Optical mandrel intended to perform tracheal intubations easily and in complete safety with visual monitoring. The intubation technique relating to the present invention is to introduce in advance, inside an intubation tube, an optical apparatus of small size (optical mandrel) which is rigid and bent at its end in order to preform the intubation tube and thus to perform in all cases the tracheal intubation in complete safety and while being able to see the vocal cords. The optical mandrel comprises a rigid stainless steel sheath 1 in which there is positioned an image guide optical system 2, at the periphery of which there is situated a light guide 3. The end of the optical mandrel 4 is bent and makes an angle of approximately 30 DEG with the principal axis of the mandrel. The stainless steel sheath 1 is coated with a plastic sheath 5 allowing easy sliding of an intubation tube 6. An objective 7 allows the image to be picked up and an eyepiece 8 allows the eye 9 to see it. The optical mandrel according to the invention is intended to facilitate tracheal intubations with visual monitoring and in complete safety. <IMAGE>
