An elongated rotatable surgical cutting instrument having a rotatable cutting element at the distal end of a bendable non-rotating elongated outer member. The instrument enables operation of various cutting devices such as a bendable rotatable burr. In one embodiment the cutting element is rotatably, but irremovably attached to the distal end of the outer member. The proximal end of the cutting element is then releasably attached to the distal end of a flexible coupling which in turn is attached to the distal end of an elongated inner member. The assembly is then rotatably secured within the outer member so the cutting element may be rotated via the inner member. An aspirating lumen extends through the cutting element, the flexible coupling and the inner without detaching the cutting element therefrom. In another embodiment, the cutting element is removable from the outer member when the inner member is removed.
