Abstract

La présente invention concerne un appareil de coupe d'os de mâchoire comprenant un outil de coupe d'os permettant de couper un os de mâchoire et une machine de propulsion d'outil permettant d'appliquer à l'outil de coupe d'os une force de propulsion vers l'avant. L'outil de coupe d'os est chargé dans la machine de propulsion d'outil de sorte que l'outil de coupe d'os puisse avancer vers l'avant, et la machine de propulsion d'outil reçoit et supporte l'outil de coupe d'os. Selon la présente invention, une opération de coupe pour un os de mâchoire, plus particulièrement un os cortical, peut être réalisée rapidement et avec précision, et les craintes et pressions visuelles pour une opération de découpe d'os de mâchoire, qu'un patient peut ressentir, peuvent être considérablement réduites. De plus, une distance d'avancée vers l'avant d'un outil de coupe d'os peut être ajustée, de sorte que l'appareil puisse effectuer de manière stable une opération de coupe d'os de mâchoire, telle qu'une résection d'os cortical, à une profondeur appropriée pour la structure anatomique d'un patient et pour un objectif de l'opération.
