  • Patent number: 10588666
    Abstract: A modular polyaxial bone screw includes a poly-axial bone screw, a polyaxial tulip head, and a collet disposed within the tulip head, the collet interacting with the bone screw and tulip head providing an interference fit with the bone screw head to lock orientation of the tulip head on and relative to the bone screw. Inner configurations of the tulip head interact with outer configurations of the collet to lock axial and/or rotational position of the collet within and relative to the tulip head, and thus about the bone screw head. The collet also has a resilient, tapered base with a plurality of slots in and about its end that allow the end to splay outwardly over and upon the head of the bone screw to create a snap or frictional interference fit between the splayed collet and the bone screw head when a spine rod is fixed in the tulip head.

  • Patent number: 8702602
    Abstract: An exoscope serves for observing and illuminating an object field on a patient from a position set apart from the patient's body. A lens system serves to observe the object field and an illumination serves to illuminate the object field. A distance between the lens system and the object field can be modified by a bracket. A shaft comprises on its distal end a head member that is widened in comparison to it, so that the illumination reaches into the distal-side head member. Positioned in the head member is at least one radiating illumination unit whose radiant characteristic can be adjusted in such a way that the object field can be illuminated homogeneously at all possible distances from the lens system. Supply lines for the at least one illuminating unit are positioned in the shaft.

  • Patent number: 8308769
    Abstract: Improved implant devices and methods for interspinous distraction distribute the load of interspinous distraction so that the entire load is not bearing on the interspinous surfaces. The implant device has a narrow midsection and two wider, flange-shaped outer sections. The wider, flange-shaped outer sections can be tightened to bear against the thicker bony portions of the spinous processes to support some of the load. Optionally, the wider, flange-shaped outer sections can be configured with pins that will penetrate and engage the thicker bony portions of the spinous processes, which will increase the load bearing potential of the wider, flange-shaped outer sections. Additionally, the wider, flange-shaped outer sections and the pins will help to stabilize the joint. The joint stabilization may help to prevent further dislocation of the vertebra that occurs with spondylolisthesis.

  • Patent number: 8262705
    Abstract: The invention is directed to a bone plate system. The bone plate system comprises a base plate having two generally parallel elongated screw slots extending therethrough. Two bone screws are provided that are capable of securing the base plate to a bone by insertion through the screw slots into the bone. Each bone screw has a screw head and a threaded portion extending therefrom. An interference device is attached to the base plate and retains the bone screws while permitting the bone screws to toggle and to controllably slide in the screw slots of the base plate. This design is particularly useful for joining adjacent vertebral bodies, as it permits controlled settling of the vertebral bodies, thereby enhancing the healing process.
