Abstract
A universal joint apparatus comprises clamps, a locking mechanism, and a rod connecting the clamps and the locking mechanism. At least one clamp is a scissors clamp, i.e. a clamp comprising two segments fastened by a pivot. The scissors clamp generates extra compressive force on the object being held, providing a stable and rigid universal joint. Clamps are able to rotate with respect to each other, allowing for greater flexibility in usage. The universal joint apparatus is capable of being added to a support frame between other components. In one embodiment of the invention, the universal joint includes a dedicated retractor blade handle to ensure that the locked position of the cam handle is oriented substantially away from the operative site.
