An elastic spine fusion device includes: a fusion device having a head and a tail； a peripheral surface of the fusion device is provided with an uninterrupted spiral structure to provide elastic buffering, and the ends of the spiral structure are respectively stopped On both sides of the tail, the line segments formed by the helical structure are parallel to each other, and an adjustment channel that passes through the helical structure and runs through the fusion device； when the fusion device is placed between the spines, it has a decompression effect Stress can be eliminated, and the spiral structure can increase the tolerance and stability of the fusion device.一種彈性脊椎融合裝置，包括：一融合裝置具有一頭部及一尾部，該融合裝置的周面環設一不間斷的螺旋狀結構以提供彈性緩衝，該螺旋狀結構的首末兩端分別止於該尾部兩側，且該螺旋狀結構所形成的線段皆相互平行，及一穿經該螺旋狀結構並貫設該融合裝置的調整孔道；當該融合裝置設置於脊椎間時具有減壓作用能排除應力，此外該螺旋狀結構能增加該融合裝置的承受度及穩定性。
