Abstract

L'invention porte sur un dilatateur qui facilite une implantation d'un espaceur interépineux. Le dilatateur comprend une partie proximale et une partie distale effilée reliées entre elles par une partie corps allongée. La partie distale effilée est idéalement adaptée pour la séparation d'un tissu ligamentaire afin de créer un trajet de ligne médiane postérieur à travers le ligament sus-épineux ainsi que pour la distraction des apophyses épineuses adjacentes. Deux canaux ou rainures situés de manière opposée et s'étendant longitudinalement sont formés dans la surface externe du dilatateur pour stabiliser le dilatateur par rapport aux apophyses épineuses. Une canule accompagnante conjointement avec le dilatateur forment un système pour la distraction des apophyses épineuses adjacentes, la stabilisation des apophyses épineuses par rapport au système et la création d'un canal de travail pour l'implantation d'un espaceur interépineux.
