Abstract

La présente invention concerne un insert d'outil de piézochirurgie comprenant des lames (11, 21, 31, 41, 51, 61, 71) et des becs d'outil (12, 22, 32, 42, 52, 62, 72). Ces becs d'outil (12, 22, 32, 42, 52, 62, 72) sont situés juste en face des lames (11, 21, 31, 41, 51, 61, 71) de façon à diriger vers l'intérieur des becs d'outil (12, 22, 32, 42, 52, 62, 72) toute l'énergie de l'outil de piézochirurgie. Cet insert d'outil de piézochirurgie permet d'augmenter la vitesse de taille, de réduire le temps de fonctionnement, et de commander avec précision la quantité et la forme de l'os taillé.
