Abstract:
A surgical retractor (10) is adapted for use in opening an incision (12) in a body wall (14) to facilitate access into a body cavity. The retractor includes an interior anchor (16) that is disposed interiorly of the body wall and an exterior tensioning device (56) that is disposed exteriorly of the body wall. At least one tension element (21) is coupled to the interior anchor and adapted to pass through the incision to engage the exterior tensioning device. Engaging elements (59, 62) are provided on the exterior tensioning device to engage the tension element and to maintain a tensile force on the tension element as it passes through the incision. Multiple concentric rings can also be used to maintain a tensile force on the tension element.
