  • Laparoscopic surgical instruments for incision of the lesion may be inserted in the other two holes.
  • the present invention there is an advantage that it is easy and accurate from the process of displaying the location of the patient's body lesion to the tracking process, and the production is easy by forming a portion of the clip that is bound to the lesion for magnetic marking the location of the lesion It is advantageous in miniaturization.
  • the operation time is shortened, the magnetic body of the clip is detected from the outside without the incision for tracking the location of the lesion, the location of the lesion is tracked and the incision for the operation is performed. Scars are reduced.
  • the present invention relates to a lesion position marking clip and a lesion position tracking system and method using the same, and more particularly, to a lesion position marking clip made of at least a portion of a magnetic material and a system and method for tracking a lesion position using the same. will be.
