Abstract
A compact, low-profile surgical retractor (100) avoids the need for a bulky frame. The retractor includes retractor blade components (110, 120, 130, 140, 150, 160) joined pivotally. A cable (170) is guided by each retractor blade component. A winding mechanism (180), such as a spool, is carried by one of the retractor blade components (120) for winding up the cable to cause the retractor blade components to transition from a closed position to an open position. The winding mechanism may be actuated by a detachable handle (200). The retractor blade components may be unitary, injection-molded pieces. The retractor blade components may be fixed pivotally, such as by pins, or pivotally joined by living hinges. A less-invasive surgical method is also provided in which the retractor is inserted into the body through an incision.
