  • Patent number: 10441430
    Abstract: A spinal implant has proximal and distal regions, and includes upper and lower bodies. A proximal adjustment assembly is disposed between the upper and lower bodies in the proximal region of the spinal implant and is adjustably coupled to the upper and lower bodies, and a distal adjustment assembly is disposed between the upper and lower bodies in the distal region of the spinal implant and is adjustably coupled to the upper and lower bodies. The proximal and distal adjustment assemblies are independently movable with respect to each other, both concurrently and alternately, to change a vertical height of at least one of the proximal or distal regions of the spinal implant. A set screw is removably disposed within the proximal region of the spinal implant to lock the vertical height of the proximal and distal regions of the spinal implant.

  • Patent number: 10438511
    Abstract: A spine surgery modeling system simulates the spine with various vertebral body or disc conditions and allows a user to make adjustments and examine the three dimensional outcome of such adjustments. The spine surgery modeling system includes a spine model and a drive mechanism. The spine model has vertebral bodies and a disc space defined between adjacent vertebral bodies. The drive mechanism includes a worm gear, a worm, a rigid shaft, and a button. The worm engages the worm gear such that rotation of the worm causes rotation of the worm gear. The rigid shaft extends through a through hole defined in the worm and is configured to rotate the worm. The button is operatively engaged with the worm gear such that rotation of the worm gear causes movement of the button between collapsed and expanded states to change a height of the disc space.

  • Patent number: 10405841
    Abstract: Devices, systems and methods for minimally open orthopedic spine surgery are disclosed. A first flexible screw-based retractor is designed to be coupled to each pedicle screw inserted into adjacent vertebral bodies. A retractor system is provided in which a first retractor blade is mounted to one of the screws and a second movable retractor blade is moved away from the first blade, in a medial direction, to create a working channel through which the disc space may be accessed for passing instruments and implants. Light may be incorporated into the device to illuminate the surgical field. One or all of the retractor blades may be made of a sterilizable plastic or metal and be disposable or reusable.

  • Patent number: 10405896
    Abstract: A rod reducer including a housing, a plurality of arm members, an anvil, a shaft, a sleeve, and a plurality of locking feet. The shaft and locking feet are coupled to the anvil. The housing is slidably disposed within a cavity of the sleeve and defines an opening to receive the shaft. The locking feet are additionally coupled to the sleeve and are pivotable between an engaged configuration with the sleeve in a distal position with respect to the anvil and a released configuration with the sleeve in a proximal position. In the engaged configuration an engagement surface of the locking feet couple to an outer housing of a dual layered housing of a bone screw such that proximal translation of the shaft drives the outer housing proximally with respect to an inner housing of the bone screw into a partially locked or locked configuration.
