Detection method of magnetic positioner in tissue focus and use method of detection device

The invention discloses a detection method of a magnetic locator in a tissue focus and a use method of a detection device of the magnetic locator, and relates to the technical field of detection. The detection device comprises a detection rod used for entering a human body cavity, and the detection rod is provided with a magnetic sensor; the magnetic attraction body is arranged at the front end of the detection rod and is used for attracting the magnetic positioner; the main control unit is connected with the magnetic sensor; the signal sending unit is connected with the main control unit and used for sending a feedback signal to the outside; the detection method specifically comprises the steps of calibration, detection, data analysis, data selection and data feedback, so that the position of the magnetic locator is rapidly detected. Compared with the prior art, the system has the advantages that the magnetic sensor is used for sensing the magnetic positioner in a tissue focus to rapidly detect the position
