Abstract

A staple cartridge assembly is disclosed comprising one or more wire staples and one or more staples formed from a sheet of material.

Claims

1. A staple cartridge assembly, comprising:

a cartridge body, comprising;

a deck comprising a proximal end and a distal end;

a longitudinal slot defined in said deck, wherein said longitudinal slot is configured to receive a firing member;

a first longitudinal row of staple cavities; and

a second longitudinal row of staple cavities;

a sled movable toward said distal end by the firing member during a firing stroke;

a plurality of first staples removably stored in said first longitudinal row of staple cavities, wherein each said first staple is comprised of a bent wire;

a plurality of staple drivers configured to support said first staples, wherein said sled is configured to engage said staple drivers to eject said first staples from said first longitudinal row of staple cavities during the firing stroke; and

a plurality of second staples removably stored in said second longitudinal row of staple cavities, wherein each said second staple is formed from flat stock and comprises an integrally-formed driver, and wherein said sled is configured to directly engage said integrally-formed drivers of said second staples and eject said second staples from said second longitudinal row of staple cavities during the firing stroke.

2. The staple cartridge assembly of claim 1, wherein said first longitudinal row of staple cavities is adjacent said longitudinal slot, and wherein said first longitudinal row of staple cavities is intermediate said longitudinal slot and said second longitudinal row of staple cavities.

3. The staple cartridge assembly of claim 1, wherein said second longitudinal row of staple cavities is adjacent said longitudinal slot, and wherein said second longitudinal row of staple cavities is intermediate said longitudinal slot and said first longitudinal row of staple cavities.

4. The staple cartridge assembly of claim 1, wherein said cartridge body further comprises a third longitudinal row of staple cavities, wherein said staple cartridge assembly further comprises a plurality of third staples removably stored in said third longitudinal row of staple cavities, and wherein each said third staple is comprised of a bent wire.

5. The staple cartridge assembly of claim 4, wherein said third longitudinal row of staple cavities is adjacent said first longitudinal row of staple cavities, wherein said staple drivers are configured to support said third staples, and wherein said sled is configured to engage said staple drivers to eject said third staples from said third longitudinal row of staple cavities during the firing stroke.

6. The staple cartridge assembly of claim 4, further comprising a plurality of staple drivers configured to support said third staples and be engaged by said sled to eject said third staples from said third longitudinal row of staple cavities during the firing stroke.

7. The staple cartridge assembly of claim 1, wherein said cartridge body further comprises a third longitudinal row of staple cavities, wherein said staple cartridge assembly further comprises a plurality of third staples removably stored in said third longitudinal row of staple cavities, wherein each said third staple is formed from flat stock and comprises an integrally-formed driver, and wherein said sled is configured to directly engage said integrally-formed drivers of said third staples and eject said third staples from said third longitudinal row of staple cavities during the firing stroke.

8. The staple cartridge assembly of claim 7, wherein said third longitudinal row of staple cavities is adjacent said longitudinal slot, wherein said second longitudinal row of staple cavities is adjacent said third longitudinal row of staple cavities, and wherein said second longitudinal row of staple cavities is intermediate said first longitudinal row of staple cavities and said third longitudinal row of staple cavities.

9. A staple cartridge assembly, comprising:

a cutting member;

a cartridge body, comprising;

a deck comprising a proximal end and a distal end;

a longitudinal slot defined in said deck, wherein said longitudinal slot is configured to receive said cutting member;

a first longitudinal row of staple cavities; and

a second longitudinal row of staple cavities;

a sled movable toward said distal end by said cutting member during a firing stroke;

a plurality of first staples removably stored in said first longitudinal row of staple cavities, wherein each said first staple is comprised of a bent wire;

a plurality of staple drivers configured to support said first staples, wherein said sled is configured to engage said staple drivers to eject said first staples from said first longitudinal row of staple cavities during said firing stroke; and

a plurality of second staples removably stored in said second longitudinal row of staple cavities, wherein said second staples are stamped from one or more metal sheets, and wherein said sled is configured to directly engage said second staples and eject said second staples from said second longitudinal row of staple cavities during said firing stroke.

10. The staple cartridge assembly of claim 9, wherein said first longitudinal row of staple cavities is adjacent said longitudinal slot, and wherein said first longitudinal row of staple cavities is intermediate said longitudinal slot and said second longitudinal row of staple cavities.

11. The staple cartridge assembly of claim 9, wherein said second longitudinal row of staple cavities is adjacent said longitudinal slot, and wherein said second longitudinal row of staple cavities is intermediate said longitudinal slot and said first longitudinal row of staple cavities.

12. The staple cartridge assembly of claim 9, wherein said cartridge body further comprises a third longitudinal row of staple cavities, wherein said staple cartridge assembly further comprises a plurality of third staples removably stored in said third longitudinal row of staple cavities, and wherein each said third staple is comprised of a bent wire.

13. The staple cartridge assembly of claim 12, wherein said third longitudinal row of staple cavities is adjacent said first longitudinal row of staple cavities, wherein said staple drivers are configured to support said third staples, and wherein said sled is configured to engage said staple drivers to eject said third staples from said third longitudinal row of staple cavities during said firing stroke.

14. The staple cartridge assembly of claim 12, further comprising a plurality of staple drivers configured to support said third staples and be engaged by said sled to eject said third staples from said third longitudinal row of staple cavities during said firing stroke.

15. The staple cartridge assembly of claim 9, wherein said cartridge body further comprises a third longitudinal row of staple cavities, wherein said staple cartridge assembly further comprises a plurality of third staples removably stored in said third longitudinal row of staple cavities, wherein said third staples are formed from one or more metal sheets, and wherein said sled is configured to directly engage said third staples and eject said third staples from said third longitudinal row of staple cavities during said firing stroke.

16. The staple cartridge assembly of claim 15, wherein said third longitudinal row of staple cavities is adjacent said longitudinal slot, wherein said second longitudinal row of staple cavities is adjacent said third longitudinal row of staple cavities, and wherein said second longitudinal row of staple cavities is intermediate said first longitudinal row of staple cavities and said third longitudinal row of staple cavities.

17. A staple cartridge assembly, comprising:

a cartridge body, comprising;

a deck comprising a proximal end and a distal end;

a longitudinal slot defined in said deck, wherein said longitudinal slot is configured to receive a firing member; and

a plurality of staple cavities;

a sled movable toward said distal end by the firing member during a firing stroke;

a plurality of first staples removably stored in said staple cavities, wherein each said first staple is comprised of a bent wire;

a plurality of staple drivers, wherein said sled is configured to engage said staple drivers to eject said first staples from said staple cavities during the firing stroke; and
