CA 2405764

A surgical distraction device is provided for applying extending or tensioning force non-invasively to a patient's skeleton or to an implant which comprises anchoring means for attaching first and second components of the device to a bone or to adjoining bones, said components being connected by a linkage of an extendible length, a magnet connected to the linkage via a reduction gearbox and actuating means located externally of the patient for generating a moving or varying electro-magnetic field, thereby causing the magnet to rotate and the linkage to be extended.

L'invention concerne un dispositif chirurgical de distraction destiné à appliquer une force de tension ou d'extension, de manière non invasive, sur le squelette d'un patient ou sur un implant qui comprend des moyens d'ancrage pour attacher les premier et deuxième constituants du dispositif à un os ou à des os contigus, ces constituants étant reliés par une liaison de longueur extensible, un aimant étant relié à la liaison au moyen d'une boîte de réduction et de moyens actionneurs situés extérieurement au patient et destiné à générer un champ électromagnétique mobile ou variable, faisant ainsi tourner l'aimant et provoquant l'extension de la liaison.
