    摘要： A surgical instrument has a hollow tubular member, and a pressurization unit that has an outer valve portion, a pressurization device having a movable part configured to generate pressurized fluid when the movable part is moved, and an inner valve portion. The inner valve portion includes a first flow passage that is configured to connect a first port and a second port of the outer valve portion to each other when the inner valve portion is in a first position, and a second flow passage that is configured to connect the first port of the outer valve portion to the pressurization device when the inner valve portion is in a second position. Pressurized fluid from the pressurization device causes the inner valve portion to move from the first position to the second position, thereby providing positive pressure to the hollow tubular member.

    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.

    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.
