The utility model discloses a positioning guide device for the puncture of percutaneous vertebral bodies. The utility model is characterized in that the positioning guide device comprises a support frame with two fixing screws capable of being along adjust positions, and a support rod connected with a pair of parallel rods on the support frame through sliding connection. The middle part of the support rod is provided with a positioning screw, and at least one positioning rod is connected with the positioning screw. The utility model also comprises two groups of guide mechanisms positioned at both sides of the positioning screw. Each of the guide mechanisms comprises a guide pipe, an azimuth adjusting device with an outer inclination angle adjusting structure, an azimuth adjusting device with an upper inclination angle adjusting structure, and a fixing structure, wherein the outer inclination angle adjusting structure is provided with an adjusting rotary shaft in the direction parallel to the parallel rods, the upper inclination angle adjusting structure is provided with an adjusting rotary shaft in the direction vertical to the plane of the outer inclination angle and the guide pipe is positioned by the upper inclination angle adjusting structure. The utility model has an artful design and realizes the positioning guiding in puncturing operations of percutaneous vertebral bodies, and imaging monitoring doesn't need to be carried out in the process of needle insertion, so that the influence on doctors and patients is small, the operation safety is enhanced and the operation time is also shortened.
