Speculum for viewing inner ear - has split tapered end section whose two halves are opened by pressure of inner speculum or by diametric pressure on other end

摘要

The speculum comprises an elongated cone with a thin tapering end which is split. The tapered end is inserted into the ear and a second conical speculum is slid inside it. A slight axial pressure on the inner cone causes the split end to open to provide a better view of the inner ear. In an alternative arrangement the speculum is split at both ends in diametrically opposed positions. When the two outer halves are pressed together the two inner, tapered halves are forced apart to widen the auditory canal.
