Abstract
An articulating, steerable surgical probe includes an elongated, flexible transfer tube adapted for insertion into a surgical region for endoscopic laryngeal laser surgery. A lumen is defined by an interior of the transfer tube, and a laser fiber extends through the lumen for delivering a therapeutic laser signal to a distal end of the laser fiber. An articulating tip at the distal end of the transfer tube is responsive to articulating forces from a retractable tether for directing the treatment probe in a direction of the articulation, and a linkage to the tether from a control module effects controlled retraction of the tether for articulating the tip towards a surgical target, such that the articulating tip imposing a bend radius based on a signal loss through the laser fiber.
