1. A method of using a surgical cutting instrument, comprising:
grasping a surgical cutting instrument, the instrument including:
a first tubular member having a cutting tip,
a second tubular member having a cutting window, wherein 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,
a sleeve member wherein the first and second tubular members are co-axially disposed within the sleeve member,
a third tubular member, wherein the sleeve member is co-axially disposed within the third tubular member, and
an orientation member frictionally fit over the sleeve member and rigidly secured to the third tubular member, wherein the orientation member is rotatable to transmit a rotational force applied to the orientation member to rotate the second tubular member to effectuate spatial rotation of the cutting window;
positioning the cutting window and cutting tip at a target tissue;
rotating the cutting tip to selectively cut the target tissue in a first area;
maintaining the cutting tip at the target tissue; and
rotating the orientation member to selectively reposition the cutting window to expose the cutting tip to cut the target tissue in a second area.
