6. Remove the protective sleeve from the Probe.
•
The Integrated Coaxial Cannula may be removed if further ease of
insertion is desired. If it is removed, discard appropriately. It is
recommended that the Integrated Coaxial Cannula not be reattached to
the Probe to minimize the risk of injury.
7. If necessary, use the Needle Rotation Knob to adjust the position of the Needle
Aperture before introducing the Probe into the incision. To rotate, pull the Needle
Rotation Knob out (See Illustration 5, Step 1). Rotate to desired clock position
(See Illustration 5, Step 2) and release (See Illustration 5, Step 3). The Aperture
Locator indicates the position of the aperture.
Illustration 5:
8. Introduce the Probe through the incision and position the Probe tip in the target
area with the tip past the lesion. Imaging guidance should be used as
appropriate.
•
Keep fingers clear of active Biopsy Button until target site has been
reached.
9. Push the active Biopsy Button on the Holster to acquire a tissue sample. The
biopsy cycle proceeds automatically. A vacuum is created, the inner cutter
cannula of the Probe is retracted, tissue is drawn into the Needle Aperture and
the hollow cutter rotates and translates forward, cutting tissue. When the cutter
reaches the distal end of the Needle Aperture, it will stop moving and use the
vacuum to transport the sample to the Specimen Collection Cup. The Biopsy
Indicator Light continuously illuminates orange and the motor will be audible
during the sampling and tissue collection process. At the end of the biopsy cycle,
the vacuum will turn off and the Biopsy Indicator Light will illuminate solid green.
•
Do not remove the Specimen Collection Cup during tissue acquisition.
•
The biopsy cycle may be interrupted to avoid unnecessary injury or
visualize the location of the aperture via imaging (sonogram).
