Stereotactic Headring

Handling and Storage
Store the headring at the same place as the other stereotactic equipment. Often, a transportable
instrument cart is suitable for such purposes. Store the sterilized fixation pins in the sterilization
tray.
The Stereotactic Headring components are precise mechanical parts. Even minor damage
to any of these parts may render the entire apparatus inoperable. Do not use the equipment
if it is any way warped, scratched, damaged, or any of the parts are loose. The equipment
must be checked and tested for proper functionality prior to each treatment.
Headring: Cleaning and Disinfection
• Clean the headring periodically using a soft and dry cloth
• The headring should additionally be cleaned with an enzymatic cleaning agent (e.g., from Dr.
Weigert), followed by rinsing in doubly distilled and, preferably, sterile water following any
procedure or contact with biological substances
• You may only use an enzymatic cleaning detergent to clean the headring. You may not use an
alkaline cleaning detergent or an ultrasonic cleaner to clean the headring
• Stains may be removed using a slightly moistened cloth
• Do not use sharp objects or rough materials to remove residue, especially near threaded
surfaces
• Once cleaned, the headring should be thoroughly air-dried or dried using lint-free materials
Posts and Fixation Pins: Cleaning and Disinfection
Automatic cleaning and disinfection can be used for the posts and the fixation pins. See page 95
Headring Post Sterilization
The headring posts can be sterilized using:
• Neutral Steam Sterilization (Page 97)
• Low Temperature Plasma Sterilization (Page 98)
If steam sterilization is used regularly, the threads in the headring posts can be damaged.
Check the posts regularly to ensure that the threads in particular are in good condition.
Replace the posts immediately if chipping or perpendicular fibers are visible, if the CFRP
material is damaged, or if the headpins are difficult to screw in.
The sterilization process causes gradual deterioration of the material. Up to 100 re-
processing cycles are possible using one of the specified sterilization methods listed
above.
Fixation Pin Sterilization
The fixation pins must be sterilized after use. Clean, disinfect, and dry the fixation pins effectively,
then transfer them to the sterilization tray prior to sterilization.
Wrap the Sterilization Tray in suitable single-use sterilization packaging in accordance with EN
868 and AAMI/ISO 11607 (e.g., paper/foil sterilization bags).
Sterilize the fixation pins using:
• Neutral Steam Sterilization (Page 97)
• Low Temperature Plasma Sterilization (Page 98)
