The invention belongs to a medical tool, and specifically relates to a positioning, guiding and hole-reaming screw tap which is used when medical workers in an operating room operate on a patient. The positioning, guiding and hole-reaming screw tap is composed of a rotary handle and a hollow screw. The positioning, guiding and hole-reaming screw tap is characterized in that the rotary handle is fixed on the upper part of the hollow screw, a core bar is installed in the hollow screw, the bottom of the core bar is processed to form a tip, and the bottom of the hollow screw is processed to form a cutting edge and a screw thread. Because the core bar is installed in the hollow screw and the bottom of the core bar is processed to form the tip, when the screw tap is used, the tip is directed at the spine position of the patient firstly, then the rotary handle is rotated, and the hollow screw enters the spine of the patient. In conclusion, pain of the patient is greatly reduced, the working efficiency of medical workers is greatly improved, and medical accidents are avoided.
