INSTRUCTIONS FOR USE
1. Identify the desired target site by endobronchial ultrasound.
2. With the needle retracted into the sheath and the thumbscrew on the
safety ring locked at the 0 cm mark to hold the needle in place, introduce the
ultrasound needle into the accessory channel of the scope (Fig. 5).
Caution: If resistance is encountered on needle introduction, reduce angulation
of the scope until smooth passage is allowed.
3. Advance the device, in small increments, until the Luer lock fitting at the
base of the sliding sheath adjuster meets the Luer fitting of the accessory
channel port.
4. Attach the device to the accessory channel port by rotating the device
handle clockwise until the fittings are connected.
5. Adjust the sheath to the desired position, ensuring that it is visible on the
endoscopic image, emerging from the working channel of the scope. To adjust
length, loosen the thumbscrew lock on the sliding sheath adjuster and slide
until the preferred length is attained. Note: The reference mark for the sheath
length will appear in the sliding sheath adjuster window (Fig. 6). Tighten
the thumbscrew on the sliding sheath adjuster to maintain the preferred
sheath length.
6. While maintaining position of ultrasound scope, set the needle extension
to the desired length by loosening the thumbscrew on the safety ring, and
advancing it until the desired reference mark for needle advancement appears
in the window of the safety ring (Fig. 7). Tighten the thumbscrew to lock the
safety ring in place. Note: The number in the safety lock ring window indicates
the extension of the needle in centimeters. Caution: During needle adjustment
or extension, ensure the device has been attached to the accessory channel of
the scope. Failure to attach the device prior to needle adjustment or extension
may result in damage to the scope.
7. Extend the needle, by advancing the needle handle of the device to the pre-
positioned safety ring, into the target site. Caution: If excessive resistance is
encountered on needle advancement, retract the needle into the sheath with
the thumbscrew locked at the 0 cm mark, reposition the scope and attempt
needle advancement from another angle. Failure to do so may result in needle
breakage, device damage or malfunction.
8. Standard vacuum syringe techniques may be applied for sample collection
(Steps 9-11) or, if desired, other techniques that may or may not incorporate the
use of this stylet may be used.
9. Remove the stylet from the ultrasound needle by gently pulling back on the
plastic hub seated in the Luer fitting of the needle handle. Preserve the stylet
for use if additional sample collection is required later.
10. Attach the Luer lock fitting of the previously prepared syringe securely to
the Luer fitting on the needle handle.
