A method of surgical navigation into' the brain includes establishing a trajectory through the skull into the brain to a target, drilling a hole in the skull using a drill (14), and verifying the trajectory of the drilled hole during drilling using image guidance. A surgical navigation system includes a cannulated drill, a cannulated access member (30), and a coupling member (16) for coupling the access member to the drill and for maintaining alignment of the cannulations in the drill and the access member. The access member is movable relative to the coupling member such that the access member can be secured to tissue while the coupling member maintains the alignment of the cannulations. A surgical kit includes a cannulated drill, a cannulated access member, a coupling member for coupling the access member to the drill, and a probe for receipt within the cannulated drill.

L'invention concerne un procédé de navigation chirurgicale dans le cerveau comprenant l'établissement d'une trajectoire par le crâne dans le cerveau jusqu'à une cible, le perçage d'un trou dans le crâne en utilisant un foret (14) et la vérification de la trajectoire du trou foré pendant le forage en utilisant le guidage par image. Un système de navigation chirurgicale comprend un foret tubulaire, un élément d'accès tubulaire (30) et un élément de couplage (16) pour coupler l'élément d'accès au foret et pour maintenir l'alignement des tubes du foret et de l'élément d'accès. L'élément d'accès peut se déplacer par rapport à l'élément de couplage de sorte que l'élément d'accès peut être fixé au tissu tandis que l'élément de couplage maintient l'alignement des tubes. Un nécessaire chirurgical comprend un foret tubulaire, un élément d'accès tubulaire, un élément de couplage pour coupler l'élément d'accès au foret, ainsi qu'une sonde logée dans le foret tubulaire.
