Surgical apparatus and associated methods of use are provided for retracting tissue around an incision. The apparatus includes a member having an inner peripheral surface and an outer peripheral surface. An adjustable aperture is definable within the inner peripheral surface as the member is adjusted between a compressed condition in which the aperture is substantially closed and an expanded condition in which the aperture is substantially open. The apparatus is positioned within a surgical incision in the compressed condition, and is adjusted to the expanded condition in situ to define an opening within incision through the aperture whereby a surgical field may be viewed and/or accessed.
L'invention se rapporte à un appareil chirurgical et à des méthodes associées permettant d'écarter les tissus autour d'une incision. Ledit appareil comporte un élément ayant une surface périphérique interne et une surface périphérique externe. Une ouverture réglable peut être définie dans la surface périphérique interne à mesure que l'élément est ajusté entre une position de compression dans laquelle l'ouverture est sensiblement fermée et une position d'extension dans laquelle l'ouverture est sensiblement ouverte. Ledit appareil est positionné à l'intérieur d'une incision chirurgicale en position de compression, et il est réglé de façon à adopter la position d'extension in situ permettant de définir une ouverture dans l'incision par laquelle il est possible de visualiser et/ou d'accéder à un champ opératoire.
