A rod insertion device (1, 1') for inserting a spinal stabilization rod (95) into at least two bone anchors (901, 901') comprises: a first tubular rod guide (6) configured to guide the spinal stabilization rod (95) therethrough, and a holding device (3, 3') configured to hold the rod guide, an adapter (2) configured to be connected to an extension (9), which is configured to be mounted to a receiving part (90) of the bone anchor (901), and configured to movably support the holding device;
wherein, when the adapter is connected to said extension, the holding device is arranged to move and pivot the rod guide to allow a front portion (64) of the rod guide to be positioned proximal to a rod channel of the receiving part; wherein the holding device includes a clamping portion (5, 5') arranged to clamp a portion (61) of the rod guide, and to allow releasing the portion of the rod guide at least in a state wherein the front portion of the rod guide is positioned proximal to the rod channel of a first receiving part of a first bone anchor, wherein an orientation of the rod guide in the released state may be polyaxially corrected in respect of a second receiving part (90') of a second bone anchor (901'). |
