Endoscopic endotracheal intubation system consisting of a laryngoscope made of a stainless steel shaft (external diameter 6 mm) in which 7000 optical fibers are installed as a bundle having a malleable portion of 185 mm like a stylet and straight rigid portion of 195 mm attached with a holder grip at the middle portion, a light source, an image amplifier, a CRT monitor and a video recorder was developed for oral blind endotracheal intubation. The coherent fiber optic bundle transmits an image from the distal lens to the proximal CCD placed at the proximal end of the laryngoscope. The distal tip of the shaft where lens open was placed a few millimeter proximal to the tip the transparent endotracheal tube. The bent shaft like a stylet inserted into an endotracheal tube was orally introduced into larynx. Blind oral endotracheal intubation was successfully performed with CRT monitoring using this laryngoscope system. This system enabled tracheal wall observation through the transparent tube wall.
