Abstract

A surgical staple driver array for operable use in a surgical staple cartridge. A plurality of first staple drivers is configured to be slidably supported in the surgical staple cartridge. Each first staple driver is configured to operably support at least two first surgical staples thereon that are parallel to each other. A plurality of second staple drivers is configured to be slidably supported in the surgical staple cartridge adjacent to at least one corresponding first staple driver. Each second staple driver supports a single, second surgical staple thereon. The second surgical staple extends in a second direction that is transverse to each of the first surgical staples supported on the at least one adjacent corresponding first staple driver.

Claims

1. A surgical staple driver array for operable use in a surgical staple cartridge, said surgical staple driver array, comprising:

a plurality of first staple drivers configured to be slidably supported in the surgical staple cartridge, each said first staple driver being configured to operably support at least two first surgical staples thereon that are parallel to each other, each first surgical staple comprising a first crown and wherein the first crown of one of the first surgical staples supported on one of said first staple drivers is aligned on a first base axis; and

at least one second staple driver configured to be slidably supported in the surgical staple cartridge, each said second staple driver supporting a single, second surgical staple thereon, the second surgical staple extending in a second direction that is transverse to each of the first surgical staples supported on at least one of said first staple drivers that is adjacent thereto, and wherein another crown of another first surgical staple that is supported on said one of said first staple drivers is aligned on a second base axis that is parallel to said first base axis and wherein said first and second staple drivers are oriented in a line in the surgical staple cartridge such that one of said first staple drivers is located on each axial side of each said second staple driver and wherein each of said first staple drivers comprises a first camming surface and a second camming surface spaced from said first camming surface, wherein each of said second staple drivers comprises a primary camming surface and a secondary camming surface spaced from said primary camming surface, said first camming surface and said primary camming surface being aligned on a first camming axis and said second camming surface and said secondary camming surface being aligned on a second camming axis.

2. The surgical staple driver array of claim 1, wherein said first and second camming axes are transverse to said first and second base axes.

3. The surgical staple driver array of claim 1, wherein a portion of each said first staple driver is configured to be slidably supported in a first wall portion of the surgical staple cartridge and wherein another portion of each said first staple driver is configured to be slidably supported in a second wall portion of the surgical staple cartridge.

4. A surgical staple cartridge, comprising:

a cartridge body comprising a proximal and a distal end;

a plurality of first staple drivers movably supported in said cartridge body, each said first staple driver configured to support two, first surgical staples in corresponding first directions, wherein each said first staple driver comprises;

a first staple support member comprising;

a first distal support column configured to support a first distal leg of a corresponding first surgical staple thereon, said first distal support column being slidably supported in a corresponding first slot in a first wall portion of said cartridge body; and

a first proximal support column configured to support a first proximal leg of the corresponding first surgical staple thereon, wherein each said first staple driver further comprises;

another first staple support member comprising;

another first distal support column configured to support another first distal leg of another corresponding first surgical staple thereon; and

another first proximal support column configured to support another first proximal leg of the another corresponding first surgical staple thereon, said another first proximal support column being slidably supported in a corresponding second slot in a second wall portion of said cartridge body, wherein said surgical staple cartridge further comprises;

at least one second staple driver slidably supported in the surgical staple cartridge adjacent to at least one corresponding said first staple driver, each said second staple driver supporting a single, second surgical staple thereon, the second surgical staple extending in a second direction that is transverse to each of said corresponding first directions, wherein said first and second staple drivers are oriented in a line in the cartridge body such that one of said first staple drivers is located on each axial side of each said second staple driver, each said second staple driver further comprising;

a primary camming surface aligned on a first cam axis; and

a secondary camming surface aligned on a second cam axis.

5. The surgical staple cartridge of claim 4, wherein:

one of the first surgical staples supported on one of said first staple drivers comprises a first crown that is aligned on a first base axis;

another of the first surgical staples supported on said one of said first staple drivers comprises another first crown aligned on another first base axis, wherein said another first base axis is parallel with said first base axis; and

each second staple comprises a second crown that is aligned on a second base axis that is transverse to said first base axis and said another first base axis.

6. The surgical staple cartridge of claim 5, wherein each said first staple support member and said another first staple support member further comprises:

a first camming surface aligned on a first cam axis that extends transversely between said first distal and first proximal support columns; and

a second camming surface aligned on a second cam axis that extends transversely between said another first distal and said another first proximal support columns.

7. The surgical staple cartridge of claim 6, wherein said at least one second staple driver further comprises:

a second staple support member comprising;

a second distal support column configured to support a second distal leg of a corresponding second surgical staple thereon; and

a second proximal support column configured to support a second proximal leg of the corresponding second surgical staple thereon.

8. The surgical staple cartridge of claim 7, wherein each said second staple support member further comprises:

a primary first camming surface adjacent said second proximal support column and aligned on said first cam axis; and

a secondary camming surface adjacent said second distal support column and aligned on said second cam axis.

9. The surgical staple cartridge of claim 7, wherein said cartridge body defines a cartridge axis, wherein said first slot lies along a first slot axis that is transverse to said cartridge axis, and wherein said second slot lies along a second axis that is transverse to said cartridge axis.
