A base-clamp assembly for supporting an instrument relative to a patient position adjacent to an instrument-support rail. The base-clamp assembly may comprise a base, a rail clamp, and an actuator assembly. The rail clamp may attach the base to the rail. A shank clamp may attach a shank to the base. The actuator assembly may be operable for opening and/or closing the rail clamp. A drive assembly may provide for moving a force-applying element relative to the base and a movable rail jaw for closing the rail clamp. The drive assembly may also be operable for opening and closing the shank clamp. |
