Which self-retaining retractor is commonly used during a total abdominal hysterectomy for retracting the pelvic wall?

The O'Sullivan/O'Connor retractor is specifically designed for use in gynecological surgeries, including total abdominal hysterectomy. This self-retaining retractor provides excellent exposure of the pelvic cavity by gently retracting the pelvic walls and the vaginal vault. Its unique design allows for optimal visibility and access to the surgical site while minimizing trauma to surrounding tissues.

In contrast, while the Thompson, Balfour, and Bookwalter retractors are also effective in various surgical procedures, they are not as commonly utilized in gynecological contexts, particularly for procedures like a total abdominal hysterectomy. The Thompson retractor is generally used in thoracic and abdominal surgeries, the Balfour retractor is more suited for abdominal surgeries and may not provide the customized retraction needed for pelvic work, and the Bookwalter retractor, although versatile, is often reserved for larger abdominal surgeries requiring extensive exposure rather than the focused area of the pelvis. This makes the O'Sullivan/O'Connor the preferable choice for this specific surgical procedure.
