The invention discloses an infrared ray navigation tool. The infrared ray navigation tool comprises a bracket, two perspective plates which are fixed on the bracket and perpendicular to each other, and an infrared ray projection device. The infrared ray projection device comprises two infrared ray emitters respectively matched with two perspective plates. During the puncture surgery, two perspective plates are respectively in parallel to a vertical plane and a coronal plane of a patient's body. Medical workers respectively mark projections of target puncture lines of two perspective plates by using a C arm machine in positive position and side position; and then forms a straight line in vitro by using the infrared projection device according to the principle of determining a straight line by two intersected faces; subsequently, the medical workers fix a puncture sleeve and overlap it with the straight line by using the sleeve fixing bracket; the puncture sleeve is fixed by the sleeve fixing bracket, so as to prevent the deviation during the surgical operation.
