Patent

CA 2629780

An endoscopic surgery apparatus is provided, including a tubular member, a handle located on a proximal end of the tubular member, and one or more pivotable arms detachably connected to a distal end of the tubular member. The tubular member has channels along its longitudinal axis, wherein at least one of the channels is an optical channel and at least one other channel is an illumination channel. The arms have guiding channels adapted to receive surgical tools, which direct the surgical tools. The arms are interchangeable with other arms of different configurations. Also, said arms have an open and a closed position, such that when the arms are in the closed position an opening is defined allowing viewing of a surgical site via the optical channel.

La présente invention concerne un instrument chirurgical endoscopique, qui comprend un élément tubulaire, une poignée située à une extrémité proximale de l'élément tubulaire, et un ou plusieurs bras pivotants reliés de façon non permanente à une extrémité distale du même élément tubulaire. Ce dernier comporte des entailles le long de son axe longitudinal, où au moins une des entailles constitue un canal optique et au moins une autre entaille sert de canal d'éclairage. Les bras sont munis d'entailles guides adaptées pour recevoir des instruments chirurgicaux; ces guides dirigent lesdits instruments. Les bras sont interchangeables avec d'autres bras configurés autrement. De plus, lesdits bras ont une position d'ouverture et une position de fermeture, de telle sorte que lorsque les bras sont à la position fermée, une ouverture est définie qui permet le visionnement d'un champ opératoire par le canal optique.
