1. WARNINGS: Burs are not sterile upon receipt and must be sterilised before use in accordance with the following instructions. Burs can be damaged by alkaline and acidic detergents. Always use a pH neutral detergent or solution. Do not exceed 140°C. Remove all packaging prior to cleaning and sterilisation. Contaminated burs should be handled with gloves and eye protection should be used.

2. Limitations on Reprocessing: Repeated processing has minimal effect on these burs. End of life is normally determined by wear and damage due to use. NOTE: Steel Burs are single use only and cannot be reprocessed. See Inspection.

Instructions

3. Point of Use: Remove from packaging. Diamond/Tungsten Carbide Burs: Remove all excess soil with disposable cloth paper wipe.

4. Containment and Transportation: Protect delicate or fine burs from damage. Burs left standing wet may stain or corrode. Diamond/Tungsten Carbide Burs: Burs should be reprocessed as soon as is reasonably practical following use.

5. Preparation for Cleaning: No specific requirements.

6. Automatic Cleaning: Use only validated washing machines (HTM 2030: UK only) and validated cleaning agents suitable for both devices and washing machine. Follow instructions issued by both the equipment and cleaning agent manufacturers. When unloading, inspect for complete removal of visible soil. If necessary, repeat cycle, or use manual cleaning before repeating cycle.

7. Maintenance: Discard damaged burs.

8. Inspection and Function Testing: All Burs: Visually inspect to ensure all contamination has been removed. Check for damage and wear. Cutting edges should be free of defects. Discard damaged or corroded burs. Check burs with long, slender features for distortion. Where burs form part of a larger assembly, check assembly with mating components. There may be evidence of discolouration or dulling after sterilisation: this is normal and will not affect performance.

9. Drying: Dry using paper towelling or dry heat not exceeding 140°C.

10. Packaging for Sterilisation: The UK Dept. of Health recommends that validated, pre-vacuum autoclaves are used for sterilising wrapped burs. Autoclaves drawing only a post-sterilisation vacuum for drying purposes are not suitable for processing wrapped burs. Burs may be loaded into dedicated instrument trays or general-purpose sterilisation trays. Ensure that cutting edges are protected.

11. Sterilisation: Use only validated vacuum autoclaves (Refer to HTM2010: UK only). Do not exceed 140°C.

* Minimum holding time when nominal operating temperature and pressure have been reached.

12. Storage: Avoid contamination.

13. Additional Information: When sterilising multiple burs in one autoclave cycle, ensure that the manufacturers stated maximum load is not exceeded. Validated ultrasonic baths may be used with validated cleaning agents. Follow instructions for use issued by both the equipment and cleaning agent manufacturers.

These instructions have been validated by the manufacturer as being capable of preparing a device for re-use. It remains the responsibility of the reprocessor to ensure that the reprocessing has actually achieved the desired result. This normally requires validation and routine monitoring of the process. Any deviation by the reprocessor from these instructions should be properly evaluated for effectiveness and potential adverse effects.
