
High-pressure steam sterilization (High-pressure steam sterilization is preferred for the metal
guided brackets)
1. Wear a pair of gloves to prevent infection.
2. Clean the needle-guided bracket thoroughly in accordance with the cleaning procedure before
sterilization.
3. Package the needle-guided bracket in accordance with the sterilization requirements of
surgical instruments.
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.
5. Take out the sterilization package after sterilization and dry it in an oven at 60°C for 20–30
minutes.
6. Keep the sterilization package together with other sterilized surgical instruments in a sterile
item storage area.
7. Check whether the needle-guided bracket has defects such as deformation and rusting before
use. If such defects exist, the bracket has reached the end of its service life. In this case, stop
using it and contact the Mindray service department.
NOTE: 1. Repeated sterilization with liquid sterilant may degrade the safety and performance
of the plastic needle-guided bracket. Please check the needle-guided bracket’s
performance periodically.
2. Needle guided brackets are required to verified before each biopsy. If the verification
fails, it indicates that the needle-guided brackets are out of service life. For details
about needle guided bracket verification, please refer to "13.2.4 Biopsy
Menu/Guideline Verification".
