EBUS-TBNA Aspiration Needles

EBUS-TBNA

Contents start

EBUS-TBNA is used in diagnostic or cancer staging procedure on patients with lung tumours, mediastinal lesions, or enlarged lymph nodes in or close to the mediastinum. The EBUS-TBNA procedure is a reliable, safe and less invasive procedure than mediastinoscopy.
Olympus is unique in offering a 22G and 21G EBUS-TBNA needle for a wider field of application.

Single-use EBUS-TBNA aspiration needle - ViziShot

Single-use aspiration needles are available in 21G and 22G with excellent puncture capability under ultrasound view. Both needles are equipped with a dimpled echogenic design that improves visibility on ultrasound images to enable a precise puncture. To ensure a safe procedure, a fast locking needle adjuster lever is designed to prevent excessive protrusion of the needle. It is an additional safety mechanism that stops the needle at 20 mm when required. The set includes a lockable syringe allows suction to be done single handedly during the procedure.

Single-use EBUS-TBNA aspiration needle - ViziShot 2

Improved access and enhanced lymph node penetration for more efficient sampling in EBUS-TBNA.

Single-use EBUS-TBNA aspiration needle - ViziShot 2

  • Improved flexibility
    Advanced needle design allows improved flexibility, helping to support access to targets in bronchi which are usually difficult to reach with conventional needles.
  • Safety mechanism
    ViziShot 2 incorporates a double-safety mechanism, the needle adjuster lever lock and the needle retrack lock.
  • Enhanced puncture capability
    The sharper needle tip design reduces the puncture force required to take a sample.
  • Ergonomic design
    New, easy-to-handle design with rubber finger gripper supports needle control and improves stability.
  • Increased sheath visibility
    Colored sheath tip increases visibility during endoscopic observation.
  • Efficient echogenicity
    Dimpled needle surface allows excellent ultrasound visibility.
