Intervertebral fusion device arranged on vertebral endplate of two vertebraeIn between, the fusion device includes a hollow body and a filling body, wherein at least one surface of the hollow body is provided with an opening, and the hollow body further includes an implanted front end and an implanted rear end. The upper surface and a first lower surface are respectively provided with a first stopper； the second upper surface and the second lower surface of the implanted rear end are respectively provided with a second stopper； the filling body is disposed in the hollow Within the body, the filling body is provided with a plurality of holes, a first thickness of one of the implanted front ends is smaller than a second thickness of the hollow body, and the implanted front end has a circular arc structure, and the fusion is increased by the above structure. The fixing and stability of the device improves the cell attachment ability, increases the contact area between blood and the implant, promotes the growth of bone cells into the implant, and solves the problem of the instability of the fusion device.一種椎間融合裝置，其設置於二脊椎之椎體終板之間，該融合裝置包含一中空本體及一填充體，其中該中空本體至少一表面設有一開口，該中空本體更包含一植入前端及一植入後端，該植入前端之一第一上表面及一第一下表面分別設有一第一限位件；該植入後端之一第二上表面及一第二下表面分別設有一第二限位件；該填充體設置於該中空本體內，該填充體設有複數個孔洞，其一植入前端之一第一厚度小於該中空本體之一第二厚度，並且該植入前端為圓弧結構，藉由上述之結構增加了融合裝置的固定穩定力，提高了細胞貼附能力，增大了血液與植入物的接觸面積，促進了骨細胞向植入物內生長，解決了融合裝置不牢固的問題。
