Abstract[English]
An endoscope has a narrow, metal cannula for insertion into the body of a patient. The distal tip of the endoscope has substantially the same outer diameter as the rest of the cannula when no tool is being passed through its working channel. When a tool is passed through the cannula the distal tip expands to a larger diameter to accommodate the tools outer diameter. The endoscope distal tip includes one or more compliant flexure mechanisms formed by cuts in the metal that facilitate its expansion when a tool is inserted and retraction due to the resiliency of the metal when a tool is withdrawn. The endoscope has an imaging sensor with a direction of view the is substantially unchanged when a tool is inserted.[French]
Un endoscope comporte une canule métallique étroite destinée à être insérée dans le corps d'un patient. La pointe distale de l'endoscope présente sensiblement le même diamètre externe que le reste de la canule lorsqu'aucun outil n'est passé à travers son canal de travail. Lorsqu'un outil est passé à travers la canule, la pointe distale s'étend jusqu'à un diamètre plus grand pour recevoir le diamètre externe d'outil. La pointe distale d'endoscope comprend un ou plusieurs mécanismes de flexion conformes formés par des découpes dans le métal qui facilitent son expansion lorsqu'un outil est inséré et sa rétraction due à la résilience du métal lorsqu'un outil est retiré. L'endoscope comporte un capteur d'imagerie dont la direction de vision est sensiblement inchangée lorsqu'un outil est inséré.
