Cusco's speculum

In gynaecology, Cusco's self-retaining bivalved speculum is a kind of speculums, used for vaginal and cervical examinations.

The instrument was named after French surgeon Édouard-Gabriel Cusco (1819–1894).

Cusco's speculum is used for introducing an intrauterine contraceptive device, taking a Pap smear, cauterization of vaginal erosion, and colposcopic examination.

[3] It is preferred in cryosurgery because it protects the anterior and posterior vaginal wall.

Because it covers most of the vaginal wall, small lesions on the vaginal wall may be masked by the blades of the device.
