13-46 Probes and Biopsy
3 Prepare a cleaning solvent (enzymatic or neutral pH detergent, e.g., liquinox, MetriZyme) by using
distilled or softened water in accordance with the operator's manual provided by the manufacturer.
4 Detach all the detachable parts of the needle-guided bracket and immerse the detached parts fully
in the cleaning solvent for at least 1 minute or a period specified by the manufacturer.
5 Immerse the needle-guided bracket and all its parts fully in the cleaning solvent. Wipe and wash
the surface and connecting parts of the needle-guided bracket gently by using a soft brush until no
dirt is visible. Place the needle-guided bracket inside an ultrasonic cleaner and perform ultrasonic
cleaning for 3–5 minutes.
6 Rinse the needle-guided bracket thoroughly by using a large amount of distilled or softened water
(about 2 gallons) at room temperature for about 30s to remove the residual dirt and cleaning
solvent. Repeat the operation twice.
7 Wipe away the water on the needle-guided bracket by using a piece of disposable lint-free soft
cloth.
8 Inspect the needle-guided bracket. If visible dirt still exists, repeat the preceding steps to wash the
bracket until it is all clean.
9 Check whether the needle-guided bracket has defects such as deformation and rusting. 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.
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 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.
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 may degrade the safety and performance of the 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.
13.2.9 Storage and Transportation
1. Don not use the carrying case for storing the needle-guided bracket. If the carrying case is used for
storage, it may become a source of infection.
2. Between examinations, keep the needle-guided bracket in a sterile environment.
3. When the needle-guided bracket is sent to your MINDRAY representative for repair, be sure to
disinfect or sterilize it and keep it in the carrying case to prevent infection.
4. Sterilize the carrying case as necessary.
5. Store or transport the needle-guided brackets under the following ambient conditions:
Ambient temperature: -20°C to 55°C
