A medical device includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A cutting member extends distally from the distal end of the elongated sleeve, and has sharp cutting edges. The cutting head is formed from a wear-resistant ceramic material, and a motor coupled to the proximal end of elongated sleeve rotate the cutting member. The cutter is engaged against bone and rotated to cut bone tissue without leaving any foreign particles in the site.
