Abstract
Embodiments of a limb clamp assembly are shown and described, each having one or more articulated arms for wrapping at least partially around a leg or other extremity, for holding the leg motionless for examination or surgery. The preferred arm or arms extend generally horizontally when open, so that the limb enters the clamp from the side. a strap means may extend around the outside of the arm or arms to further encircle the limb and to close the clamp by its being pulled tight and fastened at each of its ends to the clamp. Preferably, the clamp has one or two arms, each with a joint connecting the arm to a rigid base and a joint connecting two sections of the arm. Preferably, the clamp assembly is used by inserting the limb into the interior of the clamp, swinging a strap up around the outside of the arm or arms, tightening the strap to pull the arms around the limb, and locking the strap to the base. A cam system or gear wheel system are examples of devices for tightening and locking the strap in position.
