The Sims Speculum is a gynecological instrument used for visualizing the vaginal canal and cervix during pelvic examinations. It consists of a slender, curved blade with a rounded end and a handle for manipulation. The Sims Speculum is inserted into the vagina and then gently rotated to provide clear visibility of the cervix and vaginal walls. It is commonly used in procedures such as Pap smears, vaginal biopsies, and intrauterine device (IUD) insertions.
