Abstract Translated from German Instrument de prélèvement par abrasion de tissus osseux, comportant une tête d'abrasion connectée de façon libérable par l'intermédiaire d'un dispositif d'accouplement à l'élément moteur. La tête d'abrasion a la forme d'un cylindre creux avec une surface extérieure arrondie, les parois intérieures et/ou extérieures étant recouvertes d'une couche abrasive formée de particules dont la grandeur varie entre 30 et 300 mum. L'invention concerne également un cylindre creux de prélèvement, qui doit être utilisé avec l'instrument de prélèvement par abrasion de tissus osseux, et qui comporte, non pas un revêtement abrasif, mais des crochets qui pénètrent dans la moelle.
