    摘要： A detachable vertical cutter for insertion into a cylinder or tube is formed as a single unitary structure. The single blade has a pair of tool attachment end portions and a cutting blade extending in a loop between the attachment ends. The cutting blade is inclined vertically relative to a longitudinal axis of a cylinder or tube into which the attachment ends can slide into. The cutting blade has a cutting edge, a portion of which when extended free of the cylinder or tube will extend a distance greater than the tube outside diameter. The cutting edge when pushed inwardly and pulled outwardly between adjacent vertebrae scrapes and cuts disc material. When retracted the cutting blade deflects into the cylinder or tube for insertion or extraction into or from the disc space.

    摘要： An apparatus suitable for cleaning a surgically prepared bony concavity includes a body portion adapted to supply pressurized fluid (preferably carbon dioxide gas) to the concavity and aspirate surface debris. The apparatus further comprises a head having an orifice with a plane, circular rim having a diameter less than that of the bony concavity. A method for cleaning a surgically prepared, concave, generally hemispherical bony cavity includes the steps of: covering a region of the hemispherical bony concavity with a cleaning head; supplying a pressurized fluid to the region covered by the cleaning head, and collecting the pressurized fluid from the covered region with a surface debris aspirator coupled to the cleaning head. A cleaning head having a generally circular orifice substantially seals and encloses a spherical zone to be cleaned.
