17.2 Biopsy Guide
WARNING
• The person performing biopsy procedures must understand diagnostic
ultrasound thoroughly and have been trained adequately, otherwise, side
effects may be caused to the patient.
• In situations listed below, the biopsy needle may fail to penetrate the target.
The incorrect biopsy may cause various side effects in the patient.
– Use a needle-guided bracket other than that provided.
– Mount the needle-guided bracket incorrectly.
– Use a biopsy needle that is unsuitable for the type of biopsy being
performed.
– Use a biopsy needle that is unsuitable for the needle guide.
• Before and after a biopsy procedure is performed, confirm that the needle-
guided bracket is normal. Manually confirm that the parts of the needle-
guided bracket do not slip off or move from their proper positions. If the
needle-guided bracket is used when parts are not securely and correctly
installed, the patient may be injured. If an abnormality is found on the
needle-guided bracket, immediately stop using it and contact MINDRAY
Customer Service Department or sales representative.
• DO NOT use a needle-guided bracket when scanning is performed. The
needle may advance in an incorrect direction and possibly injure the
patient.
Never perform a biopsy during image scanning.
• DO NOT freeze an image while performing biopsy procedure.
• During biopsy procedures, the needle may deviate from the desired course
due to the tissue characteristics or the type of needle. In particular, needles
of small diameters may deviate to a greater degree.
• Disinfect the probe and sterilize needle-guided bracket before and after
each ultrasound-guided biopsy procedure is performed. Fail to do so may
cause the probe and the needle-guided bracket become sources of
infection.
• The needle mark displayed on the ultrasound image does not indicate the
actual position of the biopsy needle. Therefore, it should only be used as a
reference. Always monitor the relative positions of the biopsy needle during
the procedures.
• Adjust the needle mark before the biopsy procedure is performed.
• When performing biopsy procedures, use only sterile ultrasound gel that is
certified to be safe. And manage the ultrasound gel properly to ensure that
it does not become a source of infection.
• When performing the operation concerning biopsy, wear sterile gloves.
