ROBOTIC SURGICAL INSTRUMENT AND METHODS USING BRAGG FIBER SENSORS |
摘要 |
A positionable medical instrument assembly, e.g., a robotic instrument driver configured to maneuver an elongate medical instrument, includes a first member coupled to a second member by a movable joint, with a Bragg fiber sensor coupled to the first and second members, such that relative movement of the first and second members about the movable joint causes a bending of at least a portion of the Bragg fiber sensor. The Bragg fiber sensor has a proximal end operatively coupled to a controller configured to receive signals from the Bragg fiber sensor indicative of a bending thereof, the controller configured to analyze the signals to determine a relative position of the first and second members about the movable joint. |
