The Fujinon EG-530N designed for upper G.I. tract endoscopy procedures is a trans-nasal device, with its slimmed-down distal end designed for insertion through the nose. The distal end measures only 5.9mm in diameter, yet this instrument meets the requirements for G.I. endoscopy. It features 4-way angulation, includes a forceps channel, and has a lighting system that eliminates shadows.
