Abstract: The Pedicle Endoscope represents a new way to image the insertion of screws in vertebrae with the aid of fiber optics. The endoscope can operate in the visible and infrared spectra and is used in conjunction with a polyaxial or multiaxial screwdriver assembly. The mechanical assembly is comprised of a screwdriver, a polyaxial or multiaxial shaft, and a pedicle screw. The polyaxial shaft is inserted in the screwdriver and this assembly couples with the pedicle screw. Once this mechanical assembly is integrated, the endoscope is inserted through a bore that runs along the polyaxial shaft and the pedicle screw and it comes out of the screw tip, imaging the progression of the screw as it penetrates the incision in the vertebra. The endoscope consists of three fiber cores, one for imaging and two for illumination and a conduit for irrigation and air suction.

Abstract: The Multi-Thread Iliac Screw represents a novel way to embed fasteners in the ilium by improving fixation of said fasteners in the different parts of the iliac bone tissue. The screw consists of a saddle with a locking screw and fastener with three types of threads to provide a more mechanically stable embedding of the fastener in the iliac bone. The saddle receives a spinal stabilizing rod, which is part of another vertebral mechanical system, and, as such, the saddle provides an anchor point to the stabilizing rod. In another embodiment, the saddle is designed with an integrated rod on its side, which mates to another hollow rod integrated to a cube-shaped connector, thereby replacing the stabilizing rod. The connector provides the interface to the rest of the vertebral mechanical system.

Abstract: The Infrared Endoscopic Probe represents a new instrument to bore pilot holes in vertebra pedicles while imaging the operation in the infrared spectrum with an integrated fiber optics endoscope. The pilot holes are bored to provide entry points for pedicle screws that serve as anchor points for spine stabilizing rods to treat several spine conditions. The device consists of a metal body that terminates in a tapered incision tip, an endoscope that runs inside said metal body, a handle to drive the device into pedicle boney tissue and a fiber optics harness that enters the device handle and is used to connect to imaging, illumination, irrigation and suction devices to enable the endoscopic functions of the device. The fiber optics harness connects to an imaging camera that provides an electrical signal to a monitor to view the operation in real time. A method is described to accomplish this procedure.
