Which retractor is commonly used in vaginal hysterectomy procedures?

The Graves retractor is a commonly used instrument in vaginal hysterectomy procedures due to its design, which is specifically tailored for gynecological surgeries. The Graves retractor features a curved and angled shape that allows for optimal visualization and access to the vaginal canal. Its structure provides excellent retraction of the vaginal walls, enabling the surgeon to have better access to the cervix and uterus during the procedure.

The other retractors might be useful in different surgical contexts but are not typically utilized for vaginal hysterectomy. The Weitlaner retractor, while effective in holding tissue in position, is more suited for superficial surgical fields. The Balfour retractor is designed for abdominal surgery, primarily providing broad access to the abdominal cavity. The Murphy retractor is used in various surgeries but is less specialized for procedures involving the vaginal space. Thus, the Graves retractor's specific design and applicability to the surgical needs encountered during vaginal hysterectomy make it the preferred choice.
