摘要：A surgical instrument includes first and second cutting blades, each including a tubular body having a proximal end and a distal end, with a cutting window disposed at a side of each cutting blade near its distal end. The second cutting blade rotates inside of the first cutting blade to cut tissue while a vacuum is applied through an internal bore of the second cutting blade. The distal end of each of the cutting blades includes a suction aperture through which a longitudinal axis of the cutting blades extends. The surgical instrument can be used as a suction tool in which the vacuum is applied through the suction apertures by applying the vacuum through the internal bore of the second cutting blade while the second cutting blade is stopped from rotating with the cutting windows of the first and second cutting blades misaligned with each other.
