Illumination in Spinal Surgery Depending on Different Approaches and Light Sources

Area of Science:

• Neurosurgery
• Surgical Technology
• Medical Imaging

Background:

• Adequate visualization of the surgical field is critical for successful outcomes in spine surgery.
• Minimally invasive and deep surgical approaches present unique visualization challenges.

Purpose of the Study:

• To compare the effectiveness of various light sources and auxiliary devices for improving visualization in simulated deep spinal surgical approaches.
• To identify optimal illumination strategies for microsurgical spinal procedures.

Main Methods:

• A simulated deep spinal surgical environment was created using an isolated box.
• Multiple light sources (microscope, operating room lamp, headlamp) and auxiliary devices (tubes with/without optical fibers, retractors, endoscope) were tested.
• Illuminance levels were measured for different device combinations.

Main Results:

• Significant variations in operating field illumination were observed based on the combination of light sources and auxiliary devices.
• Tubes with optical fibers demonstrated superior performance for non-microscopic approaches.
• Smaller diameter tubes resulted in higher illuminance at the surgical focus.

Conclusions:

• The combination of a surgical microscope and an optical fiber tube is recommended for deep microsurgical spinal approaches.
• Endoscopes provide illumination levels comparable to surgical microscopes.
