1. A medical instrument system for inserting a medical instrument within a patient body, the system comprising:
the medical instrument comprising an optical fiber having one or more core fibers;
a stiffening stylet;
an adjustment mechanism including a proximal collar, a distal collar, and a pair of hinged arms, wherein the proximal collar is coupled to the stiffening stylet, wherein:
actuation of the adjustment mechanism moves the proximal collar in (i) a proximal direction which moves the stiffening stylet in the proximal direction relative to a distal tip of the medical instrument, or (ii) a distal direction which moves the stiffening stylet in the distal direction relative to the distal tip of the medical instrument; and
a console including one or more processors and a non-transitory computer-readable medium having stored thereon logic, when executed by the one or more processors, causes operations including:
providing an incident light signal to the optical fiber,
receiving reflected light signals of different spectral widths of the incident light signal by the optical fiber,
processing the reflected light signals associated with the optical fiber, and
determining a location of the distal tip of the medical instrument within the patient body,
wherein the medical instrument is configured to be manipulated in order to direct the distal tip in a particular direction.
