An electrically-powered component of an intraoperative parathyroid detection system designed to aid surgeons in recognizing parathyroid tissue during open surgical thyroidectomies and parathyroidectomies using near-infrared (NIR) light and auto-fluorescence. It consists of a console with display and controls. The NIR light is emitted, and the florescence measured, using a single-use invasive probe (not included).
