The medical inspection device for eg. nmose cavities, has an eyepiece (13) suspended from a headband (15) worn by a surgeon. It has a fibreglass light conductor (12) suspended in front and a second eyepiece (7) so that another person, e.g. a student, can also use the instrument at the same time. In line with the viewing tube and viewing hole (2) through the concave mirror (3) for the surgeon, is a partly transparent prism, and at right angles to this viewing tube is a longer viewing tube (9) with one end towards the prism, and the other end carrying the second eyepiece (7). Thus the second viewer is alongside the first viewer, at the same level. |
