The speculum has a jaw that opens up like a duck bill.
It comes in three models: side screw, center screw, and a special narrow virgin size.
The instrument is usually 80 millimeters (3.1 inches) long and 22 millimeters (0.87 inches) broad, but smaller and larger sizes are available.
It features a spring handle to open the blades and a screw mechanism to keep the blades open in the vaginal canal.
Uses:
Diagnostic Examinations: Cusco’s speculum is used for introducing an intrauterine contraceptive device, taking a Pap smear, and performing colposcopic examinations.
Cryosurgery: It is preferred in cryosurgery because it protects the anterior and posterior vaginal wall.
Cauterization: The speculum can be used for cauterization of vaginal erosion.
Self-Retaining: One advantage is that it is self-retaining, eliminating the need for an assistant to hold it in place during procedures.
Vaginal Wall Retraction: It also acts as a vaginal wall retractor.
Considerations:
While it provides excellent visibility, it reduces the space in the vaginal cavity, making it less suitable for extensive vaginal surgery.
Small lesions on the vaginal wall may be masked by the blades due to its coverage.
