A device for retracting edges of an incision in a surface to form an opening including: a flexible, tubular skirt having an upper end, a lower end, and a channel therebetween; a ring connected to the lower end of the skirt for maintaining the lower end in an open configuration and defining an exit opening to the channel; and an inflatable collar connected to the skirt and surrounding the upper end. The ring is designed to fit through the incision and remain under the surface when it is oriented parallel to the surface. The collar, when inflated, maintains the upper end in an open configuration and defines an entry opening to the channel. During use, the ring is inserted through the incision and the collar is inflated while-remaining outside of the incision, thereby drawing the skirt against the edges of the incision and retracting the edges of the incision to form the opening. The retracting device can be included in a surgical access port, which further includes a flexible sleeve connected to at least one of the inflatable collar and the skirt, extending the channel from the exit opening of the skirt to an open end of the flexible sleeve distal to the skirt. The device can include a light source in the vicinity of the exit opening.

L'invention porte sur un dispositif de retrait des lèvres d'une incision pratiquée dans une surface pour former une ouverture comportant: une jupe tubulaire souple présentant une extrémité supérieure et une extrémité inférieure reliées par un canal; un anneau relié à l'extrémité inférieure et maintenant ouverte l'extrémité inférieure et délimitant l'orifice de sortie du canal; et un collier gonflable relié à la jupe et entourant l'extrémité supérieure. L'anneau est conçu pour s'adapter à l'incision et rester sous la surface alors qu'il est orienté parallèlement à la surface. Le collier une fois gonflé maintient l'extrémité supérieure ouverte et délimite l'orifice d'entrée du canal. Pendant l'utilisation, on insère l'anneau dans l'incision et on gonfle le collier qui reste hors de l'incision et qui écarte la jupe contre les lèvres de l'incision et constitue l'ouverture. Le dispositif d'écartement peut se placer dans un orifice d'accès chirurgical qui par ailleurs comporte un manchon souple au moins relié au collier gonflable ou à la jupe prolongeant le canal de l'orifice de sortie à l'extrémité ouverte du manchon souple en aval de la jupe. Le dispositif peut comporter une source lumineuse voisine de l'orifice de sortie.
