The Balfour retractor is specifically designed to increase exposure of the abdominal cavity during surgical procedures. Its structure allows for the retraction of the abdominal wall, which creates a wider opening and provides enhanced visibility and access to the surgical site. This is crucial in surgeries requiring prolonged access to the abdominal organs, as effective exposure can facilitate the surgical maneuvers needed to perform the operation successfully.

The retractor's design typically includes blades that can be adjusted to different angles, ensuring that the surgeon can maintain the necessary exposure throughout the procedure. This capability is important because proper exposure can lead to better outcomes and reduce complications by allowing the surgeon to operate with improved precision and scope.

In the context of the other options, while certain retractors may provide stability or grasp tissues, the defining feature of the Balfour retractor is its primary role in enhancing visibility of the surgical area, validating the selection of the correct answer.
