摘要：
A device, system and method for dilating a patient during a minimally invasive surgical procedure is disclosed. A surgical dilation system includes a dilator having an outer tubular member and an inner tubular member sized to be movably received within an inside diameter of the outer tubular member. The outer tubular member includes a vertical slot running through a side of the outer tubular member. The inner tubular member has an upper portion and a lower portion. The retractor has a proximal end including at least one mounting member protruding outwardly from a side surface of the retractor and a distal end including at least one fanned blade protruding outwardly from the side surface. When the inner tubular member is oriented in a first position the vertical slot is in a closed state, when the inner tubular member is oriented in a second position the mounting member is permitted to travel downwardly a predetermined distance in the vertical slot, and when the inner tubular member is positioned in a third state the mounting member is permitted to freely travel through the vertical slot.Linvention porte sur un dispositif, un système et un procédé pour la dilatation dun patient durant une intervention chirurgicale minimalement invasive. Un système de dilatation chirurgicale comprend un dilatateur ayant un élément tubulaire externe et un élément tubulaire interne dimensionnés pour être reçus de manière mobile à lintérieur dun diamètre interne de lélément tubulaire externe. Lélément tubulaire externe comprend une fente verticale sétendant à travers un côté de lélément tubulaire externe. Lélément tubulaire interne a une partie supérieure et une partie inférieure. Lécarteur a une extrémité proximale comprenant au moins un élément de montage faisant saillie vers lextérieur à partir dune surface latérale de lécarteur et une extrémité distale comprenant au moins une lame en éventail faisant saillie vers lextérieur à partir de la surface latérale. Lorsque lélément tubulaire
