Posterior Lumbar MIS Tunnel system

  1. Lumbar – Tailored Modularity
    Custom – engineered for posterior lumbar anatomy. Interchangeable retractors, distractors, and bone hooks adapt to L1–S1 segments, matching disc heights and spinal curves for precise fit.
  2. Multi – Axis Retraction Control
    Dual – action retractors deliver lateral and vertical distraction. They stabilize the surgical field, exposing lamina, facet joints, and nerve roots with clarity.
  3. Minimally Invasive Muscle Preservation
    The low – profile tunnel design spares paraspinal muscles. Compared to open surgery, it cuts muscle atrophy and postoperative back pain.
  4. Stepwise Precision Adjustment
    Ratchet locks and scale – marked components enable measurable, step – by – step distraction. This ensures consistent tissue pressure during surgery.
  5. Imaging & Illumination Ready
    Channels integrate with endoscopes and cold light sources. They support real – time visualization for decompression or fusion procedures.

Posterior Lumbar MIS Tunnel System: What Is It?

specialized access platform for posterior lumbar surgeries. It combines retraction, distraction, and stabilization tools into one system. By forming a controlled, minimally invasive tunnel, it allows precise fusion, decompression, and fracture repair — all while safeguarding spinal muscles.

Applications of the System

  1. MIS – TLIF (Transforaminal Lumbar Interbody Fusion)
    Expands the intervertebral space for cage insertion. It maintains stability during bone grafting and screw placement.
  2. Lumbar Spinal Decompression
    Opens the spinal canal to ease stenosis. It safely retracts dura and nerves during laminotomy or foraminotomy.
  3. Lumbar Fracture Fixation
    Stabilizes burst or compression fractures. It aids in pedicle screw insertion and vertebral realignment.
  4. Spondylolisthesis Correction
    Reduces slipped vertebrae. It provides distraction to restore disc height and spinal alignment.
  5. Surgical Skill Training
    Offers a realistic lumbar MIS setup. It helps trainees master retraction and fusion techniques in a controlled environment.
