In gynecology, a speculum is the instrument used to examine the cervix. It is a medical device that allows the clinician to open the vaginal walls, providing a clear view of the cervix and vaginal canal. Speculums can be made of metal or plastic and come in various sizes to accommodate different patients. This examination is often part of a pelvic exam or Pap smear procedure.
