What is the primary purpose of retractors during a surgical procedure?

The primary purpose of retractors during a surgical procedure is to hold back tissues for better visibility. This function is crucial as it allows the surgeon to access the surgical site without obstruction from surrounding tissues. By providing a clear view and unobstructed access, retractors enhance the surgeon's ability to perform the procedure safely and effectively. They help minimize the risk of injury to surrounding structures by keeping them out of the way, which is essential during delicate or intricate surgeries. This use of retractors is fundamental in ensuring that the surgical area is adequately exposed and that the procedure can be conducted with precision.
