The present invention relates to a screw positioning device, which mainly includes a grip portion, a neck and a positioning portion； wherein the neck is connected to one end of the grip portion, and the positioning portion includes a first side plate, a second side plate and a bottom plate, the bottom plate It is connected to the neck and extends from the upper surface of the grip portion to a specific angle； the first side plate and the second side plate are connected to two corresponding sides of the bottom plate, and are involute toward the direction away from the bottom plate. According to this, the positioning portion can be erected on the vertebral bone, and the bottom plate is pressed against the upper edge of the vertebral bone, and the first side plate and the second side plate are respectively abutted on the two sides of the vertebral bone, thereby forming a fairly stable Positioning effect； however, the grip and neck can form a guide. As long as the screw is aligned with the orientation of the grip and neck, it can ensure that the screw is implanted in the correct orientation without deviation.本新型係有關於一種螺釘定位裝置，主要包括握持部、頸部及定位部；其中，頸部係連接於握持部之一端，而定位部包括第一側板、第二側板及底板，底板係連接於頸部並自握持部之上表面朝一特定角度延伸；第一側板及第二側板係連接於底板之二相對應側，且朝背離底板方向呈漸開狀。據此，定位部可架設於椎節骨上，而底板壓靠於椎節骨之上緣，第一側板和第二側板則分別貼靠在椎節骨之二側面，藉此形成相當穩固的定位效果；然而握持部和頸部便可構成導引部，螺釘只要對準握持部和頸部之方位植入，便可確保螺釘植入正確方位，不會產生偏移。
