Abstract

L'invention porte sur un tube de pliage d'un endoscope qui comporte des bagues nodales circulaires. Chaque bague nodale comprend deux articulations formées de façon symétrique par rapport à l'axe central de la bague nodale et utilisées pour relier de façon tournante la bague nodale à la bague nodale adjacente, une partie discontinue formée sur la bague nodale au moins en une position dans la direction périphérique, et une partie chanfreinée formée par biseautage de la partie d'extrémité formée par moulage à pression.
