Abstract

A surgical stapling instrument can comprise an end effector configured to receive a staple cartridge, a shaft including a plurality of staple cartridges positioned therein, and a staple cartridge driver configured to sequentially advance the staple cartridges from the shaft into the end effector. In various embodiments, the staple cartridges can comprise different configurations which can be arranged within the shaft such that they are supplied in a specific predetermined order.

Claims

1. A surgical stapling instrument, comprising:

a handle comprising a trigger;

a shaft extending distally from said handle;

a firing member operably coupled with said trigger such that a firing motion can be transferred from said trigger to said firing member to move said firing member along a firing path;

a first staple cartridge positioned within said shaft, wherein said first staple cartridge comprises;

a first cartridge body comprising a plurality of first apertures positioned in a first longitudinal row; and

a plurality of first staples each comprising at least one first staple leg positioned in a said first aperture, wherein said first staple legs are slidable within said first apertures, and wherein said first staple legs comprise a first length;

a staged second staple cartridge positioned within said shaft behind said first staple cartridge, wherein said second staple cartridge comprises;

a second cartridge body comprising a plurality of second apertures positioned in a second longitudinal row, wherein said second longitudinal row is longitudinally aligned with said first longitudinal row; and

a plurality of second staples each comprising at least one second staple leg positioned in a said second aperture, wherein said second staple legs are longitudinally aligned with said first staple legs, wherein said second staple legs are slidable within said second apertures, and wherein said second staple legs comprise a second length which is different than said first length of said longitudinally aligned first staple legs thereby making said second staple cartridge different than said first staple cartridge;

a first jaw comprising a channel configured to receive a said staple cartridge;

a second jaw comprising an anvil configured to deform said staples; and

a cartridge driver configured to sequentially advance said first and second staple cartridges into said channel from a staging position.

2. The surgical stapling instrument of claim 1, wherein said first staple cartridge is positioned in said staging position, and wherein said second staple cartridge is positioned proximally with respect to said first staple cartridge.

3. The surgical stapling instrument of claim 2, wherein said second length is longer than said first length.

4. The surgical stapling instrument of claim 2, further comprising a third staple cartridge positioned within said shaft, wherein said third staple cartridge comprises:

a third cartridge body comprising a plurality of third apertures; and

a plurality of third staples each comprising at least one third staple leg positioned in a said third aperture, wherein said third staple legs are slidable within said third apertures, and wherein said third staple legs comprise a third length which is different than said first length and said second length.

5. The surgical stapling instrument of claim 1, wherein said first staple cartridge comprises at least one inner row of first staples and at least one outer row of staples comprising a length different than said first length, and wherein said second staple cartridge comprises at least one inner row of second staples and at least one outer row of staples having a length different than said second length.

6. The surgical stapling instrument of claim 1, wherein said first staple cartridge comprises at least one inner row of first staples and at least one outer row of staples comprising a length greater than said first length, and wherein said second staple cartridge comprises at least one inner row of second staples and at least one outer row of staples comprising a length different than said second length.

7. The surgical stapling instrument of claim 1, wherein said first staples are each comprised of wire having a first diameter, and wherein said second staples are each comprised of wire having a second diameter different than said first diameter.

8. A surgical stapling instrument assembly, comprising:

a shaft comprising a removable magazine;

a firing member movable along a firing path;

a first staple cartridge positioned within said magazine, wherein said first staple cartridge comprises;

a first cartridge body comprising a plurality of first apertures positioned in a first longitudinal row; and

a plurality of first staples each comprising a first staple leg positioned in a said first aperture, wherein said first staple legs are slidable within said first apertures, and wherein said first staples each comprise a first height;

a staged second staple cartridge positioned behind said first staple cartridge within said magazine, wherein said second staple cartridge comprises;

a second cartridge body comprising a plurality of second apertures positioned in a second longitudinal row, wherein said second longitudinal row is longitudinally aligned with said first longitudinal row; and

a plurality of second staples each comprising a second staple leg positioned in a said second aperture, wherein said second staple legs are longitudinally aligned with said first staple legs, wherein said second staple legs are slidable within said second apertures, and wherein said second staples comprise a second height which is different than said first height of said longitudinally aligned first staple legs thereby making said second staple cartridge different than said first staple cartridge;

a first jaw comprising a channel configured to receive a said staple cartridge;

a second jaw comprising an anvil configured to deform said staples; and

a cartridge driver configured to sequentially advance said first and second staple cartridges into said channel from a staging position.

9. The surgical stapling instrument assembly of claim 8, wherein said first staple cartridge is positioned in said staging position, and wherein said second staple cartridge is positioned proximally with respect to said first staple cartridge.

10. The surgical stapling instrument assembly of claim 9, wherein said second height is greater than said first height.

11. The surgical stapling instrument assembly of claim 9, further comprising a third staple cartridge positioned within said magazine, wherein said third staple cartridge comprises:

a third cartridge body comprising a plurality of third apertures; and

a plurality of third staples each comprising a third staple leg positioned in a said third aperture, wherein said third staple legs are slidable within said third apertures, and wherein said third staples comprise a third height which is different than said first height and said second height.

12. The surgical stapling instrument assembly of claim 8, wherein said first staple cartridge comprises at least one inner row of first staples and at least one outer row of staples comprising a height different than said first height, and wherein said second staple cartridge comprises at least one inner row of second staples and at least one outer row of staples having a height different than said second height.

13. The surgical stapling instrument assembly of claim 8, wherein said first staple cartridge comprises at least one inner row of first staples and at least one outer row of staples comprising a height greater than said first height, and wherein said second staple cartridge comprises at least one inner row of second staples and at least one outer row of staples comprising a height different than said second height.

14. The surgical stapling instrument assembly of claim 8, wherein said first staples are each comprised of wire having a first diameter, and wherein said second staples are each comprised of wire having a second diameter different than said first diameter.

15. A surgical stapling instrument, comprising:
