Retractor with a Lighting System for a Herniated Disc

Retractor with a lighting system for a herniated disc at the distal end for lumbar intervertebral hernia surgery

The principle of a retractor designed specifically for lumbar hernia repair is based on 2 rules:

  • standard access (expansion, from minimal to wide): open pipe principle; the retractor blades act as two pieces of an imaginary 10mm surgical sheath; they remain closed during insertion, later open to the desired size
  • retraction stability

Advantages of the method used for lumbar intervertebral hernia surgery

  1. Because there are two small teeth at the distal end of the medial blade, the retractor does not slip.
  2. The retractor is not able to rotate accidentally as it locks onto the handle. The handle, in turn, can be rotated at will.
  3. Optimal viewing conditions: high illumination depth. Fiberglass fibers are inserted at the distal end of both retractor blades to provide a good view of the surgical field. Therefore, the surgeon does not need a headlamp, which makes it possible to carry out the operation using optical magnification (even with the microscope or magnifier turned off) or without it.
