Patent ID: 7913697

Claim:
A surgical access device comprising: a proximal end, a distal end, and an instrument access channel extending from the proximal end to the distal end; a wound retractor comprising a proximal end and a distal end, an outer ring at the proximal end, a deformable inner ring at the distal end, and a flexible, tubular sleeve extending from the outer ring to the inner ring; an annular base comprising a central opening; a cap comprising a working channel therethrough, wherein in an operative state of the access device, the cap is coupled with the annular base, thereby capturing the outer ring of the wound retractor therebetween, and the tubular sleeve of the wound retractor extends through the central opening of the annular base; and a retractor shield comprising a proximal end, a distal end, an interior, and an exterior, wherein in the operative state, the proximal end of the retractor shield is proximal to the proximal end of the wound retractor, and the distal end of the retractor shield extends into the tubular sleeve of the wound retractor, wherein in the operative state, the instrument access channel extends through the working channel of the cap, the interior of the retractor shield, the annular base, the outer ring of the retractor, the tubular sheath of the retractor, and the inner ring of the retractor.
