Abstract
A surgical tool for resecting bone includes a pneumatic motor to which a bearing tube is secured for rotatably supporting a resecting tool. The bearing tube is eccentrically disposed within an attachment tube, with a flow channel defined between an interior of the attachment tube and an exterior of the bearing tube. Irrigation fluid is passed through the flow channel to maintain a constant flow of irrigation fluid about a cutting end of the resecting tool. Optical fibers extend within the attachment tube for passing light to lenses disposed at the specimen end of the attachment tube for providing illumination. At least one optical fiber extends from a lens at the specimen end, through the attachment tube, and to an optical viewer for providing a means for inspecting the bone being resected. The attachment tube is slidably adjustable along the bearing tube for selecting a distance between the specimen end of the attachment tube and the cutting end of the resecting tool.
