guide (or guiding block).
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. Clean and disinfect the transducer, clean and sterilize the
the needle-guided bracket before and after each
ultrasound-guided biopsy procedure is performed. Fail to
do so may cause the transducer 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 transducer. (That is to say,
the information shown in the images consist all the
information scanned in the thickness direction of the
transducer.) So, even though the biopsy needle appears
to have penetrated the target object in the image, it may
not actually have done so. When the target for biopsy is
small, dispersion of the ultrasound beam may lead to
image deviate from the actual position. Pay attention to
this.
