The flexible straps of the surgical retractor may be frangibly connected together. LEDs molded into the distal end create a light source to illuminate the surgical site. The ring may take several forms including a flexible or adjustable ring and an inflatable bladder. The ring of the surgical retractor is inserted into the surgical incision, a patch of loop fastener is attached to the patient, a set of straps connected to the ring are pulled outward and the hook portion is applied to the loop portion to hold the incision open. The retractor is useable for thoracic and other types of surgery.
