An instrument for insertion into the body which includes a flexible image-transmitting element, a flexible light guide, and in some embodiments, a channel for intubation gas, which instrument contains a head for receiving a connection for the image-transmitting element. Because of their flexibility, they can variably be curved. To enable the doctor readily to follow the curvature during the insertion of the elements, an eyepiece is connected to the head by a joint or hinge. This enables the doctor to follow the varying direction during insertion of the instrument, because the angle between the head and the eyepiece member can be varied during insertion. |
