Array Positioning
The system recognizes an instrument by the geometrical arrangement of the marker spheres on
its tracking array. For the system to properly identify an instrument, the camera must have a clear
view of its marker spheres at all times.
For the best recognition of the array, position the array perpendicular to the plane through the
centers of all marker spheres.
Possible Complications
Use of some Brainlab products requires an additional incision to be made. Therefore, the following
complications may occur: infection, local pain, bleeding, lesion of blood vessels or nerves, bone
fracture or thrombosis.
Creutzfeldt-Jakob Contamination
Warning
Do not use Brainlab instrumentation on patients suspected of having Creutzfeldt-Jakob
disease (CJD or vCJD).
MR Safety
Unless otherwise noted, instruments are MR unsafe.
Sterilization
If a sterile instrument or any of its components is inadvertently removed from the sterile field, or
comes into contact with an unsterile object during unpacking or clinical use, it must be sterilized
again.
Do not resterilize or reuse disposable instruments, as this could affect navigation accuracy, posing
a risk to the patient. They must be disposed of after each use.
Warning
Unless otherwise indicated, instruments must be sterilized before use. Detailed information
about reprocessing procedures, parameters and cleaning detergents are available in your
Cleaning, Disinfection & Sterilization Guide.
