The present invention includes a surgical stapler having a staple cartridge, an anvil, and a cutting member having a cutting surface, wherein the cutting member is relatively movable with respect to the anvil and the staple cartridge. In at least one embodiment, one of the anvil and the staple cartridge defines a slot which is configured to receive at least a portion of the cutting member and guide the cutting member as it is moved relative to the anvil and the staple cartridge. In these embodiments, the slot can define a path having linear and/or curved portions. In various embodiments, the path can include a curved portion having a first portion that extends away from the shaft axis and a second portion that extends toward the axis. In one embodiment, the path can include a curved portion defined by an arc corresponding to an angle greater than 90 degrees.
1. A surgical stapler, comprising: a handle portion;a shaft extending from said handle portion, said shaft including a proximal portion and a distal portion, wherein said distal portion defines an axis; andan end-effector extending from said distal portion, said end-effector comprising:a channel con
1. A surgical stapler, comprising: a handle portion;a shaft extending from said handle portion, said shaft including a proximal portion and a distal portion, wherein said distal portion defines an axis; andan end-effector extending from said distal portion, said end-effector comprising:a channel configured for receiving a staple cartridge, the staple cartridge configured to removably store staples therein;an anvil configured to deform said staples, wherein at least one of said anvil and the staple cartridge defines a slot; anda cutting member having a cutting surface, wherein said cutting member is relatively movable with respect to said anvil and the staple cartridge, wherein said slot is configured to receive at least a portion of said cutting member and define a path for said cutting member as it is moved relative to said anvil and the staple cartridge, wherein said path includes a linear portion, and a curved portion defined by at least one radius of curvature, and wherein said linear portion defines an axis that is not parallel to or collinear with said shaft axis. 2. The surgical stapler of claim 1, wherein said linear portion has a proximal end and a distal end, wherein said proximal end is positioned closer to said shaft axis than said distal end, wherein said curved portion includes a proximal end and a distal end, and wherein said distal end is positioned along said shaft axis. 3. The surgical stapler of claim 2, wherein said shaft axis is defined by a centerline of said distal portion of said shaft. 4. The surgical stapler of claim 1, wherein said curved portion includes a proximal portion that extends away from said shaft axis and a distal portion that extends toward said shaft axis. 5. The surgical stapler of claim 1, further comprising said staple cartridge, wherein said staple cartridge includes a linear portion corresponding to said linear portion of said path and a curved portion corresponding to said curved portion of said path. 6. The surgical stapler of claim 5, wherein said staple cartridge includes cavities for storing said staples therein, and wherein said cavities are positioned within said curved portion of said staple cartridge and not within said linear portion. 7. The surgical stapler of claim 1, wherein said staple cartridge channel includes a linear portion corresponding to said linear portion of said path and a curved portion corresponding to said curved portion of said path. 8. The surgical stapler of claim 1, wherein said anvil includes a linear portion corresponding to said linear portion of said path and a curved portion corresponding to said curved portion of said path. 9. The surgical stapler of claim 1, wherein said curved portion defines an arc corresponding to an angle at least 90 degrees. 10. The surgical stapler of claim 1, wherein said curved portion defines an arc corresponding to an angle at least 30 degrees. 11. A method for processing an instrument for surgery, comprising: obtaining the surgical stapler of claim 1;sterilizing said surgical stapler; andstoring said surgical stapler in a sterile container. 12. The surgical stapler of claim 1, wherein said linear portion has a proximal end and a distal end, wherein said proximal end is positioned closer to said shaft axis than said distal end, wherein said curved portion includes a proximal end and a distal end, and wherein said distal end is positioned beyond said shaft axis. 13. The surgical stapler of claim 12, wherein said shaft axis is defined by a centerline of said distal portion of said shaft. 14. A surgical stapler, comprising: a handle portion;a shaft extending from said handle portion, said shaft including a proximal portion and a distal portion, wherein said distal portion defines an axis; andan end-effector extending from said distal portion, said end-effector comprising: a channel configured for receiving a staple cartridge, the staple cartridge configured to removably store staples therein;an anvil configured to deform said staples, wherein at least one of said anvil and the staple cartridge defines a slot; anda cutting member having a cutting surface, wherein said cutting member is relatively movable with respect to said anvil and the staple cartridge, wherein said slot is configured to receive at least a portion of said cutting member and define a path for said cutting member as it is moved relative to said anvil and the staple cartridge, wherein said path includes a linear portion, and a curved portion defined by at least one radius of curvature, wherein said linear portion has a proximal end and a distal end, wherein said proximal end is positioned closer to said axis than said distal end, wherein said curved portion includes a first portion and a second portion, wherein said first portion is closer to said shaft than said second portion, and wherein said second portion is closer to said axis than said first portion. 15. The surgical stapler of claim 14, wherein said second portion of said curved portion includes a distal end, and wherein said curved portion distal end is positioned along said axis. 16. The surgical stapler of claim 15, wherein said axis is defined by a centerline of said distal portion of said shaft. 17. The surgical stapler of claim 14, wherein said first portion of said curved portion extends away from said axis and said second portion extends toward said axis. 18. The surgical stapler of claim 14, further comprising said staple cartridge, wherein said staple cartridge includes a linear portion corresponding to said linear portion of said path and a curved portion corresponding to said curved portion of said path, and wherein said staple cartridge includes cavities for storing said staples therein, and wherein said cavities are positioned within said curved portion of said staple cartridge and not within said linear portion. 19. The surgical stapler of claim 14, wherein said second portion of said curved portion includes a distal end, and wherein said curved portion distal end is positioned beyond said axis. 20. The surgical stapler of claim 19, wherein said axis is defined by a centerline of said distal portion of said shaft.
