A surgical cutting instrument comprises an outer tubular member (18) and an inner tubular member (22). The outer tubular member includes a proximal section (40), an intermediate section (42), a distal section (44), and a side wall (60). The side wall defines a central lumen (46) extending from the proximal section to the distal section. The side wall also includes means for conducting fluid within a sidewall of the outer tubular member from the proximal section to the distal section and includes a distal opening positioned to direct fluid at the bur (24) and a treatment site. The inner tubular member (22) is rotatably received within the central lumen. A distal end of the inner tubular member forms a bur extending distally beyond, and exposed relative to, the distal section of the outer tubular member. |
