Abstract

L'invention porte sur une caméra vidéo (212), un voyant blanc à diode électroluminescente (202) et un voyant à diode électroluminescente (213) d'une autre longueur d'onde qui sont disposés autour de la région où un instrument d'incision (201) pour pratiquer une incision dentaire. Une source de lumière (211), une alimentation électrique (210), un processeur de signaux numériques/unité centrale (207) et un émetteur (206) sont ménagés sur la pièce à main sur un seul côté. Un récepteur (206) reçoit un signal vidéo de la caméra vidéo (212) pendant l'incision et le convertit en une image de sorte que le chirurgien reconnaisse visuellement la partie à inciser. Un visualiseur comprend un écran d'affichage (215) que le chirurgien peut regarder pour effectuer le traitement et un moniteur (218) pour le patient. Lors de la visualisation des zones mortes que le dentiste ne peut voir directement, en temps réel, celui-ci peut effectuer le traitement et obtenir une bonne efficacité de traitement.
