Performing Puncture and Biopsy
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.
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 mon-
itor 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.
To remove the puncture line from the scan image, refer to the applicable scanner user guide
for instructions.
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 cor-
rected.
WARNING
If the needle guide is detached from the transducer during interventional procedures, cover
the transducer with a new transducer cover.
WARNING
When performing a biopsy, always make sure that the needle is fully drawn back inside the
needle guide before moving the probe.
