Rotary EUS-FNA is a completely new medical device used in Endoscopic Ultrasound Fine Needle Aspiration. It is placed in an endoscope to perform biopsy in the gastrointestinal tract.
Rotary EUS-FNA was designed in a collaboration between Cook Medical and MSC Medical Device Design at the NCAD Dublin. It is a completely new medical device used in Endoscopic Ultrasound Fine Needle Aspiration (EUS- FNA). It is placed through the working channel of an ultrasonic endoscope and used to perform biopsy from suspect lesions in organs accessible through the gastrointestinal tract.
The handle of the Rotary EUS-FNA rotates to extend the needle allowing an endoscopist to apply greater force without losing control. This was inspired by insights of how feedback is provided by the ultrasound image. It makes use of an informal technique called the ‘slow pull technique’, usually performed by an endoscopist and a nurse who work as a team. Rotary EUS-FNA improves on the technique by enabling it to be carried out by a single user. It also removes the possibility of contamination of the 1.8-metre-long stylet as it can easily touch unsterile surfaces such as the bed and the patient’s clothing.
