Summary

The arthroscope tip is too cool to burn skin but can singe drapes. However, the light cable end, at 101°C, poses a burn risk to patients and drapes, potentially causing combustion.

Area of Science:

  • Orthopaedic Surgery
  • Biomedical Engineering
  • Surgical Safety

Background:

  • Anecdotal reports suggest potential thermal risks associated with arthroscopic equipment.
  • The thermal output of arthroscopic instruments, specifically the arthroscope tip and light cable end, has not been systematically evaluated.
  • Understanding these thermal properties is crucial for preventing surgical site injuries and equipment damage.

Purpose of the Study:

  • To investigate the thermal output of the arthroscope tip and light cable end.
  • To assess the potential for thermal burns to surgical drapes and patient tissues during orthopaedic arthroscopy.
  • To provide recommendations for safe handling of arthroscopic light sources.

Main Methods:

  • Temperature measurements were taken at the arthroscope tip and light cable end.

  • Experiments were conducted to evaluate the potential for singeing and combustion of surgical drapes at varying distances from the light cable end.
  • Simulated contact scenarios were assessed for thermal injury potential.

    • Main Results:

    • The arthroscope tip registered a temperature of 41.9°C, insufficient to cause skin burns but capable of singeing drapes without combustion.
    • The light cable end reached 101°C, posing a significant risk for skin burns and rapid combustion of disposable arthroscopic drapes within 0.5 cm.
    • Combustion of drapes occurred within seconds when the light cable end was in direct contact or close proximity.

    Conclusions:

    • The light cable end presents a substantial thermal hazard during arthroscopic procedures.
    • Recommendations include connecting the light cable before activating the light source and avoiding contact between the illuminated light cable end and surgical drapes.
    • Implementing a retractable shield on the light cable end is suggested to mitigate combustion risks.
