Abstract
An arc-detection system for detecting an arc during an electrocautery surgical procedure may comprise a camera portion and an image processing controller portion. The camera portion may be sized for minimally invasive penetration into a patient's body. The camera portion may comprise a wide-angle lens having a field of view wider than 45 degrees and wider than a field of view of a conventional endoscopic camera system. The image processing controller portion may be configured to monitor images captured by the camera portion and configured to detect thermal changes to tissue at the surgical site.
