Access to a greater area of surgical site with minimally invasive procedure is obtained by using two sets of sequentially placed tissue dilators oriented with their axes in a plane parallel to the spinal axis and a final non- circular dilator encompassing the two sets, followed by a non-circular tubular retractor providing a working channel extending longitudinally of the spine.

On peut accéder à une grande zone de site chirurgical au moyen d'une procédure peu invasive par utilisation de deux ensembles de dilatateurs tissulaires séquentiellement disposés orientés selon leurs axes dans un plan parallèle à l'axe vertébral, et d'un dilatateur final non circulaire comprenant les deux ensembles, puis d'un rétracteur tubulaire non circulaire fournissant un canal d'accès s'étendant longitudinalement par rapport à la colonne vertébrale.
