when the shaft is rotated. The firing member comprises a first ramp positioned on a first side of the slot configured to actuate a first row of pushers and a second ramp configured to actuate a second row of pushers disposed laterally with respect to the first ramp.
1. An end effector for use with a surgical instrument system, said end effector comprising: a cartridge channel;a longitudinal axis;a staple cartridge removably positioned in said cartridge channel, comprising: a cartridge body comprising a plurality of staple cavities, wherein said staple cavities
1. An end effector for use with a surgical instrument system, said end effector comprising: a cartridge channel;a longitudinal axis;a staple cartridge removably positioned in said cartridge channel, comprising: a cartridge body comprising a plurality of staple cavities, wherein said staple cavities are arranged in six longitudinal rows;a plurality of staples, wherein said staples are removably positioned in said staple cavities;a plurality of pushers, wherein said pushers are configured to eject said staples from said staple cavities;a plurality of rotary drivers couplable to said plurality of pushers; anda longitudinal slot, wherein three of said six longitudinal rows of staple cavities are positioned on a first side of said longitudinal slot, and wherein the other three of said six longitudinal rows of staple cavities are positioned on a second side of said longitudinal slot;a rotatable shaft comprising a threaded portion, wherein said rotatable shaft is rotatable by a motor; anda translatable sled, comprising: a threaded aperture threadably engaged with said threaded portion, wherein said shaft is configured to displace said sled longitudinally when said shaft is rotated;a knife aligned with said longitudinal slot;a first ramp positioned on said first side of said longitudinal slot, wherein said first ramp is configured to actuate a first group of said rotary drivers; anda second ramp configured to actuate a second group of said rotary drivers, wherein said second ramp is aligned laterally with said first ramp. 2. The end effector of claim 1, further comprising said motor. 3. The end effector of claim 1, further comprising: a housing, wherein said motor is positioned in said housing; andan elongate shaft extending from said housing, wherein said elongate shaft comprises: a proximal end;a distal end; andan articulation joint, wherein said staple cartridge is rotatable about said articulation joint, wherein said threaded portion extends distally with respect to said articulation joint, and wherein the rotational motion of said rotatable shaft is converted to translational motion of said sled distally with respect to said articulation joint. 4. The end effector of claim 1, wherein at least one of said rotary drivers comprises an arcuate ramp portion. 5. The end effector of claim 1, wherein at least one of said rotary drivers is rotatably supported within said cartridge body. 6. The end effector of claim 1, wherein said first group of said rotary drivers are positioned on said first side of said longitudinal slot, and wherein said second group of said rotary drivers are positioned on said second side of said longitudinal slot. 7. An assembly for use with a surgical instrument system, said assembly comprising: a cartridge channel;a longitudinal axis;a cartridge body removably positionable in said cartridge channel, wherein said cartridge body comprises a plurality of staple cavities, and wherein said staple cavities are arranged in an array consisting of six longitudinal rows;a plurality of staples, wherein said staples are removably positioned in said staple cavities;a plurality of pushers, wherein said pushers are configured to eject said staples from said staple cavities, and wherein said pushers are arranged in longitudinal rows;a plurality of rotary drivers couplable to said plurality of pushers;a longitudinal slot, wherein three of said six longitudinal rows of staple cavities are positioned on a first side of said longitudinal slot, and wherein the other three of said six longitudinal rows of staple cavities are positioned on a second side of said longitudinal slot;a rotatable shaft comprising a threaded portion, wherein said rotatable shaft is rotatable by a motor; anda firing member, comprising: a threaded aperture threadably engaged with said threaded portion, wherein said shaft is configured to displace said firing member longitudinally when said shaft is rotated;a knife aligned with said longitudinal slot;a first ramp positioned on said first side of said longitudinal slot, wherein said first ramp is configured to actuate a first row of said rotary drivers; anda second ramp configured to actuate a second row of said rotary drivers, wherein said second ramp is disposed laterally with respect to said first ramp. 8. The assembly of claim 7, further comprising said motor. 9. The assembly of claim 7, further comprising: a housing, wherein said motor is positioned in said housing; andan elongate shaft extending from said housing, wherein said elongate shaft comprises: a proximal end;a distal end; andan articulation joint, wherein said cartridge channel is rotatable about said articulation joint, wherein said threaded portion extends distally with respect to said articulation joint, and wherein the rotational motion of said rotatable shaft is converted to translational motion of said firing member distally with respect to said articulation joint. 10. A surgical instrument system, comprising: a cartridge channel;a cartridge body removably positionable in said cartridge channel, wherein said cartridge body comprises a plurality of staple cavities, and wherein said staple cavities are arranged in an array consisting of six longitudinal rows;a plurality of staples, wherein said staples are removably positioned in said staple cavities;a plurality of pushers, wherein said drivers are configured to eject said staples from said staple cavities, and wherein said pushers are arranged in longitudinal rows;a plurality of rotary drivers couplable to said plurality of pushers;a longitudinal knife slot, wherein three of said six longitudinal rows of staple cavities are positioned on a first side of said longitudinal knife slot, and wherein the other three of said six longitudinal rows of staple cavities are positioned on a second side of said longitudinal knife slot;a housing;an electric motor positioned within said housing;a rotatable shaft comprising a threaded portion, wherein said rotatable shaft is rotatable by said electric motor; anda firing member, comprising: a threaded aperture threadably engaged with said threaded portion, wherein said shaft is configured to displace said firing member longitudinally when said shaft is rotated;a knife configured to travel through said longitudinal knife slot;a first ramp positioned on said first side of said longitudinal knife slot, wherein said first ramp is configured to actuate a first longitudinal row of said rotary drivers; anda second ramp configured to actuate a second longitudinal row of said rotary drivers, wherein said second ramp is aligned with said first ramp. 11.
