DEVICE AND METHOD FOR MOUNTING INTERVERTEBRAL FUSION CAGE

摘要

PURPOSE: A mount device of an inter-vertebral fusion cage is provided to prevent one pair of fusion cages from being separated from inter-vertebral spaces by forming the direction of screw thread of one pair of fusion cages in the opposite direction. CONSTITUTION: A body unit(100) supports a mounting device of a fusion cage(10). An input shaft(200) is installed in an input hole(110) of the body unit. A handle unit(300) is formed in the upper end of the input shaft. An output shaft(400) is mounted on an output hole(120) of the body unit. A connection unit(500) connects the input shaft and the output shaft with each other. The connection unit includes a rotary shaft(510), a first bevel gear(520) and a second bevel gear(530).
