Abstract

L'invention concerne un dispositif d'ablation par laser pourvu d'un système de positionnement à temps zéro. Ce dispositif d'ablation par laser comprend une pièce (14) à main dont le capteur (28) est adjacent à l'extrémité distale d'un tube (24) par lequel une fibre optique (12) sort de la pièce à main. Ce capteur (28) détecte la position de la fibre dans le tube (24) par détection d'un signal, telle que la lumière rouge émanant de la fibre avant la mise sous tension. A la détection du signal rouge, le capteur (28) envoie des informations en retour à un module (22) de commande qui peut suspendre la progression de la fibre. Le capteur peut comprendre un détecteur d'infrarouge, un photodétecteur, ou un détecteur de chaleur/température. Selon un autre mode de réalisation d'un système de positionnement à temps zéro, configuré pour la chirurgie fermée, un capteur (28) permet de détecter une marque sur la gaine de la fibre à mesure que la gaine de la fibre se déplace par rapport à la pièce (14) à main. Une fois la marque détectée, le capteur envoie des informations en retour au module de commande, qui peut suspendre la progression de la fibre.
