Filed:

Oct 12, 2006

Appl. No.:

11/548758

Inventors:

Jeremy J. Albrecht - Ladera Ranch CA, US
Jennifer T. Ko - Rancho Santa Margarita CA, US
Gary M. Johnson - Mission Viejo CA, US
John R Brustad - Dana Point CA, US
Donald L. Gadberry - San Clemente CA, US

Assignee:

Applied Medical Resources Corporation - Rancho Santa Margarita CA

International Classification:

A61B 1/32

US Classification:

600208, 600206, 600215

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 placed 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.

International Classification:

A61B 1/32

US Classification:

600206

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.
