The disposable bivalved plastic vaginal speculum is used in office gynecology
A speculum (Latin for "mirror") (plural specula or speculums) is a medical tool for investigating body cavities, with a form dependent on the body cavity for which it is designed. In old texts, the speculum may also be referred to as a diopter or dioptra.[1] Like an endoscope, a speculum allows entry into a body cavity, endoscopes, however, tend to have optics while a speculum is intended for direct vision.
