CT GUIDED PUNCTURE POSITIONING GRID FOR EASY POSITIONING

The utility model discloses a CT guiding puncture positioning grid easy to position, which comprises two limiting strips and a plurality of CT developing positioning wires, the plurality of CT developing positioning wires are arranged between the two limiting strips in parallel, two ends of each CT developing positioning wire are respectively fixed with the two limiting strips, a plurality of sections of developing core materials which are arranged in sequence are arranged in the CT developing positioning wires, and the developing core materials are arranged in parallel. The sections of the developing core materials are different in shape, and marks corresponding to the sections of the developing core materials are marked on the surfaces of the developing positioning wires. When the positioning grid is used, the limiting strip is attached to the specific skin of the human body, during CT scanning, the developing core material is developed in a CT picture, the corresponding position on the positioning grid can be visually read according to the section shape displayed by the developing core material, and the corresponding mark of the positioning grid can be read according to the tumor puncture position; compared with the existing positioning grid, the positioning of the positioning grid is convenient and accurate, and the time is saved.
