Abstract
The invention relates to a device for performing endoscopic guided fine needle biopsy, in which the needle is automatically controlled by using a pre-biased needle. Upon release of a spring, the needle projects toward tissue, overcoming frictional forces, thanks to high acceleration. This reduces the danger of breaking the needle.
