Definitions

  • This application relates to devices and instruments for the treatment of the spine.
  • this application relates to devices and instruments for treating collapsed disc spaces and Sacroiliac joint (SI) spaces. More particularly, this application relates to the instruments and methods for cleaning and expanding disc spaces.
  • SI Sacroiliac joint
  • Spinal fusion is one of the primary treatment options for a variety of spinal conditions due to various degenerative, neoplastic, traumatic, and infectious processes.
  • achieving spinal fusion requires bony growth between two or more adjacent spinal vertebrae.
  • a collapsed disc is a subset of the general spinal fusion and may require specialized instrumentation due to the nature of the collapsed condition where no disc material might be present. Treating SI joint spaces may use similar instrumentation.
  • cleaning the disc space or tight joint is facilitated with a reciprocating motion of a double action rasp head having a two-sided grit pattern that cleans the superior and inferior part of the space at the same time.
  • the head portion can also be expanded and deployed to act as an implant for bone fusion.
  • a reciprocating double rasp instrumentation system for the cleaning of the bony growth and irregular surface of a collapsed disc space.
  • various instruments and methods are provided to generate reciprocating motion for cleaning out collapsed disc or joint spaces.
  • the instruments include gear mechanisms that facilitate operation under power at high RPMs.
  • the instrument includes a reciprocating rasp configured to be expandable in the vertical direction, which increases the material-removing ability in the axial direction in a controlled manner.
  • the rasp blades serve as a spacer that keeps the disc or joint spaced apart during the injection of fusion material.
  • the side-to-side motion is a single back-and-forth motion or reciprocation motion with a single-action arm or double-action arms.
  • a device for preparing a space between adjacent bone segments includes a disruption head having a first disruption member and a second disruption member, wherein the first and second disruption members reciprocate relative to one another.
  • the adjacent bone segments may be vertebral bones, and the disruption head may be sized and configured to be inserted between the vertebral bones.
  • the adjacent bone segments may be bones of a sacroiliac joint, and the disruption head may be sized and configured to be inserted between the bone segments of the sacroiliac joint.
  • a device for preparing a space between adjacent bone segments includes a delivery instrument, a tissue disruption member, and a tissue removal member.
  • the tissue disruption member may include an elongated body with openings and the tissue removal member may be located within a lumen of the elongated body.
  • FIG. 1 a is a side view of one embodiment of a reciprocating double rasp device, in accordance with the present disclosure.
  • Fig. 1 b is a partial cross-sectional view showing the reciprocating device with a yoke and worm gear system in a neutral position.
  • Fig. 1 c is a partial cross-sectional view showing the reciprocating device with a yoke and worm gear system in an offset position.
