Classification: CPC A | IPC A

Claim 9:
10. A surgical instrument, comprising:
an elongate shaft defining a longitudinal axis;
an end effector extending from said elongate shaft;
an articulation joint, wherein said end effector is rotatable relative to said elongate shaft about an articulation axis defined by said articulation joint;
a first articulation driver positioned on a first side of said longitudinal axis, wherein said first articulation driver is pivotally coupled directly to a proximal end of said end effector;
a second articulation driver positioned on a second side of said longitudinal axis opposite said first side, wherein said second articulation driver is pivotally coupled directly to said proximal end of said end effector; and
a rotary articulation member positioned in said elongate shaft intermediate said first articulation driver and said second articulation driver; and
a proximal articulation driver translatable longitudinally to apply linear articulation motions to said first articulation driver to translate said first articulation driver, wherein said proximal articulation driver is translatable relative to said first articulation driver, wherein said rotary articulation member operably couples said first articulation driver to said second articulation driver such that when said first articulation driver is translated proximally by said proximal articulation driver, said second articulation driver is translated distally to rotate said end effector about said articulation axis in a first direction, and wherein said rotary articulation member operably couples said first articulation driver to said second articulation driver such that when said first articulation driver is translated distally by said proximal articulation driver, said second articulation driver is translated proximally to rotate said end effector about said articulation axis in a second direction opposite said first direction.
