A VacLok aspiration syringe with a 20 ml fill volume

An endoscopic ultrasound fine needle biopsy (FNB) system with a crown-cut needle tip for core-tissue sampling.

In which cases?

  • Pancreatic masses where immunohistochemistry and molecular testing decide the treatment.
  • Submucosal and extramural lesions where tissue architecture has to be assessed.
  • Primary diagnosis and staging of malignant and potentially malignant disease.
  • Cases where the unit wants to keep the number of passes low, with macroscopic on-site evaluation.

What makes it different?

  • Three-point crown cut tip; the manufacturer states the bevel is shallow and puncture force is lower.
  • More tissue per pass than a standard aspiration needle three microcores against two and about six times the total tissue area, 2.74 mm2 against 0.44 mm2 (Kovacevic et al., randomised study, Endosc Ultrasound 2023, n=64).
  • The sheath and the needle length are set and locked on the same Twist-Lock ring, with one hand.
  • A specially treated needle surface, which the manufacturer states gives better needle visibility under ultrasound.

Frequently asked questions

Which gauge goes with which sheath diameter?

The models table pairs them: the 19G needle is 1.1 mm on a 2.1 mm sheath, and the 22G and the 25G needle are 0.7 and 0.5 mm on a 1.8 mm sheath. The sheath diameter is what has to pass the working channel of the echoendoscope, so it is the number to check before the case.

How is the needle length set?

On the handle. The needle length adjustment is 0 to 8.5 cm, set and locked on the Twist-Lock ring with one hand, and the same ring sets the sheath length.
