Reusable biopsy needle guides
Caution
Cleaning and sterilization of reusable biopsy guides (for disposable biopsy guides, please refer
to enclosed manuals):
After each use, remove needle guide from transducer. Remove visible contaminants from
needle guide surface thoroughly, using a small, soft instrument brush. Take special care of all
narrow areas and tubes. Keep needle guide from drying out until complete cleaning can be
accomplished. After that, soak needle guide for minimum of five minutes in neutral pH, low
foamingenzymatic detergent.
While immersed, use instrument brush to remove trapped contaminants from surfaces, holes
and tubes. If visible contaminants cannot be easily removed, repeat soaking procedure for an
additional five minutes. Remove needle guide from cleaning solution and remove any
remaining residue with dry wipe. Follow cleaning solution manufacturer's instructions for use
and recommendations for concentration.
Sterilization for reusable biopsy needle guides:
