Speculum (medical)
Summary
A speculum (Latin for 'mirror'; : 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.
Vaginal and anal specula were used by the ancient Greeks and Romans, and speculum artifacts have been found in Pompeii. The modern 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. This speculum is inserted into the vagina to dilate it for examination of the vagina and cervix.
The modern vaginal speculum was developed by J. Marion Sims, a plantation doctor in Lancaster County, South Carolina. Between 1845 and 1849, Sims performed dozens of surgeries, without anesthesia, on at least 12 enslaved women. In these experiments, Sims developed a technique to repair fistula and in the process invented the duckbill speculum. These experiments, and the development of the modern specula, led some to regard Sims as the "father of modern gynaecology."
By the 1860s, specula were integrated into criminal justice practices in the UK. In Great Britain, examinations of the cervix were made mandatory for all women convicted of prostitution by the country's Contagious Disease Act.
In the 19th century, the vaginal speculum became a cultural symbol of the tenuous relationship between women and their physicians. Use of the speculum was generally avoided in medical practices, and most vaginal conditions were diagnosed through symptoms or palpating the abdomen. Many practitioners had moral concerns about the use of the speculum, and preferred to diagnose through palpating the abdomen. As late as 1910, physicians believed the vaginal speculum to be inferior to the "educated touch.
