CA 2370271

A cannula (2) has a distal portion (6) which is angled relative to a proximal portion (4). The distal portion (6) is straightened during introduction with a stiffening element (14). After introduction, the stiffening element (14) is removed so that the distal portion (6) angulates relative to the proximal portion so that the cannula (2) can be moved out of the surgical field. The cannula (2) preferably includes a stabilizing ring (30) having suture holders. The stabilizing ring is also preferably angled relative to the cannula (2).

Selon cette invention, une canule (2) possède une partie distale (6) qui est recourbée par rapport à une partie proximale (4). Pendant l'introduction, la partie distale (6) est redressée au moyen d'un élément de renfort (14). Après l'introduction, l'élément de renfort (14) est retiré de manière à permettre à la partie distale (6) de se recourber par rapport à la partie proximale afin que l'on puisse retirer la canule (2) du site chirurgical. La canule (2) comprend de préférence un anneau stabilisateur (30) muni de supports de sutures. L'anneau stabilisateur est aussi, de préférence, recourbé par rapport à la canule (2).
