  • Cost-per-case analysis. This analysis includes amortized capital, sterilization costs, disposable/replaceable items, and service-contract costs. The projected 20% is based upon 30 arthroscopic procedures per week. Lazurite LLC. 22-015R.

  • Cost-per-case analysis. See above.
  • Efficiency. In a recent study, 82% of respondents (n=84) indicated that they expect the ArthroFree System to improve safety, and 84% (n=85) indicated that they expect it to improve efficiency. In a comparative simulation study, the set-up, take-down, and processing times of the ArthroFree System were found to be lower than respective times of a conventional camera system.

    Safety. Tests of the Meridiem light engine used in the ArthroFree wireless surgical camera indicate that, even under heavy use, its heat production is minimal: 43°C. 3M™ indicates that their Ioban™ 2 antimicrobial incise drapes have a flash point of 121.1°C. Spradling et al. (2015) measured the peak temperature of a flexible fiber-optic ureteroscope, connected by fiber-optic cable, to be 194.5°C. Smith and Soham (2008) found that fiber-optic light cables can melt polypropylene surgical drapes. Fire prevention guidelines from the American Society of Anesthesiologists, the Anesthesia Patient Safety Foundation, the Emergency Care Research Institute, and the Society of American Gastrointestinal and Endoscopic Surgeons have led many facilities to establish a fire-risk assessment during the surgical “time-out” ahead of each procedure (Jones et al. 2019).

  • Safety and value. On the question of safety, see above. In terms of value and market opportunity: hospital lighting requires more than 10% of a facility’s energy consumption. Lighting, too, generates heat, and thereby boosts the demand for cooling. Healthcare remains a key market for energy-efficient lighting.
