Patent ID: 7544007

Claim:
A swivel adapter connectable to, and extending outward from, a head support comprising: an elongated base having upper and lower ends comprising: an outboard first side facing in an outward direction away from the swivel adapter and an inboard side facing in an inward direction, the inboard side including a connector for removably connecting a head support on the inboard side of the base, the connector comprising first engagement teeth for mateably engaging with like engagement teeth of a head support, and a passage therethrough concentric with a longitudinal axis of the connector, and a boss extending from the outboard side in the outward direction and comprising a pivot axis axially aligned with the longitudinal axis of the connector and having a pivot surface; a center adapter pivotably mounted on the pivot surface of the boss, and further comprising: a split bore formed therein and oriented perpendicular to the boss, and a device connector facing in the outward direction, the device connector having second engagement teeth for engageaby contacting like engagement teeth of an additional surgical device, so as to removably hold the additional device; a clamp comprising; a handle pivotally connected to the center adapter on one side of the split bore and pivotal about a handle pivot pin having a handle axis, a rocker pivotally connected to the center adapter on an opposite side of the split bore and pivotal about a rocker pivot pin having a rocker axis, the rocker axis and the handle axis being parallel, a tubular adjuster comprising a tubular body secured to the rocker at a first end and having an opening at a second end, a rod having first and second ends, the second end of the rod telescopically received within the second end of the tubular adjuster and the rod pivotally connected to the handle at the first end thereof, so as to span the split bore; and a biasing means disposed between an internal shoulder of the tubular adjuster and the second end of the rod for facilitating movement of the clamp from a clamped orientation to an unclamped orientation wherein the rod is biased towards a retracted position within the tubular adjuster and applies a clamping force between the handle pivot pin and the rocker pivot pin and opposing sides of the split bore when the clamp is in the clamped orientation the handle being operable to clamp the center adapter on the pivot surface of the boss at a desired orientation and to unclamp the center adapter from the pivot surface of the boss, thereby allowing the center adapter to rotate with respect to the boss so as to locate the device connector at a desired rotated position relative to the boss.
