Abstract

A staple cartridge for use with a surgical stapler can comprise a cartridge deck and a plurality of staples at least partially positioned within the cartridge deck. In various embodiments, the staples can be supported by a support jaw of the surgical stapler and can comprise legs which can extend upwardly through apertures defined in the cartridge deck. In use, the cartridge deck can be pushed downwardly relative to the staples into a well defined in the support jaw.

Claims

1. An end effector of a surgical stapling instrument configured to support a staple cartridge, the staple cartridge including a deck and a plurality of staples, said end effector comprising:

a support jaw, comprising;

a frame;

a plurality of stationary drivers extending from said frame, wherein each said stationary driver is configured to support a staple; and

a well defined intermediate said stationary drivers, wherein said well is configured to receive the deck of the staple cartridge; and

an anvil jaw movably attached to said support jaw, wherein said anvil jaw is movable between an unfired position and a fired position, said anvil jaw comprising;

a tissue-contacting surface; and

a plurality of staple pockets configured to deform the staples.

2. The end effector of claim 1, wherein said stationary drivers are integral with said frame.

3. The end effector of claim 2, wherein said frame and said stationary drivers are comprised of a unitary piece of metal.

4. The end effector of claim 1, wherein each said stationary driver comprises a groove configured to receive a base of a staple therein.

5. The end effector of claim 4, wherein said support jaw further comprises a longitudinal slot configured to receive at least a portion of a cutting member, and wherein said grooves of said stationary drivers are parallel to said longitudinal slot.

6. The end effector of claim 4, wherein said support jaw further comprises a longitudinal slot configured to receive at least a portion of a cutting member, and wherein said grooves are not parallel to said longitudinal slot.

7. The end effector of claim 1, wherein each said stationary driver comprises an outer perimeter, and wherein said outer perimeter is tapered.

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

a staple cartridge, comprising;

a deck comprising a top surface; and

a plurality of staples at least partially extending through said deck, wherein said deck is slidable relative to said staples between an unfired position and a fired position;

a support jaw, comprising;

a frame;

a plurality of stationary drivers extending from said frame, wherein each said stationary driver is configured to support a said staple, and wherein said top surface of said deck is positioned above said stationary drivers when said deck is in said unfired position; and

a well defined intermediate said stationary drivers, wherein said well is configured to receive said deck when said deck is in said fired position; and

an anvil jaw movable movably attached to said support jaw, wherein said anvil jaw is movable between an unfired position and a fired position, said anvil comprising;

a tissue-contacting surface; and

a plurality of staple pockets configured to deform the staples.

9. The end effector of claim 8, wherein said anvil jaw is configured to drive said deck between its unfired position and its fired position as said anvil jaw is moved between its unfired position and its fired position.

10. The end effector of claim 8, wherein said stationary drivers are integral with said frame.

11. The end effector of claim 10, wherein said frame and said stationary drivers are comprised of a unitary piece of metal.

12. The end effector of claim 8, wherein each said stationary driver comprises a groove configured to receive a base of a said staple therein.

13. The end effector of claim 12, wherein said support jaw further comprises a longitudinal slot configured to receive at least a portion of a cutting member, and wherein said grooves are parallel to said longitudinal slot.

14. The end effector of claim 12, wherein said support jaw further comprises a longitudinal slot configured to receive at least a portion of a cutting member, and wherein said grooves are not parallel to said longitudinal slot.

15. The end effector of claim 8, wherein each said stationary driver comprises an outer perimeter, and wherein said outer perimeter is tapered.

16. The end effector of claim 8, wherein said deck further comprises a plurality of apertures configured to receive said stationary drivers when said deck is moved into said fired position.

17. The end effector of claim 16, wherein said stationary drivers are configured to engage the sidewalls of said apertures in a press-fit manner.

18. An end effector of a surgical stapling instrument configured to support a staple cartridge, the staple cartridge including a deck and a plurality of staples, wherein the deck is slidable relative to the staples between an unfired position and a fired position, said end effector comprising:

a support jaw, comprising;

a frame;

a plurality of stationary drivers extending from said frame, wherein each said stationary driver is configured to support a staple; and

a depression defined intermediate said stationary drivers, wherein said depression is configured to receive the deck of the staple cartridge when the deck is the fired position; and

an anvil jaw movably attached to said support jaw, wherein said anvil jaw is movable between an unfired position and a fired position, said anvil jaw comprising;

a tissue compression surface; and

a plurality of staple pockets configured to deform the staples.
