WOUND RETRACTOR WITH SPLIT HOOPS

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.

1. An adjustable wound retractor comprising:
a flexible retraction sheath having a distal end, a proximal end, and an outer surface; a flexible inner ring insertable into a body cavity, the ring attached to the distal end of the retraction sheath; a first split-hoop comprising a first end and a second end; a second split-hoop comprising a first end and a second end; a first row of a plurality loops positioned around the outer surface of the retraction sheath near the proximal end of the sheath, the first row of loops sized and configured to receive the first split-hoop; and a second row of a plurality loops positioned around the outer surface of the retraction sheath near the proximal end of the sheath, the second row of loops positioned distal to the first row and sized and configured to receive the second split-hoop.
