Which retractor is typically used for retraction of the internal mammary artery?

The Favaloro retractor is specifically designed for the purpose of exposing the internal mammary artery by allowing precise and gentle retraction. Its unique design and shape enable surgeons to manipulate surrounding tissues effectively while maintaining a clear view of the surgical field, which is crucial for tasks such as harvesting the internal mammary artery during procedures like coronary artery bypass grafting.

In contrast, other retractors such as the Weitlaner, malleable retractor, and Richardson retractor serve different functions and may not provide the optimal alignment or access required for the internal mammary artery. While the Weitlaner is useful for holding back larger flaps of tissue, the malleable retractor is versatile but may not maintain the rigidity needed for this specific application. The Richardson retractor, commonly used for abdominal surgeries, also focuses on broader tissue retraction rather than the delicate retraction required for the internal mammary artery. Thus, the Favaloro retractor stands out as the best choice for this particular task.
