13-28 Probes and Biopsy
Failure to match the guide zone displayed to the
guide may cause the needle to track a path outside
the zone.
It is extremely important that when using the
adjustable angle biopsy guides, the angle displayed
on the screen matches the angle set on the guide,
otherwise the needle will not follow the displayed
guide zone and this could result in repeated
biopsies or patient injury.

2. Confirm that the needle-guided bracket is free from damage, deformation, stripping,
malfunction, loose or missing parts.

13.2.3.2 Installing the Needle-Guided Bracket
NGB-004
1. Put the sterile probe sheath on.
2. Open the retaining clamp, align the needle-guided bracket with the probe to align the locating
bulge on the needle guide with the locating grooves on the probe, then turn the retaining
clamp to align it with the probe (see the figure below).
3. When the retaining clamp is turned to the correct position, the locking nut will lock the retaining
clamp and the needle-guided bracket is then mounted in the correct position.
