1. A surgical articulation assembly comprising:
a control assembly including first, second, and third user controls rotatable independently of each other, the first user control is in a superposed relation with the second or third user controls; and
an articulatable portion including a first segment and a second segment, the first user control operatively coupled to the first segment such that rotation of the first user control causes displacement of the first segment in a first direction, the second and third user controls operatively coupled to the second segment such that rotation of the second and third user controls causes displacement of the second segment in a second direction and a third direction, respectively, the control assembly and the articulatable portion defining a passage to receive a surgical instrument therethrough, wherein the second user control of the control assembly is in a superposed relation with the third user control.
 
13. A surgical articulation assembly comprising:
a control assembly including first, second, and third user controls rotatable independently about respective first, second, and third axes; and
an articulatable portion operatively coupled to the first, second, and third user controls of the control assembly such that rotation of the first user control articulates the articulatable portion in a first direction, wherein rotation of the second user control articulates the articulatable portion in a first plane and rotation of the third user control articulates the articulatable portion in a second plane, wherein the second user control of the control assembly is in a superposed relation with the third user control, wherein the control assembly and the articulatable portion define a passage extending therethrough, and wherein the passage defines an opening in the control assembly for receiving a surgical instrument therethrough.
