Abstract
An arthroscopic or other surgical cutter has features which facilitate fabrication by ceramic molding. The arthroscopic cutter includes a cutter body having a longitudinal axis and a window, an interior channel, and a plurality of cutting edges extending radially outwardly from an outer surface thereof. The features include non-helical, longitudinally aligned cutting edges, controlled thicknesses of the cutting edges, controlled heights of the cutting edges, controlled areas of the windows, controlled diameters of the internal channels, controlled rake angles of the cutting edges, and other parameters.
