  • Patent number: 11931019
    Abstract: A clamp for a surgical retractor system. The clamp has a tapered conically shaped washer against and through which clamping force is applied to place the clamp in a clamped position. The clamping force is applied by a cam head connected to a central shaft. A locking pin connects the cam head to the shaft. Apertures are provided in the clamp for receiving rod ends of a surgical retractor. Such apertures are circular and are positioned to be closer to the top and bottom edges of the clamp portion of the clamp than to the end edge of the clamp portion.

  • Publication number: 20220000467
    Abstract: A retractor system can include a ring frame and a clamp. The ring frame can include a first ring segment and a second ring segment detachably joined to a first ring segment at a joint. The joint can be contained within a cross section of the ring frame that corresponds to a cutting plane perpendicular to an outer surface of the ring frame. The clamp can include an adjustment screw and a first set of jaws and a second set of jaws. The first set of jaws and second set of jaws can define a first aperture configured to receive the ring frame. Rotation of the adjustment screw in a tightening direction can cause the first set of jaws to engage the outer surface of the ring frame and apply a first clamping force to the outer surface of the ring frame received by the first aperture.
