Surgical staple cartridge staple drivers with central support features
View Patent ↗A surgical staple driver. A driver body is configured to be slidably supported in a surgical staple cartridge. The driver body comprises at least two staple support members. Each staple support member is configured to operably support a corresponding staple thereon. The driver body further comprises a first camming surface and a second camming surface that is spaced from the second camming surface. The driver body further comprises at least one aperture that is configured to slidably receive therein a corresponding driver guide formed in the staple cartridge.
1. A surgical staple driver, comprising
a driver body configured to be slidably supported in a surgical staple cartridge, said driver body comprising:
at least two staple support members protruding from said driver body, wherein one of said at least two said staple support members removably supports a corresponding surgical staple along a base axis and wherein another one of said staple support members removably supports another surgical staple along another base axis that transversely intersects said base axis;
a first camming surface;
a second camming surface spaced from said first camming surface; and
at least one aperture in said driver body configured to slidably receive therein a corresponding driver guide formed in the surgical staple cartridge.
2. The surgical staple driver of claim 1 , wherein each of said at least one apertures is located between said first and second camming surfaces.
3. The surgical staple driver of claim 1 , wherein said driver body comprises a distal end and a proximal end and wherein at least one of said proximal end and said distal end is configured to slidably engage another one of said corresponding driver guides.
4. The surgical staple driver of claim 1 , wherein one of said staple support members comprises:
a proximal support column configured to support a proximal leg of a corresponding surgical staple thereon; and
a distal support column configured to support a distal leg of the corresponding surgical staple thereon and wherein another one of said staple support members comprises:
another proximal support column configured to support another proximal leg of another corresponding surgical staple thereon; and
another distal support column configured to support another distal leg of the another corresponding surgical staple thereon and wherein one of said proximal support column and said distal support column is slidably supported in a corresponding slot in a cartridge wall portion of the surgical staple cartridge and wherein one of said another proximal support column and said another distal support column is slidably supported in another corresponding slot in another cartridge wall portion of the surgical staple cartridge.
5. The surgical staple driver of claim 4 , wherein the surgical staple cartridge defines a cartridge axis and wherein said corresponding slot and said another corresponding slot are each transverse to the cartridge axis.
6. The surgical staple driver of claim 5 , wherein the corresponding driver guide is centrally disposed between the cartridge wall portion and the another cartridge wall portion.
7. A surgical staple cartridge, comprising:
a cartridge body defining a cartridge axis and comprising a first cartridge wall and a second cartridge wall spaced from said first cartridge wall, said cartridge body further comprising at least two upstanding driver guides located between said first cartridge wall and said second cartridge wall; and
at least one surgical staple driver, comprising:
a driver body comprising a proximal end configured to slidably engage one of said driver guides and a distal end configured to slidably engage another one of said driver guides;
a first staple support member protruding from said driver body and configured to removably support a first surgical staple thereon; and
a second staple support member protruding from said driver body and configured to removably support a second surgical staple thereon and wherein a portion of said first staple support member is slidably supported in a corresponding slot in said first cartridge wall defining a corresponding slot axis and wherein another portion of said second staple support member is slidably supported in another corresponding slot in said second cartridge wall defining another corresponding slot axis and wherein said corresponding slot axis and said another corresponding slot axis transversely intersect said cartridge axis.
8. The surgical staple cartridge of claim 7 , wherein the first surgical staple comprises a first crown supported on a first base axis and wherein the second surgical staple comprises a second crown on a second base axis that is parallel with said first base axis.
9. The surgical staple cartridge of claim 8 , wherein said second base axis is transverse to said first base axis.
10. The surgical staple cartridge of claim 7 , wherein each said surgical staple driver further comprises at least one aperture therein configured to slidably receive a corresponding additional driver guide therein.
11. A surgical instrument, comprising:
an axially movable sled, comprising:
a first camming member configured to move along a first cam axis; and
a second camming member configured to move along a second cam axis, wherein said surgical instrument further comprises:
a surgical staple cartridge, comprising:
a cartridge body defining a cartridge axis and comprising a first cartridge wall and a second cartridge wall spaced from said first cartridge wall, said cartridge body further comprising at least two upstanding driver guides located between said first cartridge wall and said second cartridge wall; and
at least one surgical staple driver, comprising:
a driver body comprising a proximal end configured to slidably engage one of said driver guides and a distal end configured to slidably engage another one of said driver guides;
a first staple support member protruding from said driver body and configured to removably support a first surgical staple thereon; and
a second staple support member protruding from said driver body and configured to removably support a second surgical staple thereon, wherein a portion of said first staple support member is slidably supported in a corresponding slot in said first cartridge wall defining a corresponding slot axis, wherein another portion of said second staple support member is slidably supported in another corresponding slot in said second cartridge wall defining another corresponding slot axis, and wherein said corresponding slot axis and said another corresponding slot axis transversely intersect said cartridge axis.
12. The surgical instrument of claim 11 , wherein said driver body further comprises:
a first camming surface oriented on one side of each of said driver guides and in axial alignment with said first cam axis; and
a second camming surface oriented on another side of each of said driver guides and in axial alignment with said second cam axis.
13. The surgical instrument of claim 12 , wherein said driver body further comprises at least one aperture therein located between said first and second camming surfaces and being configured to slidably receive a corresponding additional driver guide therein.
