摘要：
The invention relates to an ultrasonic cutting device (100) for osteotomy, said device comprising: - a blade (110) extending in a longitudinal direction (L)； - an attachment member (120) configured to be connected, through a suitable extension member, with a handpiece configured to generate vibrations that are mainly directed in said longitudinal direction (L), said attachment member being connected to a proximal end (111) of said blade (110)； wherein the blade (110) further comprises a plurality of cutting elements formed on a distal portion (112) thereof, The cutting elements of the distal portion (112) comprise: - an arcuate portion (113) arranged at a free end of said distal portion (112) in the longitudinal direction (L), said arcuate portion (113) having a continuous cutting edge (114)； - a plurality of teeth (117, 118) having a triangular shape, said teeth (117, 118) being formed on opposite sides of the blade (110) symmetrically with respect to a longitudinal axis (A) thereof, the teeth (117, 118) being aligned with each other along respective directions that are incident relative to said longitudinal axis (A), the overall configuration of the distal portion (112) of the blade (110) being symmetrical relative to the longitudinal axis (A) and progressively widening from the arcuate portion (113) towards the proximal portion (111) of the blade (110) in the portion where the teeth (117, 118) are formed.L'invention concerne un dispositif de coupe ultrasonique (100) pour ostéotomie, ledit dispositif comprenant : - une lame (110) s'étendant dans une direction longitudinale (L)； - un élément de fixation (120) conçu pour être connecté, par l'intermédiaire d'un élément d'extension approprié, avec une pièce à main configurée pour générer des vibrations qui sont principalement dirigées dans ladite direction longitudinale (L), ledit élément de fixation étant relié à une extrémité proximale (111) de ladite lame (110)； la lame (110) comprenant en outre une pluralité d'élé
