頭顱手術快速立體定位裝置

A rapid 3D positioning device of head surgery is disclosed, which comprises a fine-adjustment component, a positioning component, and an alignment component. The fine-adjustment component is for mounting a needle, and can finely adjust the needle to proceed the linear movement. The positioning component is fixed at a target object, and can move together with the fine-adjustment component to proceed two rotation axial movements. The alignment component is for aligning and fixing the overall structure of the fine-adjustment component and the positioning component at the incision of the skull. Thus, when the target object is the skull, the overall structure can be accurately aligned at the center of circle of the incision on the skull, the positioning component can be applied to adjust the fine-adjustment component to aim at the correct position, and the fine-adjustment component can shift the needle, so as to rapidly assist the precise positioning of the head surgery, and further achieve the purpose of enhancing the convenience and simplicity for the surgery.
