Probes and Biopsy 13-19
13.2 Biopsy Guide
WARNING:
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 direction of the
probe. (That is to say, the information shown in the images consist all
the information scanned in the thickness direction of the probe.) So,
even though the biopsy needle appears to have penetrated the target
