Abstract

La présente invention concerne un dispositif de foret médical. Ce dispositif de foret médical, selon la présente invention, comprend : un foret de perçage comprenant un moteur et une partie foret ; un corps de dispositif couplé au foret de perçage ; et une pluralité de supports couplés au corps du dispositif de façon à soutenir le foret de perçage dans une région d'opération. Le support comprend : une partie droite insérée dans une partie d'insertion de support de manière à permettre un mouvement linéaire par rapport au corps du dispositif ; et une partie courbe, courbée à partir de la partie droite à un angle prédéterminé. Par conséquent, ce foret de perçage est soutenu dans la région d'opération par utilisation des supports présentant une structure courbe, et la profondeur de perçage du foret de perçage est limitée, ce qui permet ainsi de raccourcir le temps de perçage et d'assurer la stabilité d'une opération de perçage.
