Which retractor has sharp disposable inserts that require disposal in a sharps container?

The Mayfield retractor is specifically designed for neurosurgical procedures and features sharp disposable inserts that are critical for maintaining a clear surgical field during operations involving delicate tissues. The sharpness of these inserts allows for effective retraction of the scalp and underlying tissues without excessive trauma, which is vital in neurosurgery to protect nerve structures and blood vessels.

When these sharp inserts are used, they create a significant risk for injury if not handled properly. Therefore, they need to be disposed of in a sharps container, which is a standardized protocol in surgical environments to ensure safety and biohazard compliance. This is an essential aspect of surgical practice, as it helps prevent needle-stick injuries and the potential transmission of infections.

While other retractors listed, such as Cloward, Bookwalter, and Greenfield, serve specific functions in various surgical disciplines, they do not possess the sharp, disposable inserts characteristic of the Mayfield retractor.
