摘要:
An apparatus, system and method determining a position of an instrument (100) are provided. A sheath (104) is configured to fit within an instrument channel of a medical scope. An optical fiber (112) is disposed within the sheath and a plurality of sensors (106) is integrated in optical fiber. The sensors are configured to measure deflections and bending in the optical fiber. A fixing mechanism (140) is sized to fit within the instrument channel in a first state and fixes the sheath within the instrument channel in a second state such that the fixing mechanism anchors the sheath and the optical fiber so that the deflections and bending in the optical fiber are employed with a pre-procedural volumetric image to determine a position of the instrument.
