Patent ID: 7883461

Claim:
A surgical access device comprising an adjustable wound retractor comprising: a flexible inner ring insertable into a body cavity; an outer ring comprising: a longitudinal axis; an annular axis; a resilient, ring-shaped body; a first circumferential lumen extending through the body; a second circumferential lumen extending through the body, axially spaced from the first circumferential lumen; a first split-hoop comprising a first end and a second end disposed in the first lumen; and a second split-hoop comprising a first end and a second end disposed in the second lumen; and a cross section comprising a longer axis; and a flexible, tubular sleeve comprising a first end coupled to the inner ring and a second end coupled to the outer ring, wherein the outer ring comprises resting states in which the outer ring is substantially non-compliant and the longer axis of the cross section of the outer ring is substantially parallel with the longitudinal axis of the outer ring; rotating the outer ring around the annular axis winds the tubular sleeve therearound, adjusting a length of the tubular sleeve between the inner ring and the outer ring; rotating the outer ring around the annular axis converts the outer ring between adjacent resting states through intervening transitional states; and in the transitional states, one of the first split-hoop and second split-hoop defines the annular axis.
