要約
(EN)
A joint ring (8) for an endoscope bendable tube (9) is configured so as to be fitted and affixed, at the axial distal end thereof, to a distal end hard member (21). The joint ring (8) is formed by plastically deforming a tube material and comprises: a joint ring protrusion (8a) which is fitted to a distal end hard recess (21a) provided in the distal end hard member (21), is used for positioning, and protrudes to the axial distal end side; and a joint ring recess (8d) which prevents the deformation of the joint ring protrusion (8a) when plastically deforming the tube material having the joint ring protrusion (8a) provided thereto and which is provided in the vicinity of the joint ring protrusion (8a) prior to the plastic deformation.
(FR)
La présente invention concerne une bague d'étanchéité (8) pour un tube pliable d'endoscope (9) configurée de façon à être adaptée et fixée, au niveau de son extrémité distale axiale, à un élément dur d'extrémité distale (21). La bague d'étanchéité (8) est formée en déformant de manière plastique un matériau de tube et comprend : une saillie de joint d'étanchéité (8a) qui est insérée dans l'évidement dur d'extrémité distale (21a) prévu dans l'élément dur d'extrémité distale (21), est utilisée pour le positionnement, et fait saillie jusqu'au côté d'extrémité distale axiale ; et un évidement de bague d'étanchéité (8d) qui empêche la déformation de la saillie de la bague d'étanchéité (8a) lors de la déformation plastique du matériau du tube au niveau duquel est prévue la saillie de la bague d'étanchéité (8a) et qui est prévu à proximité de la saillie de la bague d'étanchéité (8a) avant la déformation plastique.
