Abstract
An apparatus for inserting an intervertebral fusion cage includes a dilatation set, a guiding set and an insert set. The dilatation set includes first and second dilatation barrels non-rotationally and telescopically connected to each other. The guiding set includes first and second guiding tubes provided around the first and second dilatation barrels. The second guiding tube includes a guiding hole defined therein and a smooth arched face formed thereon in the guiding hole. The insert set includes a leading rod inserted in the second guiding tube and a push rod pivotally connected to at the leading rod. The intervertebral fusion cage is located in the second guiding tube. The fusion cage is movable out of the second guiding tube along the smooth face and the guiding hole to shorten surgery time and position the fusion cage precisely.
