A loading unit for a surgical stapling device has a cartridge assembly and an anvil assembly, the cartridge assembly including a channel and a staple cartridge having a plurality of surgical staples therein. An axial drive assembly has a clamping member, the clamping member having an upper flange for engaging the anvil assembly, and a lower flange for engaging the channel. The axial drive assembly is movable through the staple cartridge to drive the staples out of the staple cartridge and against the anvil assembly. Mechanical features are defined in the channel for indicating an end of stroke for the axial drive assembly, the mechanical features having a first pattern and a second pattern.
1. A loading unit for a surgical stapling device, comprising: a cartridge assembly including: a channel;an axial drive assembly having a clamping member, the clamping member having a flange configured to engage the channel; andat least one mechanical feature defined in the channel for indicating an
1. A loading unit for a surgical stapling device, comprising: a cartridge assembly including: a channel;an axial drive assembly having a clamping member, the clamping member having a flange configured to engage the channel; andat least one mechanical feature defined in the channel for indicating an end of stroke upon engagement by the axial drive assembly, the at least one mechanical feature selected from the group consisting of a bump, a depression, a recess, and combinations thereof;a motor configured to move the axial drive assembly; anda controller coupled to the motor and configured to determine the end of stroke based on a change in torque of the motor in response to the clamping member engaging the at least one mechanical feature. 2. The loading unit according to claim 1, wherein the at least one mechanical feature includes a first mechanical feature and at least a second mechanical feature, the first and second mechanical features having different sizes. 3. The loading unit according to claim 1, wherein the at least one mechanical feature includes a first mechanical feature and at least a second mechanical feature, the first and second mechanical features having the same sizes. 4. The loading unit according to claim 1, wherein the at least one mechanical feature includes a first mechanical feature and at least a second mechanical feature, the first and second mechanical features are the same type. 5. The loading unit according to claim 1, wherein the at least one mechanical feature includes a first mechanical feature and at least a second mechanical feature, the first and second mechanical features are of different type. 6. The loading unit according to claim 1, wherein a distal end of the channel forms the end of stroke. 7. The loading unit according to claim 1, further comprising a first plurality of mechanical features disposed in a first pattern and a second plurality of mechanical features disposed in a second pattern, wherein the first plurality of mechanical features is closer to a distal end of the channel than the second plurality of mechanical features. 8. The loading unit according to claim 1, further comprising a light sensor configured to detect the at least one mechanical feature. 9. The loading unit according to claim 1, further comprising an anvil assembly coupled to the cartridge assembly, wherein the clamping member is configured to engage the anvil assembly and the channel. 10. The loading unit according to claim 1, wherein the cartridge assembly further includes a staple cartridge having a plurality of surgical staples therein, the axial drive assembly being movable through the staple cartridge to drive the staples out of the staple cartridge. 11. A loading unit for a surgical stapling device, comprising: a cartridge assembly including: a channel;an axial drive assembly having a clamping member, the clamping member having a flange configured to engage the channel; andat least one mechanical feature defined in the channel for indicating an end of stroke upon engagement by the axial drive assembly;a motor configured to move the axial drive assembly; anda controller coupled to the motor and configured to determine the end of stroke based on a change in torque of the motor in response to the clamping member engaging the at least one mechanical feature. 12. The loading unit according to claim 11, wherein the at least one mechanical feature includes a first mechanical feature and at least a second mechanical feature, the first and second mechanical features having different sizes. 13. The loading unit according to claim 11, wherein the at least one mechanical feature includes a first mechanical feature and at least a second mechanical feature, the first and second mechanical features having the same sizes. 14. The loading unit according to claim 11, wherein a distal end of the channel forms the end of stroke. 15. The loading unit according to claim 11, further comprising a first plurality of mechanical features disposed in a first pattern and a second plurality of mechanical features disposed in a second pattern, wherein the first plurality of mechanical features is closer to a distal end of the channel than the second plurality of mechanical features. 16. The loading unit according to claim 11, further comprising a light sensor configured to detect the at least one mechanical feature. 17. The loading unit according to claim 11, further comprising an anvil assembly coupled to the cartridge assembly, wherein the clamping member is configured to engage the anvil assembly and the channel. 18. The loading unit according to claim 11, wherein the cartridge assembly further includes a staple cartridge having a plurality of surgical staples therein, the axial drive assembly being movable through the staple cartridge to drive the staples out of the staple cartridge.
