13 Probes and Biopsy
Operator’s Manual 13 - 53
• It is extremely important that when using the adjustable angle biopsy
guides, the angle displayed on the screen matches the angle set on the
guide, otherwise the needle will not follow the displayed guide zone and
this could result in repeated biopsies or patient injury.
Perform the following procedure:
1. Select the correct needle-guided bracket and needle and install them properly.
2. Enter the biopsy.
If the current probe has no corresponding bracket, or the image is frozen and the guide line was
hidden before the image was frozen, then you cannot enter the Biopsy menu.
3. Select the bracket and guide line according to the actual situation.
Select to enter Biopsy Verify menu to fine tune the guide line if needed.
4. If available, use iNeedle function to help enhance the needle visualization when the needle
display is not clear.
iNeedle is an option.
a. Select [iNeedle].
The parameters that can be adjusted appear on the menu:
[B/iNeedle]: select to display B image and iNeedle image synchronously.
[Needle Dir.]: select to adjust the needle direction display according to actual direction of
needle insertion. The iNeedle affecting region changes correspondingly.
b. Select [iNeedle] again to exit.
5. Scan to locate the target. Center the target in the electronic guidezone path.
6. Direct the needle into the area of interest for specimen.
7. After extracting the biopsy sample is complete, gently remove the probe from the body.
8. Exit the Biopsy menu.
9. Disassemble the items and properly dispose of these items as required.
13.2.5 Clean and Sterilize the Needle-Guided Bracket
• Needle-guided brackets whose name starts with NGB are reusable, and
need thorough cleaning and sterilization before and after each biopsy.
• Follow local regulations when selecting and using the disinfectant.
• Repeated sterilization may degrade the safety and performance of the
needle-guided bracket. Before use, please check whether the needle-
guided bracket has defects such as deformation and rusting. If such
defects exist, the bracket has reached the end of its service life. In this
case, stop using it and contact the Mindray service department.
• It is recommended to use immersion sterilization for plastic needle-guided
brackets and high-pressure steam sterilization for metal needle-guided
brackets.
