Which handheld retractor is typically used on breast tissue during a mastectomy?

The Berens retractor is specifically designed for use in breast surgery, particularly during procedures such as a mastectomy. Its unique shape allows it to effectively hold back breast tissue, providing optimal exposure to the surgical area while minimizing trauma to the surrounding tissues. This retractor is particularly useful due to its ability to be maneuvered in tight spaces and to accommodate the different contours of the breast.

In contrast, other retractors mentioned are less suited for this specific application. Malleable retractors, while versatile and adaptable, may not provide the precise support needed during a mastectomy. The Richardson retractor is typically used for abdominal and pelvic surgeries, offering broader exposure rather than the targeted retraction of breast tissue. The Weitlaner retractor is also used primarily in abdominal and orthopedic surgeries and does not possess the characteristics needed for retracting breast tissue effectively.

Thus, the Berens retractor stands out as the most appropriate choice specifically for its function and design in breast surgical procedures.
