The Cusco Vaginal Speculum is a self-retaining, bivalve gynecological instrument commonly used for pelvic examinations and minor procedures such as Pap smears, intrauterine device (IUD) insertion, colposcopy, and cervical biopsies. Its design allows for hands-free operation, making it especially useful in outpatient and clinical settings.

🔧 Design & Structure

Handle: Compact and ergonomically designed for easy manipulation during procedures.
Material: Constructed from surgical-grade stainless steel, fully autoclavable and reusable. Disposable plastic versions are also available for single use.
Finish: Usually a satin or polished surface to minimize light reflection and improve patient comfort.
