Optical surgical navigation device tracking system spatial register, single-use
Definition
A component of an optical surgical navigation device tracking system intended to localize/track the position/movement of a patient, fiducial marker and/or an optically navigated surgical instrument (e.g., a stereotactic surgery system probe, dental drill), and/or register surgical instrument size (e.g., length, width), in association with a computer assisted surgery (CAS). It may be attached to the patient, fiducial marker or surgical instrument, and may contain features (e.g., reflective spheres, contrast patterns) detectable by a tracking camera [e.g., infrared (IR) light camera]; it is typically made of metal. This is a single-use device.
