SYSTEM AND METHOD FOR MINIMIZING FIBER TWIST IN OPTICAL SHAPE SENSING ENABLED DEVICES

摘要

A fiber twist reduction system for optical shape sensing enabled instruments includes a rotatable launch fixture (12) configured to hold an optical fiber (28). An optical shape sensing enabled device (26) includes the optical fiber disposed therein. A rotation mechanism (14) is configured to rotate the fiber in response to a twist of the fiber to reduce accumulated twist along its length.
