ABSTRACT:
An improved single use vaginal speculum with lateral retracting bills is disclosed. Each of the lateral retracting bills is supported on an axially rotatable shaft mounted to a side of the yoke of the lift mechanism which raises the lower bill assembly away from the lower bill and handle member. The lateral bills separate by action of levers which are moved when the upper bill is rotated about its pivot on the yoke. The lift mechanism may be slid along a channel in the handle when a push button is depressed and latched when the push button is released. The observation opening of the vaginal speculum is enlarged and the lateral bills are supported to prevent their obstructing the observation of the user in examining the cervix and vaginal walls. The handle mounted to the lower bill is rotated rearward from a perpendicular and finger indentations are formed around the handle. A reservoir is formed in the lower bill and an evacuation duct extends from the reservoir to the exterior of the handle to allow suction of liquids from the reservations. A fiber optic cable is passed through the handle and is fixed to the upper concave surface of the lower bill and is terminated away from the distal end of the lower bill to direct light from the fiber cable toward the interior of the vagina.
