    摘要: A medical instrument system includes a controller and a guide instrument coupled to an instrument driver, the instrument driver configured to manipulate a distal end portion of the guide instrument in response to control signals generated by the controller. A force sensor is associated with the guide instrument or with a working instrument carried by the guide instrument, and generates force signals responsive to a force applied to a respective distal end portion of the guide instrument or working instrument. A position determining system generates position data indicative of a position of the respective guide or working instrument distal end portion associated with the force sensor, and a processor operatively coupled to the force sensor and position determining system processes respective force signals and position data to generate and display a geometric rendering of an internal body tissue surface based on sensed forces applied to the respective instrument distal end portion as the guide instrument is maneuvered within an interior region of a body containing the body surface.
