ABSTRACT:
A surgical access device (10 or 10') includes a frame defining an access port and a pair of flanges are carried on the lower surface of the frame. The flanges are pivotable between an insertion position, where their leading edges are optimally placed adjacent one another to assist in inserting the device in an incision, and a retracting position, where both flanges optimally urge upwardly against the internal surface of the patient's tissue to seat the access port. A method of the invention involves making an incision at least as long as the leading edge of such a device and inserting the leading edge of the device into the incision. The flanges are moved laterally away from one another to expand the opening in the tissue and center the access port laterally within the opening.
