Methods: The device consists of a sight tube inserted 郑广鹰,男,(1962- ), in a holder, a fixation universal joint, a fixation clamp and a puncture needle, and it has been 本科学历，主任医师。 developed based on the “three-point line” marksmanship principle and the characteristic that the photons of X-ray straight forward propagate. In use, the aiming at channel can be formed 福州市中医院放射科、 when the object achieves three overlaps with far and near ends of sight tube on X-ray machine 福州经济技术开发区医 screen by adjusting sight tube position. Used this fixation device, a puncture needle could be 院放射科，研究方向： more conveniently and accurately inserted into the tube and achieve puncture positioning. Results: Using this device, the successful rate of first puncture positioning of 30 patients X射线空间定位。 reaches up to 95.8% when the operation time for every patient is limited in the first 5 minutes. Conclusion: This device can greatly in
