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
- Because there are two small teeth at the distal end of the medial blade, the retractor does not slip.
- The retractor is not able to rotate accidentally as it locks onto the handle. The handle, in turn, can be rotated at will.
- 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.
