    Area of Science:

    • Surgical Instrumentation
    • Medical Device Design
    • Ophthalmology/Neurosurgery (implied)

    Background:

    • Traditional surgical procedures often rely on external lighting systems like overhead lights or headlights.
    • These external systems can be cumbersome, obstruct the surgical view, and may not provide optimal illumination.
    • Direct visualization of critical anatomical structures is paramount for surgical success.

    Purpose of the Study:

    • To introduce a novel ramus retractor integrated with a variable high-intensity light source.
    • To evaluate the efficacy of this integrated lighting system in improving surgical field visibility and access.
    • To assess the practical benefits of the device over a five-year period.

    Main Methods:

    • Design and development of a ramus retractor incorporating a variable high-intensity light source.

    Related Experiment Videos

  • Clinical application of the modified retractor in surgical procedures over a five-year period.
  • Qualitative assessment of visibility, access, and usability compared to conventional methods.

    • Main Results:

    • The designed ramus retractor offers reliable, compact, and sterilizable functionality.
    • Direct, high-intensity visibility of the surgical field was achieved consistently.
    • Elimination of the need for external surgical lights, headlights, or spotlights was demonstrated.

    Conclusions:

    • The integrated light source in the ramus retractor significantly enhances direct visualization and identification of surgical structures.
    • This device provides a reliable, compact, and sterilizable solution for improved surgical field illumination.
    • The five-year clinical use confirms the practical advantages over traditional lighting methods in surgery.
