Probes and Biopsy 13-13
13.2 Biopsy Guide
1. The person performing biopsy procedures must understand
diagnostic ultrasound thoroughly and have been trained
adequately, otherwise, side effects may be caused to the patient.
2. 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.
3. 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.
4. 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.
5. DO NOT freeze an image while performing biopsy procedure.
6. 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.
7. 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.
8. 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.
9. Adjust the needle mark before the biopsy procedure is performed.
10. 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.
11. When performing the operation concerning biopsy, wear sterile
gloves.
12. Image of the biopsy target and the actual position of the biopsy
needle:
Diagnostic ultrasound systems produce tomographic plane
images with information of a certain thickness in the thickness
