Dr. Darshan Patel, MD, a skilled urologist and assistant professor at the UCSD School of Medicine, identified a critical safety hazard in operating rooms caused by dangerously hot fiber optic cords used in laparoscopic, thoracoscopic, and arthroscopic surgeries. These cords, essential for delivering illumination to enclosed body cavities, can reach temperatures of 262°C, posing risks of severe burns to patients and fires when left unattended on top of patients. Instances of detached light cables resting on surgical drapes have resulted in full-thickness skin burns within mere seconds, endangering patients and staff while potentially leading to lawsuits and financial strain on hospitals. The LightLok project focuses on designing a retrofitted, autoclavable attachment that accommodates diverse light cord specifications, prevents thermal injuries, and ensures single-use safety—all without compromising surgical procedures' efficiency or sterility.
