The invention discloses a puncture guiding device. The puncture guiding device is configured to guide the correct linkages to be disposed inside an accommodate seat of a pedicle screw locked to the spinal in order to limit a relative distance of the corresponding spinal. A height of each pedicle screw drilled on the spinal can be adjusted by the correct linkages according to a radian of the correct linkages. An accommodating parts of each pedicle screw are punctured by the correct linkages that is guided by the guiding device to limit a relative distance of the corresponding spinal.本發明揭露一種穿刺導引器,係用以將矯正連桿置放並鎖固於脊柱之椎弓根釘的容置座內,以拘束相對應脊柱之相對距離。此穿刺導引器包含拉桿、導引套筒、導引臂及夾持部,其中可藉由矯正連桿之弧度以適應性調整導引套筒之第一調整單元及導引臂之第二調整單元,以提升手術的準確性及成功性。100‧‧‧穿刺導引器10‧‧‧拉桿11‧‧‧握把12‧‧‧螺紋結構20‧‧‧導引套筒21‧‧‧卡合部211‧‧‧卡榫結構22‧‧‧樞軸23‧‧‧卡扣環30‧‧‧導引臂31‧‧‧擺動桿32‧‧‧弧形桿321‧‧‧滑槽33‧‧‧橈性推桿38‧‧‧操控部40‧‧‧夾持部
