  • Spine-mounted stereotactic systems and related methods
    Patent number: 11058510
    Abstract: A stereotactic system for positioning a device relative to a spine includes a first frame with an attached first pedicle screw, a second frame with an attached second pedicle screw, and a platform for mounting the device. The lower parts of the frames are horizontally spaced apart, and attachable to the spine by the pedicle screws. The platform is attached to the upper parts of the frames and supported by the frames above the spine. The platform is slidably attached to the upper parts of the frames to adjust a longitudinal position of the platform relative to the frames. The platform is pivotally attached to the upper parts of the frame to adjust a horizontal distance between the lower parts of the frames, while maintaining a constant orientation of the platform.
