Abstract

Instrument chirurgical pour l'extraction de fragments magnétiques. Cet instrument comprend un corps 2 en matière non magnétique terminé par une pointe effilée 1 en matière ferromagnétique et dans lequel on peut déplacer un aimant permanent 5 pour l'amener contre la pointe et magnétiser fortement cette dernière ou au contraire l'éloigner de la pointe pour la démagnétiser. L'aimant est solidaire d'une vis de translation 8 que l'on peut déplacer au moyen d'un écrou 15 commandé en rotation par un moteur 21. Un dispositif comprenant un balai 17 et des barrettes 30 provoque un ralentissement du moteur au moment où l'aimant s'approche de la pointe afin d'atténuer le choc de butée en fin de course. Application à l'extraction chirurgical de fragments ferromagnétiques, notamment de l'oeil.
