摘要：
An incrementally adjustable wound retractor, which provides access to a body cavity, includes a flexible retraction sheath, an inner ring having a diameter greater than the desired diameter of the wound incision attached to the distal end of the retraction sheath, and at least two rows of a plurality of loops disposed around the proximal end of the retraction sheath, each row of loops sized and configured to receive a noncompliant split hoop. The two split hoops may be rolled over each other and around the annular axis to retract the sheath with sufficient force to stretch the incision to the desired diameter.
