WARNING
If the needle guide is detached from the transducer during interventional procedures,
cover the transducer with a new transducer cover before reattaching the needle guide..
WARNING
It is essential for the patient's safety that only the correct needle guide, as described in this
guide, are used. Never use unauthorized combinations of transducers and needle guide or
other manufacturers needle guide.
Before beginning a puncture or biopsy procedure, always check that the type number of
the transducer and the type number or description of the needle guide 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.
WARNING
The 8815 transducer cannot monitor the first 1.2-1.5 cm of the puncture line (the blind
spot, see Figure 6). Extra care should be taken during insertion until the needle tip echo
can be seen on the image.
Cover the transducer with a sterile transducer cover.
If the transducer cover is damaged when attaching the needle guide, 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.
Press the scanner Puncture or Biopsy control button to superimpose a puncture
line on the scan image.
If more than one puncture line is available, refer to the applicable scanner user guide
for instructions on how to change which one appears.
Move the transducer until the puncture line transects the target. Insert the needle
and monitor it as it moves along the puncture line to the target. The needle tip
echo will be seen as a bright dot on the screen.
