This creation is a kind of opening device.Including: first upper fixing part,A fixed part and an elastic part,The outer surfaces of the upper fixing part and the lower fixing part are respectively convex with a U-shaped convex part.At least one sharp convex part is convex on the relative inner surface of the upper fixed part and the lower fixed part；In this way,The upper fixation part and the lower fixation part are respectively locked on both sides of the spinous process of the vertebrae.And the sharp convex part is firmly combined with the vertebrae.The elastic part supports the interspace between the spinous processes of the vertebrae.To treat the patients with intervertebral stenosis and abnormal connective tissue of intervertebral disc,The elastic part can bear compression.Stretching and twisting,Each U-shaped convex part has the function of auxiliary removal.And then make this creation improve the practicality of spine treatment.本創作係一種撐開裝置，包括：一上固定部、一下固定部及一彈性部，該上固定部及該下固定部的外側面分別凸設一U形凸件，該上固定部和該下固定部的相對內面凸設至少一尖凸部；藉此，該上固定部和該下固定部分別鎖固於脊椎骨的棘突兩側，並將該尖凸部牢固地與脊椎骨結合，使該彈性部支撐脊椎骨棘突之間隙，以治療患者椎間狹窄與椎間盤的結締組織異常，該彈性部可承受壓縮、拉伸及扭轉動作，各該U形凸件係具輔助移除之作用，進而使本創作提升脊椎治療上的實用性。
