Abstract
An articulating tool includes proximal, central and distal portions, an articulation mechanism, and first and second articulation locks. The articulation mechanism includes a pair of links, the pair comprising a proximal link on the proximal portion of the tool and a distal link on the distal portion of the tool. The first articulation lock has an engaged position and a disengaged position. When in the engaged position, the first articulation lock impedes movement of the proximal link relative to the central portion about a yaw axis, and corresponding relative movement of the distal link. The second articulation lock also has an engaged position and a disengaged position. When in the engaged position, the second articulation lock impedes movement of the proximal link relative to the central portion about a pitch axis, and corresponding relative movement of the distal link.
