Which instrument is used to hold sponges for skin preparation?

The Rampley sponge holding forceps are specifically designed to securely grasp and manipulate surgical sponges used for skin preparation. These forceps typically feature a serrated jaw, which provides a firm hold on the sponges, allowing for effective positioning and removal without slipping. Their design is optimal for maintaining a sterile field, which is essential in surgical environments where contamination must be minimized.

In contrast, the Hartmann crocodile forceps are more versatile and are generally used for grasping and holding tissues or for other surgical tasks, but they do not specialize in sponge handling. Similarly, Olsen-Hegar needle holders serve a dual purpose of holding needles during suturing and cutting suture material but are not intended for sponge management. Spencer stitch scissors are specifically designed for cutting suture material and have no function related to holding sponges.

Thus, the Rampley sponge holding forceps are uniquely suited for the task of handling sponges for skin preparation, making them the correct answer.
