Summary
A novel Extender lighting device significantly improves surgical illumination in difficult wounds, providing brighter and more evenly distributed light compared to traditional operating room (OR) lights.
Area of Science:
- Medical Devices
- Surgical Technology
- Illumination Engineering
Background:
- Open surgery often faces challenges with adequate lighting in deep or difficult-to-access wounds.
- Conventional lighting solutions, such as operating room (OR) lights and head-mounted lights, may have limitations in directing and distributing light effectively within surgical sites.
Purpose of the Study:
- To design and evaluate a new lighting device, the Extender add-on, for open surgery.
- To compare the illumination quality of the Extender prototypes against conventional surgical lighting methods.
Main Methods:
- A cylindrical setup was engineered to simulate a pelvic wound for light distribution measurements.
- Light output and angular distribution were measured for head-mounted lights, OR lights, and Extender prototypes.
Main Results:
- Extender prototypes delivered 12.2 lumens within the simulated wound, surpassing the 5.7 lumens from head-mounted lights.
- Extenders provided smooth light distribution from 0° to 180°, while head-mounted and OR lights offered distribution only from 115° to 180°.
Conclusions:
- The Extender add-on demonstrates promising performance for surgical illumination, offering superior light quantity and distribution.
- Further refinement in Extender production is anticipated to enhance illumination performance even more.
