What is the function of a retractor during surgery?

The primary function of a retractor during surgery is to hold back tissues, which enhances visibility for the surgical team. By securing the edges of an incision or moving aside organs and other structures, retractors allow the surgeon to have a clear view of the surgical field. This increased visibility is critical for the precise execution of surgical procedures, as it helps prevent accidental damage to surrounding tissues and allows for better access to the area being operated on.

In contrast, cutting sutures is the role of scissors or specialized cutting instruments, while providing light to the surgical field is typically the function of surgical lights or fiber optic equipment. Clamping blood vessels is performed using hemostats or vascular clamps, which are specifically designed to occlude blood flow. The retractor simplifies the operative procedure by keeping tissues out of the way, ensuring the surgical team can work efficiently and safely.
