A speculum is provided herein which includes first and second arms, connected by a hinge, each having a channel formed thereon adapted to the shape of an eyelid. First and second elements are respectively located on the first and second arms configured to cooperatively retain the first and second arms in select rotational positions. A slot is defined in the second arm to partially separate first and second portions of the second arm with the first portion being displaceable away from the second portion. The second element is located on the first portion. Advantageously, with this arrangement, the first portion acts as a spring-loaded hinge which applies not only biasing force to the second element for retention, but also permits the second element to be separable from the first element. The subject invention provides a mechanical feature beyond the inherent memory of the material for operation of the speculum.

Speculum with hinged portion

In one aspect, a speculum is provided herein which includes a first arm having a first channel formed thereon adapted to the shape of an eyelid; a second arm having a second channel formed thereon adapted to the shape of an eyelid; a hinge unitarily formed with the first and second arms, the hinge permitting the first and second arms to selectively rotate about an axis rotation, the selective rotation causing the first and second channels to selectively move closer and farther apart; and, a position retaining arrangement. The position retaining arrangement includes a first element formed unitarily with the first arm, and a second element formed unitarily with the second arm. The first and second elements are configured to cooperatively retain the first and second arms in a selected rotational position. Advantageously, with the subject invention, a unitary speculum may be formed which includes an adjustable position retaining arrangement.
