INSTRUCTIONS FOR USE
1. Identify the desired targeted site by endoscopic ultrasound.
2. With the needle retracted into the sheath and the thumbscrew on the safety
ring locked to hold the needle in place, introduce the ultrasound needle into
the accessory channel of the endoscope. (See Fig. 6)
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 endoscopes accessory channel port by rotating the
device handle clockwise until the fittings are connected.
5. With the endoscope and device straight, advance the needle to the desired
length by loosening the thumbscrew on the safety ring, and advancing it until
the desired reference mark for the needle advancement appears in the window
of the safety ring. (See 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
endoscope. Failure to attach the device prior to needle adjustment or extension
may result in damage to the endoscope.
6. While maintaining the position of the endoscope, extend the needle by
advancing the needle handle of the device to the pre-positioned safety ring.
7. Advance the needle into the lesion.
8. Remove the stylet of the ultrasound needle by gently pulling back on the
plastic hub seated in the metal fitting of the needle handle. Preserve the stylet
for use if additional cell collection is desired later.
9. Attach the Luer lock fitting of the previously prepared syringe securely into
the fitting on the needle handle.
10. Turn the stopcock to the "open" position aligned with the syringe, allowing
the negative pressure in the syringe to aspirate cells. Gently move the needle
handle, in small increments, back and forth within the biopsy site. Note: Do not
remove the needle from the biopsy site during cell collection.
11. Upon completion of cell collection, retract the needle completely into the
sheath by pulling back on the needle handle and lock the thumbscrew on the
safety ring to hold the needle in place.
12. Disconnect the Luer lock fitting of the device from the accessory channel
port, by rotating the device handle counter clockwise, and withdraw the entire
device from the endoscope.
13. Exchange the locking syringe for an empty syringe and attach the new
syringe to the Luer lock fitting on the needle handle. Unlock the thumbscrew
on the safety ring and extend the needle.
14. Push in the syringe plunger to expel aspirate specimen, then prepare per
institutional guidelines.
