The present invention proposes an implantation instrument for an intervertebral fusion device, which includes a clamping base for clamping the intervertebral fusion device, a connecting rod group connected to the clamping base, and a sleeve sleeved outside the connecting rod group. The clamping seat includes an arc-shaped surface and a plurality of clamping members each having a corresponding connecting portion. The link group includes a plurality of connecting rods each having a connecting portion, and the plurality of connecting rods are clamped by the respective connecting portions and a plurality of clamping portions. The corresponding connections of the pieces are connected. Operate one of the connecting rod groups to make the curved surface of the clamping seat and the sleeve tight, so as to drive the interbody fusion cage fixed on the clamping seat to rotate between the vertebral bodies, or cooperate with the operating connecting rod group The other connecting rod makes the clamping seat rotate more, which in turn drives the interbody fusion cage to rotate between the vertebral bodies.本案提出一種用於椎間融合器之植入器械，包括：夾持椎間融合器的夾持座、連接組裝於夾持座之連桿組以及套設在連桿組外之套筒。夾持座包括一弧形面以及各自具有相應連接部之複數個夾持件，連桿組包括各自具有連接部之複數個連桿，且複數個連桿以各自的連接部與複數個夾持件的相應連接部連接。操作連桿組的其中之一連桿以使夾持座的弧形面與套筒迫緊，以帶動固定在夾持座上的椎間融合器於椎體間旋轉，或者配合操作連桿組的其中之另一連桿，使得夾持座產生更大的轉動，進而帶動椎間融合器於椎體間旋轉。
