Abstract
A combination handle unit and tongue depressor includes a light source, a means for attaching a light-transmissive disposable depressor member to the handle to conduct light from the source into, for example, the mouth and throat of a patient being examined, and an adjustable lens which can be focussed into the illuminated area for viewing. The lens is mounted on the handle unit for sliding movement back and forth to change the focal plane so that different depths of the region being examined can be brought into clear focus.
