"A speculum (Latin for "mirror"; plural specula or speculums), is a medical tool for investigating body orifices, with a form dependent on the orifice for which it is designed. In old texts, the speculum may also be referred to as a diopter or dioptra. Like an endoscope, a speculum allows a view inside the body; endoscopes, however, tend to have optics while a speculum is intended for direct vision." - (en.wikipedia.org 27.12.2020)
