A method for treating a brain tumor includes providing a surgical instrument having an inner member and an outer member. The outer member has a distal region forming a cutting window. The inner member is rotatably received within the outer member, and has a cutting tip that is exposed at the window. The cutting tip and the distal region of the outer member combine to define a cutting implement. An opening is created through the patient's skull to provide access to a brain tumor target site. The cutting implement is delivered through the opening to the target site. The cutting tip is placed into contact with the tumor and operated to cut the tumor. The target site is selectively aspirated to remove cut tumor tissue.

L'invention concerne un procédé de traitement d'une tumeur cérébrale qui comprend l'utilisation d'un instrument chirurgical comportant un élément interne et un élément externe. L'élément externe comporte une région distale formant une fenêtre de découpe. L'élément interne est accueilli avec faculté de rotation à l'intérieur de l'élément externe, et comporte une pointe de découpe qui est exposée au niveau de la fenêtre. La pointe de découpe et la région distale de l'élément externe se combinent pour définir un outil de découpe. Une ouverture est créée à travers le crâne du patient pour permettre l'accès à un site cible de tumeur cérébrale. L'outil de découpe est introduit par l'ouverture vers le site cible. La pointe de découpe est placée au contact de la tumeur et actionnée pour couper la tumeur. Le site cible est sélectivement aspiré pour retirer le tissu tumoral découpé.
