speculum

Vaginal Speculum is a medical examination tool used by healthcare providers to examine the vaginal walls and cervix. This device consists of two hinged blades that can be opened to dilate the vaginal canal, allowing for visual inspection, collection of samples, or performing minor procedures. Modern specula are typically made of sterile plastic or stainless steel and come in various sizes to accommodate different patients.

The speculum has been a crucial instrument in gynecological examinations since its modern redesign by J. Marion Sims in the 1840s, though similar devices were used as far back as ancient Rome. Today's versions often include features like smoke extraction capabilities for surgical procedures and improved comfort designs.
