Abstract

The invention provides a technical scheme of threaded fusion cage. The threaded fusion cage comprises a fusion body and a push rod which is arranged in the fusion body and is axially connected with the fusion body in a threaded manner. The threaded fusion cage is characterized in that the vertical projection of the fusion body is a chamfered rectangle, the upper portion of the fusion body is a base portion while the lower portion is a head portion, and an integral structure of an inverted-tooth portion is arranged between the base portion and the head portion; the inverted-tooth portion is provided with a front inverted-tooth wall and a back inverted-tooth wall, two side walls are lacked, and corresponding inverted-tooth wall holes are formed in the two inverted-tooth walls; the head portion is an inverted trapezoidal platform, parallel head openings of the two inverted-tooth walls are formed in the bottom surface of the head portion, and both sides of the head opening in the inner wall of the head portion are inclined planes; a push rod transverse hole penetrating the push rod is formed vertical to the axis of the push rod in the middle lower portion of the push rod, and a push rod axle hole which is connected with the push rod transverse hole is formed along the axis of the push rod in the top end of the push rod.
