Abstract
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.
