1. A surgical instrument comprising:
an end effector comprising an end effector base and an articulated jaw rotatably mounted to the end effector base for rotation of the articulated jaw relative to the end effector base around an articulated jaw pivot axis that is fixed relative to the end effector base, wherein the end effector base comprises an opposing jaw; and
a first actuation mechanism comprising a first pulley and a first cable segment,
wherein the first pulley is mounted for rotation relative to the end effector base,
wherein the first cable segment is interfaced with a sector of the first pulley,
wherein the first cable segment has a distal end that is attached to the articulated jaw, and
wherein the first actuation mechanism is operable to retract the first cable segment to cause the articulated jaw to apply a grasping force to a tissue disposed between the articulated jaw and the opposing jaw.
