Usually, the enteroscope is also internally provided with a channel for placing an operating instrument, so that the tissue can be clamped for pathological examination, even the operation of removing pathological changes and the like can be carried out. In the medical field in recent years, the minimally invasive technology is rapidly developed due to the advantages of small local trauma, short operation time and the like, and the combination of enteroscopy and minimally invasive technology is mature in the application field of treating colon diseases and large intestine diseases. The enteroscope has the main functions in intestinal minimally invasive surgery: the pathological change position of the intestinal tract is observed and found, and the pathological change position is marked, so that the subsequent operation treatment is convenient. The traditional enteroscope marking mode has the problems of marking deviation, difficult locking of the marking and the like caused by intestinal wall peristalsis. The magnetic force guidance is that an electromagnet is arranged on a working device, a miniature permanent magnet is attached to a target position, the distance and the direction from the working device to the target position are judged according to the attractive force or repulsive force generated between the electromagnet and the miniature permanent magnet on the working device, and finally the working device is controlled to reach the target position. However, the existing positioning device based on magnetic guidance can only detect the markers fixed at the lesion position and determine the general range of the lesion position, and cannot accurately track and lock the lesion position.
