VERTICAL CUTTER AND METHOD OF USE

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.
