    摘要: An apparatus for use in preparing the intervertebral disc space. The apparatus includes a powered disc cutter that can be inserted through a tube and into the disc space. Once inside the disc space, the cutter can be rotated on its axis and articulated through the disc space to break up and disconnect the disc tissue from the surrounding disc tissue and disc annulus. The device is powered by a handheld driver that utilizes a motor to impart motion, such as rotary motion, to an elongated shaft assembly having a cutting tool or assembly pivotably attached to the distal end thereof. The cutting tool is mounted to the end of the drive shaft assembly by a linkage so that the shaft may be inserted in a straight configuration down a narrow access port. The cutting assembly can spin on its axis while being articulated providing access to the intervertebral space.

    摘要: Pedicle-based intradiscal fixation devices, systems, instruments, and methods thereof. A pedicle-based intradiscal implant for stabilizing an inferior vertebra and a superior vertebra may include a bendable rod configured to engage bone, a bone fastener defining a channel for receiving the bendable rod, and a locking cap for securing the bone fastener and the bendable rod. The implant may be positioned through a pedicle of an inferior vertebra and the bendable rod may be deployable into the vertebral body of the inferior vertebra, through the disc space, and into the vertebral body of the superior vertebra to stabilize the spine.
