CT-guided pulmonary nodule puncture angle positioning device

The invention discloses a CT-guided pulmonary nodule puncture angle positioning device, which relates to the technical field of medical puncture auxiliary instruments and comprises a connecting mechanism, an adjusting mechanism, an original point orientation mechanism and a puncture orientation mechanism, a connecting mechanism, an adjusting mechanism, an original point orientation mechanism and a puncture orientation mechanism are arranged, the adjusting mechanism, the original point orientation mechanism and the puncture orientation mechanism are connected with a CT puncture bed through the connecting mechanism, and the adjusting mechanism is used for adjusting the position of the original point orientation mechanism to position an original puncture point, located on the same straight line with a pulmonary nodule, on a CT machine. The puncture orientation mechanism is matched with the original point orientation mechanism and coincides with the straight line where the determined puncture point finally determ
