This invention is a corporeal access tube assembly (10) including a tube segment (41 ) in which a coil spring (42) is embedded along a portion of the segment. A retention balloon (20) is secured to the tube segment around a portion which does not contain the spring coil. The balloon is inflated when in operation but its walls are not stretched to any noticeable extent. The tube segment extends through a split external bolster (21) which opens to permit positioning of the tube segment and closes to clamp the tube segment in place. A gauging system on the tube segment permits precise positioning of the bolster.
L'invention concerne un ensemble tube (10) permettant d'accéder à l'intérieur du corps et comprenant un segment de tube (41) sur une partie duquel loge un ressort à boudin (42). Un ballonnet de retenue (20) est fixé au segment de tube autour d'une partie qui ne contient pas le ressort à boudin. Le ballonnet est gonflé quand on utilise l'ensemble mais ses parois ne sont pas sensiblement étirées. Le segment de tube s'étend à travers une partie extérieure (21) rembourrée et fendue s'ouvrant afin de pouvoir placer le segment de tube et se fermant afin de fixer ledit segment en position. Un système de calibrage situé sur le segment de tube permet de placer avec précision la partie extérieure rembourrée.
