Abstract
A vaginal speculum consisting of two blades pivotally interconnected through a fork-like member so that the blades can be expanded and fixed in an expanded state in order to dilate the vagina for observing the condition of the vagina cavity. The device is characterized by having adjustable blades, which can be withdrawn partially or completely for replacement with blades of other dimensions without withdrawing the entire speculum from the vagina. In a closed state, the distal ends of the blades form a bifocal lens, which can be used for visually detecting changes, associated with an earlier stage of cancer or erosion. Provision of retractable blades makes it possible for a physician to withdraw the blades in an alternating sequence for exposing one of the walls of the vagina cavity by pressing down with the longer blade on the opposite wall.
