APPARATUS AND METHODS FOR FIBER INTEGRATION AND REGISTRATION

摘要

Systems and methods for integrating and/or registering a shape sensing fiber in or to various instruments are described herein. Registration fixtures and registration techniques for matching the coordinate system of a fiber to the coordinate system of an elongate instrument or other device are provided. Various systems and methods for integrating a shape sensing fiber into an elongate instrument or other device are also described herein.

1. A system, comprising:
an elongate instrument having a proximal end, a distal end, and at least one lumen defined therein; a shape sensing fiber having a first portion and a second portion, wherein at least the first portion of the fiber is positioned within the lumen of the elongate instrument; and an anchor slide fixed to the second portion of the fiber at a proximal location, wherein the anchor slide fixes the proximal location of the fiber to the elongate instrument or a structure associated with the elongate member in one or more degrees of freedom, and wherein the anchor slide is configured to serve as a known location for matching a coordinate system of the fiber to a coordinate system of the elongate instrument or other structure as the fiber slides relative to the lumen of the elongate instrument.
