4. Immerse the needle-guided bracket fully in the sterilant and shake the bracket appropriately to
remove any bubbles on the surface. Use a syringe to draw an appropriate amount of sterilant
and inject the sterilant into the hole to remove the bubbles inside the hole if necessary.
For details about the immersion duration, see the operator’s manual provided by the
manufacturer.
5. After sterilization, wash the needle-guided bracket thoroughly by using a large amount of
sterile distilled water (about 2 gallons) at room temperature for about 30s to remove the
residual sterilant. Repeat the operation twice.
6. Dry the needle-guided bracket by using a piece of sterile disposable lint-free soft cloth.
7. Store the needle-guided bracket in a cool, clean and dry environment.
High-pressure steam sterilization
High-pressure steam sterilization is preferred for the metal guided brackets. And the sterilizer and
accessories should be cleared by FDA for the intended sterilization cycle.
Perform the following procedure:
1. Wear a pair of gloves to prevent infection.
2. Clean thoroughly in accordance with the cleaning procedure before sterilization.
3. Package the needle-guided bracket in accordance with the sterilization requirements of
surgical instruments using the sterilization wrap or pouch cleared by FDA.
4. Place the packaged needle-guided bracket inside a high-temperature steam sterilizer and
perform sterilization. The sterilization parameters are 121 °C and 30 minutes for a gravity
displacement steam sterilizer and are 132 °C and 4 minutes for a dynamic-air-removal steam
sterilizer.
5. Take out the sterilization package after sterilization and dry it in an oven at 60 °C for 20
minutes to 30 minutes.
Keep the sterilization package together with other sterilized surgical instruments in a sterile
item storage area.
