Surgical instrument assembly
A surgical instrument assembly comprising a shaft assembly and an end effector is disclosed. The shaft assembly comprises a firing system and a closure system comprising a closing cam. The firing system comprises a first camming member and a second camming member. The closure system is separate and distinct from the firing system. The end effector comprises a first jaw, a second jaw, a cartridge body, and a metal staple matrix. The second jaw is movable relative to the first jaw when a closing motion is applied to the second jaw by the closure cam during a closing stroke. The first jaw is configured to be engaged by the first camming member and the second jaw is configured to be engaged by the second camming member during a staple firing stroke. The metal staple matrix comprises a plurality of staples and a metal staple-connecting member interconnecting the staples.
1. A surgical instrument assembly, comprising:
a shaft assembly, comprising:
a firing system comprising a first camming member and a second camming member; and
a closure system comprising a closure cam, wherein said closure system is separate and distinct from said firing system; and
an end effector, comprising:
a first jaw;
a second jaw movable relative to said first jaw when a closing motion is applied to said second jaw by said closure cam during a closing stroke, wherein said first jaw is configured to be engaged by said first camming member and said second jaw is configured to be engaged by said second camming member during a staple firing stroke;
a cartridge body; and
a metal staple matrix, comprising:
a plurality of staples, wherein each said staple comprises a staple base and a staple leg extending from said staple base; and
a metal staple-connecting member interconnecting said staples.
2. The surgical instrument assembly of claim 1 , wherein said staple-connecting member connects said staple bases to each other.
3. The surgical instrument assembly of claim 1 , wherein said staple-connecting member is positioned adjacent said staple bases of said plurality of staples.
4. The surgical instrument assembly of claim 1 , wherein said staple-connecting member comprises a first staple-connecting portion, and wherein said metal staple matrix further comprises a second staple-connecting portion connecting a said staple base to a said staple leg of another staple of said plurality of staples.
5. A surgical instrument assembly, comprising:
a shaft assembly, comprising:
a firing system; and
a closure system separate and distinct from said firing system; and
an end effector, comprising:
a first jaw;
a second jaw movable relative to said first jaw when a closing motion is applied to said second jaw;
a cartridge body; and
a fastener matrix, comprising:
a plurality of fasteners, wherein each said fastener comprises a fastener base and a fastener leg extending from said fastener base; and
a metal fastener-connecting member connecting more than one said fastener to each other, wherein said fasteners are configured to move relative to said metal fastener-connecting member during a fastener firing actuation of said surgical instrument assembly.
6. The surgical instrument assembly of claim 5 , wherein said metal fastener-connecting member comprises a first fastener-connecting portion, and wherein said fastener matrix further comprises a second fastener-connecting portion connecting a said fastener base to a said fastener leg of another fastener of said plurality of fasteners.
7. A surgical instrument assembly, comprising:
a shaft assembly, comprising:
a firing system; and
a closure system separate and distinct from said firing system; and
an end effector, comprising:
a first jaw;
a second jaw movable relative to said first jaw when a closing motion is applied to said second jaw;
a cartridge body; and
a staple strip, comprising:
a plurality of staples, wherein each said staple comprises a staple base and a staple leg extending from said staple base; and
a metal staple-connecting member mounting said staples in a longitudinal array.
8. The surgical instrument assembly of claim 7 , wherein said metal staple-connecting member connects said staple bases to each other.
9. The surgical instrument assembly of claim 7 , wherein said staple-connecting member is positioned adjacent said staple bases of said plurality of staples.
10. The surgical instrument assembly of claim 7 , wherein said metal staple-connecting member comprises a first staple-connecting portion, and wherein said staple strip further comprises a second staple-connecting portion connecting a said staple base to a said staple leg of another staple of said plurality of staples.
