b.
Modify the angle of the needle (up or down) to place the Point of Intersection Circle in the center of the
intended target structure. A steeper insertion angle may be necessary for deep structures while a shallow
angle may be appropriate for superficial anatomy
c.
While maintaining the needle angle, insert the Pinpoint™ GT Safety Introducer Needle into the skin. Refer to
the Pinpoint™ GT Safety Introducer Needle Instructions for Use for more information
d.
To maintain accuracy, use a
‘light touch,’
(defined as minimal stress, force, or pressure on the needle during
insertion)
Note:
Once the needle enters the skin, it may be helpful to release pressure on the needle hub to assess
Pinpoint™ GT Needle Technology System alignment with the structure of interest.
Caution:
During insertion, use a light touch to prevent needle deflection and/or bending. Needle deflection and/or
needle bending may reduce needle tracking accuracy.
Caution:
To ensure accuracy, do not apply force or pressure that may leverage the needle. This may result in
needle deflection, bending or altering needle trajectory.
e.
Without leveraging the needle, proceed with insertion – watch needle advancement onscreen. The yellow line
represents the needle shaft and tip. The violet circle represents where the needle will intersect the ultrasound
plane
f.
During advancement, maintain the Point of Intersection Circle in the center of the intended target structure
g.
Once the Pinpoint™ GT Safety Introducer Needle tip intersects the ultrasound beam, the Point of Intersection
Circle will change from violet to green. When the Point of Intersection Circle changes to green, it means the
introducer needle has intersected the plane of the ultrasound beam. It does
NOT
necessarily mean insertion
has been successful or the structure of the interest has been reached
h.
If the needle passes through the Point of Intersection Circle, the circle changes color from violet to green and
the portion of the needle that lies beyond the Point of Intersection Circle changes color from yellow to violet.
Note:
When the virtual needle image changes from yellow to violet, it does
NOT
necessarily mean that you
have advanced your needle beyond the target structure, it means the needle is beyond the ultrasound
plane.
