Abstract

Le dispositif d'accès chirurgical présenté comprend un introducteur (100) composé d'un canal endoscopique principal et d'un canal auxiliaire ou secondaire destiné aux instruments. L'introducteur présente un profil extrêmement étroit en coupe transversale, afin de réduire au maximum la taille de l'orifice ou de tout point d'accès nécessaire pour pénétrer dans le corps du patient, ce qui permet de minimiser la douleur et l'inconfort pour le patient et d'effectuer une grande variété d'interventions endoscopiques sans hospitalisation. Lors de l'introduction, l'introducteur conserve son profil étroit grâce à un canal de guidage (118) qui peut être maintenu dans une première position afin d'épouser parfaitement le profil de l'introducteur. On confère au canal de guidage une certaine forme qui lui permet de garder la position refermée pendant l'introduction. Cependant, dès l'introduction terminée, le canal de guidage peut facilement reprendre sa forme pour se déployer et recevoir un instrument chirurgical secondaire. Ce canal de guidage peut être muni de rails ou de glissières quelconques afin de garantir la précision du déplacement de l'instrument jusqu'au point distal à atteindre. Le canal de guidage est constitué d'un matériau membranaire mince mais extrêmement résistant et non élastique. La présente invention concerne également un procédé de fabrication et d'utilisation de ce dispositif d'accès chirurgical.
