The Sklar Blue Cusco Vaginal Speculum with Lateral Screw is a self-retaining speculum used for examination of, or procedures within, the vaginal canal. The blades of the Cusco speculum are opened, closed, and adjusted with the attached screw. Sklar Blue electrosurgical instruments feature high quality stainless steel with an insulated coating. This safe coating prevents radio frequency currents from being transmitted through the instrument which reduces the burning of non-targeted tissue.
