ABSTRACT:
An expandable speculum is described which may be provided in kit form. The speculum includes a handle with an integral eyepiece. A set of first elongated tubular members, each releasably connectable to the handle adjacent the eyepiece are formed of a substantially rigid material. Each includes an external surface and an internal bore formed along a longitudinal axis. A selected one of the tubular members may be selected and attached to the handle. The elongated tubular members in the set include various lengths and cross-sectional dimension at the external surfaces thereof to permit selection according to use and patient physiology. Elastic tubular sheaths are disposed axially over the external surfaces of the first elongated tubular members and are radially inflatable with respect to the first tubular members and said longitudinal axis in response to application of fluid pressure. Any one of the tubular members is releasably attachable to the handle in such a manner that the eyepiece is in axial alignment with the internal tube bore. Any one member and the sheath mounted thereto may be inserted in an orifice defined by supportive tissues, with the sheath in a deflated state, the sheath being inflatable in the orifice to engage and expand against the supportive tissues and thereby secure the speculum axially within the orifice while permitting angular movement of the handle and first tubular member with respect to the inflated sheath and the engaged supportive tissue.
