An inertial sensor‐based system designed to measure and prevent undesired camera rotation during endoscopic sinus surgery

Abstract

Background: Maintaining a stable visual horizon during endoscopic sinus surgery is essential to preserve spatial orientation. A constant camera movement generates a rotation which tilts the operating field's view, producing a visuomotor incongruence with detrimental effects in surgical performance and safety, especially above 15 o. We aimed to study this phenomenon on endoscopic sinus surgery in order to prevent it.Methods: We developed a system that can be attached to any conventional endoscopic camera and can measure camera movement parameters and their variation from a reference position, feeding back this information in real-time as a reference guide overlay over the original image to aid in maintaining a stable visual horizon. A pilot study was conducted to test the utility and feasibility of the system in human cadaveric specimens, comparing similar tasks performed with and without the reference guides.Results: Camera roll was prospectively measured in 18 tasks. Globally, there was a 52.2% (± 18.3%) reduction in this parameter when the reference guides were active. Specifically, there was 86.8% reduction in the total amount of time where camera roll was above 15o. The impact of the reference guides, nonetheless, was greater in inexperienced participants. All the comparisons were statistically significant (p < 0.05).

A Novel Device to Prevent Undesired Arthroscopic Camera Rotation

“…The system created by Viera-Artiles, et al, which is inexpensive and adjustable to every surgical camera, could overcome this limitation, inherent to the technique. Head and neck trainees were able to perform varied surgical gestures with higher accuracy when the gyroscopic sensor was attached to the camera [3]. During our experience in knees, it was noted that the system provided immediate visual warning when the camera tilted excessively in relation to the operational plane.…”

“…Viera-Artiles, et al, recently developed "An inertial sensor-based system designed to measure and prevent undesired camera rotation during endoscopic sinus surgery" [3]. By means of this instrument, camera rotation in relation to a determined reference is shown in real time, in the main video screen.…”

Sensing Using Light: A Key Area of Sensors

“…Can terms, concepts, methods, effects, approaches, techniques, technologies, etc., so disparate, as mentioned in [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ], all be considered under the same sensing umbrella?…”
