Abstract
A cutting accessory for use with a powered surgical tool includes an elongated outer tube with an outer hub attached to the proximal end for releasably securing the cutting accessory within the powered tool. An elongated inner member is received within the outer tube and has an inner hub adapted to be driven by the surgical tool. The dimensions of the outer tube and inner member are such as to form an annular channel therebetween for the passage of irrigating fluid. The inner member carries a cutting tool, such as a burr, at its distal end, the tool being accessible through an aperture in the outer tube. A bearing member is located in the annular channel between the inner member and the outer tube, and a bypass channel runs external to the outer tube to carry irrigating fluid to the cutting tool bypassing the bearing member. An aperture through the outer tube connects the annular channel with the bypass channel.
