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.

Abstract: The present invention relates to an apparatus for adapting a non-cylindrical serrated surgical retractor blade handle to the cylindrical bore of a universal joint. The apparatus includes an adaptor housing having a retractor handle passageway, at least a portion of the retractor handle passageway being configured to receive the slideable insertion of a non-cylindrical retractor blade handle. The adaptor housing is configured for rotational insertion into the cylindrical bore of a clamping member, thereby allowing the adaptor housing, the non-cylindrical retractor blade handle, and an attached retractor blade, to rotate about the longitudinal axis of the non-cylindrical retractor blade handle.
