▌ Biopsy Procedure
The system generates a needle guideline through the displayed real-time ultrasound images
to indicate the anticipated path of the needle. You can use this guideline to ensure that the
needle or instrument is following the correct path.
1. Ready the patient according to the procedure appropriate for the examination objectives.
2. Install the sheath and the biopsy kit.
3. Set the system controls for the biopsy procedure. If necessary, apply acoustic gel to the
patient.
4. Begin scanning the patient. Adjust the patient so that the location for examination fits into
the needle guideline on the screen.
5. Install the needle into the needle guide for use. Perform the puncture by sliding the
needle through the groove in the guide until the needle intercepts the target. To keep the
needle securely in the needle guide, press down on the top of the biopsy adapter with
your index finger.
6. When the examination location is reached, take the needle out of the needle guide.
7. Detach the needle guide, adapter and sheath from the probe.
8. Dispose of the components that are not designed for reuse.
▌ Needle Guide Alignment
WARNING
■ The needle used for this alignment verification must not be used for the
actual procedure. Always use a new, sterile needle for each biopsy
procedure.
■ To assist in accurate projection of the needle, use a straight, new needle for
each alignment procedure.
Alignment of the needle guide displayed on the system is for the purpose of verifying
whether the needle and the needle guide are properly installed. This must be done prior to
the biopsy examination. Contact Samsung Medison ‘s servicing department for service.
Reverberation or other tissue artifacts may produce false needle images, which can cause
confusion. Ensure that the needle path is along the guideline, and that you are not using a
false needle image to locate the needle.
1. Attach the biopsy kit.
2. Set the system depth for the procedure to be performed and select the Biopsy menu.
3. Immerse the probe into the water bath, and insert the needle into the needle guide.
4. Confirm that the needle image is on the needle guidelines. If so, the needle guide is
properly aligned.
5. If the needle image is out of the needle guideline, check the needle guide or the probe
adapter.
