Grave Speculum 76 x12 mm

The Graves vaginal speculum is another commonly used instrument in gynecology for vaginal and cervical examinations. It differs slightly from the Cusco speculum in design and function but serves a similar purpose of providing visual access to the cervix.

Key Features:

1. Bivalve Design: Like the Cusco speculum, the Graves speculum also has two blades. However, the blades of the Graves speculum are typically wider and more rounded.
2. Duckbill Shape: The blades of the Graves speculum have a more pronounced duckbill shape, which helps in spreading the vaginal walls gently while providing a wide field of view.
3. Self-Retaining: Once the blades are inserted into the vaginal canal and opened, the Graves speculum has a mechanism that locks it into place, allowing hands-free operation for the healthcare provider.
4. Hinge and Adjustment Mechanism: The blades are controlled by a central hinge and an adjustable screw mechanism, allowing for gradual opening and closing. The tension screw holds the blades in position at the desired width.
5. Sizes: Graves speculums come in various sizes (small, medium, large), and there are models designed for both nulliparous women (those who haven’t given birth) and multiparous women (those who have given birth), accounting for the different sizes of the vaginal canal.
6. Material: Usually made from stainless steel (reusable) or plastic (disposable). Stainless steel versions are often autoclavable for sterilization.
7. Rounded, Full Blades: The blades are generally broader than those of the Cusco speculum, making the Graves speculum particularly useful when a wider view or greater access is needed.

The Graves vaginal speculum is frequently used in routine gynecological exams, including Pap smears, as well as for procedures such as IUD insertions and biopsies. Its wider design can make it more comfortable for some patients while providing better access for more complex procedures.
