Speculum (medical)
A speculum is a medical tool for investigating body cavities, with a form dependent on the body cavity for which it is designed. Vaginal specula were used by the
Romans, and speculum
artifacts have been found in
Pompeii. A vaginal speculum, developed by
J. Marion Sims, consists of a hollow cylinder with a rounded end that is divided into two hinged parts, somewhat like the
beak of a duck. The speculum is inserted into the vagina to dilate it for examination of the
vagina and
cervix.
