1. A lighted device for use in a surgical procedure, the lighted device comprising:
an elongate member having a distal end for inserting into an operative field of a patient and having a proximal end; and
a handle coupled to the proximal end of the elongate member, the handle having a larger exterior diameter than an exterior diameter of the elongate member; and
a plurality of light sources disposed along the elongate member and configured to emit light in a first wavelength range and a second wavelength range, wherein the plurality of light sources is disposed along at least 50% of the elongated member wherein:
the light emitted by the plurality of light sources in the first wavelength range is able to transmit through one or more first tissues of the patient but unable to transmit through one or more second tissues of the patient;
the light emitted by the plurality of light sources in the second wavelength range is able to transmit through both the one or more first tissues and the one or more second tissues of the patient; and
each respective light source in at least a subset of the plurality of light sources is located at a corresponding distance in a plurality of distances relative to the distal end of the elongate member and adjacent light sources in at least the subset of the plurality of light sources are spaced apart along a length direction of the elongated member at a predetermined interval of between 0.5 cm and 5 cm, thereby allowing a user of the lighted device to locate light sources on the elongate member in the operative field of the patient and use the elongated member for one or more intraoperative measurements by detecting light emitted by at least the subset of the plurality of light sources in the first and second wavelength ranges and transmitted through the one or more first tissues of the patient, the one or more second tissues of the patient or both and to use the elongated member and the located light sources on the elongated member in the operative field of the patient as a ruler for one or more intraoperative measurements.
