摘要：
An apparatus comprises an instrument including an elongated shaft. The apparatus also comprises a first shape sensor including an elongated optical fiber extending within the elongated shaft at a first radial distance from the neutral axis. The apparatus also comprises a twist resistant feature configured to reduce twisting of the elongated optical fiber relative to the elongated shaft while permitting axial translation of the elongated optical fiber within the elongated shaft.
