In common use during the nineteenth century were the bivalve speculum of Phillip Ricord, the trivalve of P. Segalas, and the quadrivalve of J.F.B. Charriere. But the most popular form by far was the bivalve designed by Edward Gabriel Cusco, 1819-1894 which remains in use and was forerunner of the Graves’ speculum.

The mania for devising new vaginal speculums persisted for decades and resulted in more than two hundred distinct models being represented in the gynecological literature of the nineteenth century.

A nice example of Cusco’s classic form.
