7.8 Performing a Biopsy and Acquiring Real-time Images
Perform all steps per standard interventional technique.
1. Identify the targeted area and prepare the site as required.
2. Assemble the biopsy device and advance it to the desired coordinates provided by
the imaging system.
Warning:
If there is a problem advancing the needle into the breast, check the
sharpness of the trocar needle tip. Replace the needle if necessary.
Note
X-ray is enabled when the drawer is closed. If the drawer is opened during an exposure,
the exposure ends automatically.
3. Confirm that the system is ready to perform a biopsy procedure.
• Confirm that the system is free of any error messages.
• Confirm that all patient entry steps are complete and that the Procedure screen is
displayed on the Imaging display.
• Confirm the aperture size and that the biopsy device is armed.
• Confirm that the Key switch is in the unlocked position.
• Confirm that the system is in Biopsy mode.
4. Fire the biopsy device by pressing and holding the Fire button on the remote control
for at least 2 seconds.
5. Administer anesthetic (optional).
• To initiate automatic delivery of anesthetic: Attach a 10 cc needleless syringe of
anesthetic to the Y-valve. Inject 1–2 cc of anesthetic via the needleless syringe.
• To manually administer anesthetic to the area of interest before tissue
acquisition: (the biopsy device has been fired, the footswitch has not been
depressed) Manually inject anesthetic via syringe and rotate the thumbwheel to
allow 360 degrees of access.
• To manually administer anesthetic to the area of interest during tissue
acquisition: (the biopsy device has been fired, the footswitch has been depressed)
place the system in Standby mode to close the aperture. Manually inject
anesthetic via syringe and rotate the thumbwheel to allow 360 degrees of access.
Once complete, return the system to Biopsy mode to continue tissue acquisition.
Note
The device does not allow the Y-valve injection when the device is in the armed (pre-
fire) position.
