Development and Evaluation of a Prototype Camera System for Intraoperative Video Recording of Open Surgery

Intraoperative video enables better surgical training, continued performance enhancement and quality improvement initiatives; however, there exists a lack of technology to reliably and routinely capture high-quality video of open surgical procedures. Using the limitations of previously identified capture systems as innovation targets, we developed a prototype camera system and benchmarked it against existing capture technology using objective and subjective evaluation frameworks. In a simulated OR environment, there was less movement of the prototype camera measured by a physical sensor, and algorithmic video analysis demonstrated more stable, sharper, higher contrast images but with more surgical field obstruction. In the real OR environment, surgeons rated the usability of the prototype more favourably for ‘weight’ and ‘would recommend to a colleague’, and rated the video product higher for ‘camera stability’ but lower for ‘unobstructed view of the surgical field’. This work demonstrates a novel and effective method for intraoperative video capture of open surgery.M.A.S.2021-11-26 00:00:0
