Indications for Use
The 8824 is a simultaneous biplane transducer for ultrasound-guided interventional
procedures.
Needle guide UA1337 provides guidance for needles or other interventional devices
during an ultrasound-guided procedure. It positions the needle relative to the
transducer, so that the needle image is in a specified position in the ultrasound image
during procedures that require precise needle placement or biopsy.
WARNING
Do not use the transducer for applications where it may come in direct conductive contact
with the patient’s heart.
FDA WARNING for the United States of America
8824 is not for fetal use.
Scanning Planes
The transducer contains two convex arrays in the shape of a T. Each array has a single
scanning plane and the two scanning planes intersect orthogonally, see Fig. 2 The
two scanning planes can be viewed separately or simultaneously, thus giving a better
orientation when viewing suspicious lesions.
8824 User Guide (BB1823-C)
Introduction

Simultaneous Biplane Scanning
The transducer can transmit transverse (T) and sagittal (S) images simultaneously.
When you press the scanner’s Split button, simultaneous live transmission is
automatically activated. On the screen, this is indicated by a green dot in front of the
Simultan button.
Click on Simultan to toggle simultaneous live transmission on or off. Alternatively,
a long press on the scanner’s Split button turns simultaneous live transmission off.
When simultaneous transmission is off, you can change which plane is active and
which is frozen by pressing the Split button or by placing the cursor on the image
you want to be active and pressing the Select button.

Performing Puncture and Biopsy
WARNING
It is essential for the patient’s safety that only the correct puncture attachments, as
described in this guide, are used. Never use unauthorized combinations of transducers
and puncture attachments or other manufacturers puncture attachments.
Before beginning a puncture or biopsy procedure, always check that the type number of
the transducer and the type number or description of the puncture attachment match
exactly those displayed on the scanner monitor.
WARNING
The puncture line on the scan image is an indication of the expected needle path. The
needle tip echo should be monitored at all times so any deviation from the desired path
can be corrected. You must take extra care when taking a free-angle biopsy because the
expected needle path is not shown.
Cover the transducer with a sterile transducer cover.
If the transducer cover is damaged when attaching the puncture attachment, replace
it with a new cover.
Note: Sterile, disposable sheaths are recommended for intraoperative use; and in the
U.S.A. it is recommended that probe sheaths have been market-cleared. In Canada,
use only licensed probe sheaths.
See the Product Data sheet for a list of available transducer covers.
