Claim:
1. A tool, comprising: an articulation mechanism comprising a pair of links, the pair including a proximal link on a proximal portion of the tool and a distal link on a distal portion of the tool, the mechanism adapted such that movement of the proximal link causes corresponding relative movement of the distal link; an end effector coupled to the distal link; an elongated shaft extending along a longitudinal axis between the proximal and distal links; a rotating member operable to rotate the end effector about an end effector axis; and an articulation lock comprising a rotating clamp component configured to interlock with a base about a first axis and to interlock with a cover component about a second axis to maintain the end effector in a fixed orientation with respect to the shaft without affecting rotation of the end effector, the first axis and the second axis being perpendicular to the longitudinal axis.
