A steerable, tendon-driven endoscope is described herein. The endoscope has an elongated body with a manually or selectively steerable distal portion and an automatically controlled, segmented proximal portion. The steerable distal portion and the segment of the controllable portion are actuated by at least two tendons. As the endoscope is advanced, the user maneuvers the distal portion, and a motion controller actuates tendons in the segmented proximal portion so that the proximal portion assumes the selected curve of the selectively steerable distal portion. By this method the selected curves are propagated along the endoscope body so that the endoscope largely conforms to the pathway selected. When the endoscope is withdrawn proximally, the selected curves can propagate distally along the endoscope body. This allows the endoscope to negotiate tortuous curves along a desired path through or around and between organs within the body.

L'invention concerne un endoscope manoeuvrable, commandé par câbles. Cet endoscope possède un corps oblong avec une portion distale manoeuvrable manuellement ou sélectivement et une portion proximale segmentée, à réglage automatique. La portion distale manoeuvrable et le segment de portion réglable sont actionnés par au moins deux câbles. Lorsque l'endoscope est avancé, l'utilisateur manoeuvre la portion distale, et une commande de déplacement actionne les câbles dans la portion proximale segmentée de façon que la portion proximale suive la courbe sélectionnée de la portion distale manoeuvrable sélectivement. Grâce à ce procédé, les courbes sélectionnées sont propagées le long du corps de l'endoscope de façon que l'endoscope se conforme largement au trajet sélectionné. Lorsque l'endoscope est retiré de manière proximale, les courbes sélectionnées peuvent se propager de façon distale le long de l'endoscope. On permet ainsi à l'endoscope de négocier des courbes tortueuses le long d'un trajet recherché à travers, ou autour, et entre des organes corporels.
