The invention relates to a spinal internal fixation sight, which comprises an arc-shaped guide rail, an arc-shaped sliding unit combined with arc-shaped guide rail movement, and a tool fixing seat arranged on the arc-shaped sliding unit, which can be fixed after moving to a predetermined position.Therefore, the arc guide rail can be fixed on the operating table, and the angle between the arc sliding unit and the tool fixing base can be adjusted properly according to the needs of the operation process. When the surgeon uses the arc guide rail and the arc sliding unit to adjust, the tool fixing base can be fixed into the nail point in the spine of the surgical patient at each moving angle, so as to achieve It is easy to operate and accurately align.本創作係一種脊椎內固定瞄準器，其包含有一弧型導軌；一與弧型導軌活動結合之弧型滑動單元；以及一設於弧型滑動單元上之工具固定座，而該工具固定座可於移動至預定位置後予以固定。藉此，可於使用時，將弧型導軌固定於手術台上，並令弧型滑動單元與工具固定座依手術過程所需而進行適當角度之調整，當手術醫師用以調整時，係透過弧型導軌與弧型滑動單元之配合，使工具固定座於各移動角度皆可對應手術患者之脊椎內固定入釘點，進而達到易於操作與準確對位之功效。
