  • Publication number: 20170333024
    Abstract: 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.

  • Patent number: 9101354
    Abstract: An incrementally adjustable wound retractor, which provides access to a body cavity, includes an inner ring having a diameter greater than the desired diameter of the wound incision, an outer ring having an annular axis and a diameter greater than the desired diameter of the wound incision, and a flexible sleeve disposed in a generally cylindrical form between the inner and outer rings. The outer ring includes first and second circular tubes spaced apart axially with each including a lumen having a rigid, noncompliant split hoop positioned therein. The outer ring may be rolled over itself and around the annular axis to retract the sleeve with sufficient force to stretch the incision to the desired diameter. A gel cap seal may be coupled to the outer ring outside of the biological body to seal the opening produced by the wound retractor between the body cavity and outside the body cavity.

  • Patent number: 8961410
    Abstract: A surgical access device has a surgical retractor having a noncompliant outer ring with an annular axis, an inner ring, and a sleeve coupling the outer ring to the inner ring. The noncompliant outer ring is adapted to roll over itself around the annular axis to roll the sleeve around the outer ring to retract and seal an opening in a biological body wall. The access device may include a lid adapted for being coupled to the noncompliant outer ring of the surgical retractor. The outer ring of the surgical retractor has a cross-sectional shape that prohibits the lid from being partially or incorrectly coupled to the outer ring of the surgical retractor.
