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.

L'invention concerne un dispositif d'accès chirurgical composé d'un écarteur chirurgical ayant un anneau externe non souple avec un axe annulaire, un anneau interne et un manchon couplant l'anneau externe à l'anneau interne. L'anneau externe non souple est conçu pour rouler sur lui-même autour de l'axe annulaire pour faire rouler le manchon autour de l'anneau externe pour écarter et fermer une ouverture dans une paroi de corps biologique. Le dispositif d'accès peut comprendre un couvercle conçu pour être couplé à l'anneau externe non souple de l'écarteur chirurgical. L'anneau externe de l'écarteur chirurgical a une forme en coupe transversale qui empêche le couvercle d'être partiellement ou inexactement couplé à l'anneau externe de l'écarteur chirurgical.
