    摘要： A surgical instrument includes a main unit and a suction conduit. The main unit includes at least one tubular body having a distal end, a proximal end, and an inlet disposed near the distal end. The suction conduit is slidably disposed over the main unit, and is slidably movable along the main unit between a retracted position, at which the suction conduit does not cover the inlet of the main unit, and an extended position at which the suction conduit covers the inlet of the main unit and a suction inlet of the suction conduit is placed in fluid-communication with the main unit inlet. The surgical instrument can be used as a suction tool by placing the suction conduit in the extended position and applying a vacuum through the inlet of the main unit and the suction inlet.

    摘要： A surgical instrument includes a hollow tubular member having a closed distal working end, a proximal end and an outer surface, with an opening in a side wall at or adjacent the distal working end. The instrument includes a first electrical insulation layer disposed on at least part of the outer surface of the hollow tubular member, a first electrode disposed on an outer surface of the first electrical insulation layer, and a second electrode disposed on the outer surface of the first electrical insulation layer. The first and second electrodes are electrically isolated from each other, and each includes an active segment and an inactive segment. The active segments of the first and second electrodes are disposed respectively on opposing sides of the hollow tubular member preferably within about 3.0 mm of the opening in the side wall of the hollow tubular member.

    摘要： A surgical instrument includes first and second cutting blades, each including a tubular body having proximal and distal ends, with a cutting window disposed at a side of each cutting blade near its distal end. The second cutting blade rotates within 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. An area of the first cutting blade suction aperture is smaller than an area of the second cutting blade suction aperture. The instrument is used as a suction tool 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 to apply the vacuum through the suction apertures.
