Abstract

La présente invention concerne une tête d'ostéotome à ultrasons, comprenant une partie meulage positionnée à l'extrémité avant de la tête d'ostéotome à ultrasons, un corps d'ostéotome relié à un transducteur, et un cylindre d'ostéotome utilisé pour relier la partie meulage et le corps d'ostéotome. La partie meulage présente une structure trapézoïdale, le côté long de la structure trapézoïdale de la partie meulage formant le bord de l'extrémité avant de la tête d'ostéotome à ultrasons, et le côté court de la structure trapézoïdale se raccordant au cylindre d'ostéotome. La partie meulage comprend une face de meulage positionnée sur le côté supérieur de la partie meulage et une face inférieure positionnée sur le côté inférieur de la partie meulage, la face de meulage étant pourvue de rainures de meulage. Lorsque la tête d'ostéotome à ultrasons de la présente invention est utilisée pour effectuer une décompression sous-cutanée, des ostéophytes peuvent être retirés en toute sécurité de la profondeur à l'intérieur du corps sans endommager la moelle épinière. La tête d'ostéotome à ultrasons de la présente invention offre une structure simple, un traitement facile et une flexibilité en fonctionnement, et présente une large application.
