Zusammenfassung:A rotatable surgical instrument and method includes an outer tubular member and an inner tubular member contained, at least in part, within the outer tubular member and configured to rotate relative to the outer tubular member, the inner tubular member and outer tubular member forming a gap therebetween. A distal tip is coupled to and configured to rotate with the inner tubular member. Bearings, each positioned in the gap and encircling the inner tubular member, are configured to maintain a separation between the outer tubular member and the inner tubular member. A spacer is positioned within the gap and between two of the bearings, wherein the spacer is configured to maintain a spacing between the bearings.
