Optical surgical navigation device tracking system suction cannula
Definition
An atraumatic, invasive, hand-operated, rigid/semi-rigid tubular component of an optical surgical navigation device tracking system designed as a conduit for aspiration of body cavities or surgical sites to facilitate observation and/or to clear airway obstruction, typically during a cranial and/or ENT procedure, in association with computer assisted surgery (CAS); it is not intended for surgical irrigation. Also referred to as a suction tube or tip, it incorporates a handle with features (e.g., reflective spheres, contrast patterns) detectable by a tracking camera [e.g., infrared (IR) light camera]; it does not include a light source or fibreoptic bundle. This is a single-use device.
