Abstract
Minimally invasive surgery, specifically endoscopy, is a vital component in modern surgical healthcare. Due to the challenging nature of operating through a restricted endoscopic camera view, novice surgeons must master navigating surgical volumes effectively and efficiently. One of the specific focus areas for these inexperienced surgeons is maintaining the horizon of the camera in the surgical volume. Alongside traditional cadaver training, surgeons use mixed-reality surgical training simulators to improve their surgical skills. In this work, we propose a new method of training novice users in the proper method of maintaining camera horizon alignment in an arthroscopic knee procedure. We ran a study with 21 medical novices on a commercially available surgical simulator. We provided automated verbal cues, digital sine wave audio, or a commercially available visual horizon bar to see if an improvement in performance could be found over the control group that received no additional feedback for the camera horizon. We examined the Overall Workload of the participants, along with the misalignment time of the camera horizon and the procedure time. Results from the study showed that the verbal cues improved procedure time and Overall Workload, and the visual horizon bar improved the horizon misalignment time. Digital sine wave audio was not effective overall.
