• When the probe is sent to MINDRAY Customer Service Department or sales representative for
repair, be sure to disinfect it and keep it in the carrying case to prevent infection.
16.2 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.
• 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.
• Disposable brackets are packaged sterile and are single-use only, and the
method of sterilization is irradiation. Do not use if the sterile packaging is
open or broken, and do not reuse or resterilize the disposable brackets.
• 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
