Intended Use of the Navigated Instrument The trackers are intended for patient tracking and for use with the Stryker® Navigation System. The trackers emit signals which are received by the camera. The system uses the signals to calculate the spatial relationship between the patient and the surgical instrument. The position of the instrument in relationship to the patient's anatomy is displayed on the monitor. Moreover, each patient tracker may be used to validate a pointer or navigated instrument. The Patient Tracker, Blue REF 6007‑010‑000 and the Patient Tracker, Green REF 6007‑005‑000 are intended to be used with the Stryker Navigation System - Hip Modules. The Tibial / Pelvic Tracker REF 6003‑005‑000 and the Femoral Tracker REF 6003‑010‑000 are intended to be used with the Stryker Navigation System - Knee Modules.

• This equipment is not suitable for use in the presence of flammable anesthetic mixtures with air, oxygen or nitrous oxide. • During surgery, if fluids such as saline solutions enter the battery holder, the electronics can fail and communication with the system will cease. • During surgery, keep the LEDs clean and out of contact with liquids at all times. • Excessive infrared radiation from external sources can influence localization of the instrument by the navigation system. Refer to the Navigation System Camera Instructions for Use. • DO NOT service the instrument. It does not contain any parts the user can service. If service is required, contact your Stryker Navigation sales representative. • Prior to and during the surgical procedure, regularly verify that the instrument is firmly attached to the anchoring device. If the tracker moves relative to the patient, the navigation is inaccurate. • Use this manual with the instructions for use supplied with the anchoring device for further warning or caution notes and detailed anchoring instructions. • Location and movement of the instrument as it relates to the patient tracking system is displayed on the navigation system monitor. • After patient registration, any change in the position of the patient tracking system in relationship to the patient compromises navigation accuracy. Therefore, the patient must be re-registered. • Upon any suspected movement of the trackers, perform a landmark check using verification points or movement checkpoints to ensure accuracy, depending on your software application. If the tracker is suspected of having moved, replacement of the tracker fixation and reacquisition of the registration points must be performed. Alternatively, the navigation must be abandoned and conventional techniques used.
