Cusco's speculum is used to inspect the cervix.
The speculum is lubricated (with lubricating jelly) and inserted with the blades closed and parallel to the labia. Once the speculum has been inserted into the vagina it is rotated and then opened. The cervix should pop into view as the speculum blades are opened. If the cervix is not seen then some gentle adjustment of the position of the speculum may reveal the cervix. If the cervix is not seen after gentle manipulation then withdraw the speculum. It may be necessary to perform a vaginal examination in order to ascertain the position of the cervix before repeating the procedure.
