The instrument (10) further includes a handle member (12) configured to be attached to the proximal end of the elongate member (14), the handle member operatively associated with a rotation mechanism (22). The instrument also includes an end effector (16) configured to be attached to the distal end of io the elongate member, the end effector operatively associated with an articulation mechanism and configured to be pivotable throughout a plurality of directions relative to the longitudinal axis of the elongate member. A software algorithm is used to identify, track, and control directional movement of the end effector in accordance with rotational movement of the elongate member.1/3 2Ose C"Ij ----- L
