Abstract
A speculum for dilating a body cavity includes a base and a number of arms pivotably attached to the base. There is an actuator movably attached to the base for causing each of the arms to move relative to each other from a closed position to an opened position so that a body cavity can be smoothly opened after the arms have been inserted into the body cavity.
