Abstract

Claims (55)

1. A surgical staple cartridge, comprising:

a cartridge body comprising:

a proximal end;

a distal end;

a longitudinal axis;

a deck configured to support patient tissue, wherein said deck extends along the longitudinal axis between said proximal end and said distal end;

a first longitudinal row of first staple cavities defined in said deck;

a second longitudinal row of second staple cavities defined in said deck;

a third longitudinal row of third staple cavities defined in said deck;

a first projection extending from said deck, wherein said first projection at least partially extends around a distal end of the most distal first staple cavity, wherein said first projection comprises a first raised portion and a first ramp sloping distally along the longitudinal axis from said first raised portion to said deck;

a second projection extending from said deck, wherein said second projection at least partially extends around a distal end of the most distal second staple cavity, wherein said second projection comprises a second raised portion and a second ramp sloping distally along the longitudinal axis from said second raised portion to said deck, and wherein the first ramp touches the second ramp; and

a third projection extending from said deck, wherein said third projection at least partially extends around a distal end of the most distal third staple cavity, and wherein said third projection comprises a third raised portion and a third ramp sloping distally along the longitudinal axis from said third raised portion to said deck; and

staples removably stored in said first staple cavities, said second staple cavities, and said third staple cavities.

2. The surgical staple cartridge of claim 1 , wherein a portion of said first ramp and a portion of said second ramp define a continuous ramp surface that slopes downward towards said deck.

3. The surgical staple cartridge of claim 1 , wherein said first ramp comprises a first ramp end terminating at said deck at a first location, wherein said second ramp comprises a second ramp end terminating at said deck at a second location that is longitudinally aligned with the first location, and wherein said most distal first staple cavity and said most distal second staple cavity are longitudinally offset.

4. The surgical staple cartridge of claim 1 , wherein said first longitudinal row of first staple cavities is adjacent to said second longitudinal row of second staple cavities.

5. The surgical staple cartridge of claim 1 , wherein said first projection and said second projection define an interconnected raised portion that at least partially extends around a proximal end of the most distal first staple cavity and connects to said second raised portion of said second projection.

6. A surgical staple cartridge, comprising:

a cartridge body comprising:

a proximal end;

a distal end;

a deck configured to support patient tissue, wherein said deck comprises a deck surface extending longitudinally from said proximal end toward said distal end;

a first longitudinal row of first staple cavities defined in said deck surface;

a second longitudinal row of second staple cavities defined in said deck surface;

a third longitudinal row of third staple cavities defined in said deck surface;

proximal projections extending from said deck surface, wherein each said proximal projection surrounds a proximal end of a said first staple cavity, a proximal end of a said second staple cavity, or a proximal end of a said third staple cavity; and

distal projections extending from said deck surface, wherein each said distal projection surrounds a distal end of a said first staple cavity, a distal end of a said second staple cavity, or a distal end of a said third staple cavity, and wherein said distal projections comprise:

a first distal projection corresponding to the most distal first staple cavity, wherein said first distal projection comprises a first raised portion and a first ramp sloping longitudinally from said first raised portion to said deck surface;

a second distal projection corresponding to the most distal second staple cavity, wherein said second distal projection comprises a second raised portion and a second ramp sloping longitudinally from said second raised portion to said deck surface, wherein the first ramp and the second ramp are touching; and

a third distal projection corresponding to the most distal third staple cavity, wherein said third distal projection comprises a third raised portion and a third ramp sloping longitudinally from said third raised portion to said deck surface; and

staples removably stored in said first staple cavities, said second staple cavities, and said third staple cavities.

7. The surgical staple cartridge of claim 6 , wherein a portion of said first ramp and a portion of said second ramp to define a continuous ramp surface that slopes downward towards said deck surface.

8. The surgical staple cartridge of claim 7 , wherein said first ramp comprises a first ramp end terminating at said deck surface, wherein said second ramp comprises a second ramp end terminating at said deck surface, wherein the most distal first staple cavity and the most distal second staple cavity are longitudinally offset, and wherein said first ramp end and said second ramp end are longitudinally aligned.

9. The surgical staple cartridge of claim 8 , wherein said first longitudinal row of first staple cavities is adjacent to said second longitudinal row of second staple cavities.

10. The surgical staple cartridge of claim 6 , wherein said proximal projections comprise a first proximal projection corresponding to the most distal first staple cavity, and wherein said first proximal projection and said second distal projection connect to form an interconnected raised portion.

11. A surgical staple cartridge, comprising:

a cartridge body comprising:

a proximal end;

a distal end;

a deck configured to support patient tissue, wherein said deck comprises a deck surface extending longitudinally from said proximal end toward said distal end;

a first staple cavity defined in said deck surface;

a second staple cavity defined in said deck surface, wherein said second staple cavity is laterally offset from said first staple cavity;

a third staple cavity defined in said deck surface, wherein said third staple cavity is laterally offset from said first staple cavity and said second staple cavity;

projections extending from said deck surface, wherein said projections comprise:

a first distal projection surrounding a distal portion of said first staple cavity, wherein said first distal projection comprises a first raised portion and a first ramp sloping longitudinally from said first raised portion to said deck surface;

a second distal projection surrounding a distal portion of said second staple cavity, wherein said second distal projection comprises a second raised portion and a second ramp sloping longitudinally from said second raised portion to said deck surface, wherein said first ramp and said second ramp are touching;

a third distal projection surrounding a distal portion of said third staple cavity, wherein said third distal projection comprises a third raised portion and a third ramp sloping longitudinally from said second raised portion to said deck surface; and

staples removably stored in said first staple cavity, said second staple cavity, and said third staple cavity.

12. The surgical staple cartridge of claim 11 , wherein a portion of said first ramp and a portion of said second ramp define a continuous ramp surface that slopes towards said deck surface.

13. The surgical staple cartridge of claim 11 , wherein said first ramp comprises a first ramp end terminating at said deck surface, wherein said second ramp comprises a second ramp end terminating at said deck surface, wherein said first staple cavity and said second staple cavity are longitudinally offset, and wherein said first ramp end and said second ramp end are longitudinally aligned.
