Puncture positioning navigation method and device and electronic equipment

The invention provides a puncture positioning and navigation method and device and electronic equipment, and relates to the technical field of surgical navigation.The puncture positioning and navigation method comprises the steps that model construction processing and operation planning processing are conducted on a CT image of a patient, and a human organ model and initial surgical planning information in the human organ model are determined; human body coordinates of a patient, probe coordinates of a puncture needle and probe coordinates of an ultrasonic probe in ultrasonic equipment are obtained through optical positioning equipment; and determining planned path adjustment information by using the ultrasonic equipment, and performing data updating processing on the initial surgical planning information according to the planned path adjustment information, the human body coordinates, the probe coordinates and the probe coordinates to determine target surgical planning information. According to the method, r
