A surgical cutting instrument including a first tubular member, a second tubular member, a sleeve member, a third tubular member, and an orientation member. The first tubular member includes a cutting tip. The second tubular member has a distal region forming a cutting window. The first tubular member is co-axially disposed within the second tubular member such that the cutting tip is selectively exposed at the cutting window. The first and second tubular members are co-axially disposed within the sleeve member. The third tubular member is co-axially disposed around an intermediate section of the first tubular member, an intermediate region of the second tubular member and the sleeve member. The orientation member is rotatable to transmit a rotational force applied to the orientation member to selectively rotate the second and third tubular members relative to the sleeve member to effectuate spatial rotation of the cutting window.
