Apparatus and method for endoscopic examination of a tubular conduit are described. The apparatus is provided with an insertion tube fitted at a distal end thereof with an optical head for visualization of the conduit's interior. The insertion tube is coupled with a major inflatable sleeve, which upon inflation is capable of propelling the endoscope within the conduit. The insertion tube is also coupled with the at least one auxiliary inflatable sleeve, which upon inflation thereof provides additional propelling force for advancement of the insertion tube within the conduit. By inflating the major sleeve and the at least one auxiliary sleeve, it is possible to distribute the propulsion force along the insertion tube.
L'invention concerne un appareil et un procédé d'examen endoscopique d'un conduit tubulaire. L'appareil comprend un tube d'insertion doté, à son extrémité distale, d'une tête optique permettant la visualisation de l'intérieur du conduit. Le tube d'insertion est couplé à un manchon gonflable principal qui, lors d'un gonflage, est capable de propulser l'endoscope à l'intérieur du conduit. Le tube d'insertion est également relié à au moins un manchon gonflable auxiliaire qui, lors de son gonflage, produit une force de propulsion supplémentaire destinée à faire avancer le tube d'insertion à l'intérieur du conduit. Par gonflage du manchon principal et d'au moins un manchon auxiliaire, il est possible de répartir la force de propulsion dans le tube d'insertion.
