What is the main surgical role of the O'Connor-O'Sullivan retractor?

The O'Connor-O'Sullivan retractor is specifically designed to facilitate access in gynecological surgeries, which is why this option is the correct choice. This retractor is particularly valuable during procedures involving the pelvic area because it allows for optimal visualization and access to the surgical site while holding back structures that could obstruct the view. Its design accommodates the anatomical complexities of the female pelvis, making it an essential tool for gynecologists.

In contrast, while the retractor may indirectly assist in holding back abdominal organs to some extent, its primary function is not merely to do that but rather to enhance access and visibility for the surgeon. Stabilizing the surgical field during suturing is typically handled by other instruments or devices that provide a more secure hold on tissues, rather than an access-focused retractor. Securing the patient's limbs is also outside the intended use of the O'Connor-O'Sullivan retractor, and that function is typically addressed with different types of restraints or supports during surgery.
