CLAIMS

1. A surgical cartridge assembly, comprising:

a proximal end;

a distal end;

an elongate channel, comprising:

a base; and

at least one opening within the base;

a slot configured to receive a cutting member;

a cartridge body configured to be removably received within the elongate channel; and

at least one lockout tab extending from the proximal end of the cartridge body, wherein the at least one lockout tab is configured to cover the at least one opening when the cartridge body is received within the elongate channel, and wherein the at least one lockout tab disables a lockout mechanism to allow the cutting member to advance distally through the slot.

2. The surgical cartridge assembly of Claim 1 , wherein the elongate channel further comprises at least one ledge on the base positioned distal to the at least one opening.

3. The surgical cartridge assembly of Claim 2, wherein the at least one lockout tab is configured to cover the at least one ledge when the cartridge body is received within the elongate channel.

4. The surgical cartridge assembly of Claim 1 , wherein the at least one lockout tab comprises at least one lockout pad configured to be received within the at least one opening when the cartridge body is received within the elongate channel.

5. The surgical cartridge assembly of Claim 1 , wherein a portion of the cutting member is configured to be received within the at least one opening of the elongate channel in the absence of a cartridge body.

6. The surgical cartridge assembly of Claim 1 , wherein the surgical cartridge assembly comprises a staple cartridge.

7. The surgical cartridge assembly of Claim 1 , wherein the surgical cartridge assembly comprises a RF cartridge.

8. An end effector for a surgical instrument, the end effector comprising:

a proximal end;

a distal end;

a first jaw;

a second jaw comprising an elongate channel including a base, wherein the base of the elongate channel comprises:

a first opening; and

a second opening; and

a surgical cartridge configured to be removably received within the elongate channel, the surgical cartridge comprising:

a cartridge body;

a slot configured to receive a cutting member;

a first tab extending from the proximal end of the cartridge body on a first side of the slot, wherein the first tab is configured to cover the first opening and the first ledge when the surgical cartridge is received within the elongate channel; and

a second tab extending from the proximal end of the cartridge body on a second side of the slot, wherein the second tab is configured to cover the second opening and the second ledge when the surgical cartridge is received within the elongate channel, and wherein the first tab and the second tab disable a lockout mechanism to allow a cutting member to advance distally through the slot.

9. The end effector of Claim 8, wherein the elongate channel further comprises a first ledge and a second ledge, wherein the first ledge is positioned on the base distal to the first opening, and wherein the second ledge is positioned on the base distal to the second opening.

10. The end effector of Claim 9, wherein the first tab is configured to cover the first ledge when the surgical cartridge is received within the elongate channel, and the second tab is configured to cover the second ledge when the surgical cartridge is received within the elongate channel.

1 1 . The end effector of Claim 8, wherein the first tab comprises a first pad configured to be received within the first opening when the surgical cartridge is received within the elongate channel.

12. The end effector of Claim 8, wherein a first portion of the cutting member is configured to be received within the first opening of the elongate channel in the absence of a surgical cartridge, and wherein a second portion of the cutting member is configured to be received within the second opening of the elongate channel in the absence of a surgical cartridge.

13. The end effector of Claim 8, wherein the surgical cartridge comprises a staple cartridge.

14. The end effector of Claim 8, wherein the surgical cartridge comprises a RF cartridge.

15. A surgical cartridge assembly, comprising:

a proximal end;

a distal end;

an elongate channel, comprising:

a base;

a first opening; and

a second opening;

a surgical cartridge configured to be removably received within the elongate channel, the surgical cartridge comprising:

a cartridge body;

a longitudinal slot configured to receive a cutting member;

a first lockout projection extending proximally from the proximal end of the cartridge body on a first side of the slot, wherein the first lockout projection is configured to cover the first opening when the surgical cartridge is received within the elongate channel; and a second lockout projection extending proximally from the proximal end of the cartridge body on a second side of the slot, wherein the second lockout projection is configured to cover the second opening when the surgical cartridge is received within the elongate channel, and wherein the first lockout projection and the second lockout projection disable a lockout mechanism to allow a cutting member to advance distally through the slot.

16. The surgical cartridge assembly of Claim 15, wherein the elongate channel further comprises a first ledge on the base positioned distal to the first opening and a second ledge on the base positioned distal to the second opening.

17. The surgical cartridge assembly of Claim 16, wherein the first lockout projection is configured to cover the first ledge when the surgical cartridge is received within the elongate channel, and the second lockout projection is configured to cover the second ledge when the surgical cartridge is received within the elongate channel.

18. The surgical cartridge assembly of Claim 15, wherein the first lockout projection comprises a first lockout pad configured to be received within the first opening when the surgical cartridge is received within the elongate channel.

19. The surgical cartridge assembly of Claim 15, wherein the surgical cartridge comprises a staple cartridge.

20. The surgical cartridge assembly of Claim 15, wherein the surgical cartridge comprises a RF cartridge.
