Abstract: A marker for use in the lung of patients for marking the position of a lesion in the lung, wherein the marker comprises a self-expandable structure capable of self-expanding when released from a constricting device so as to implement marking function. Because the marker for use in the lung of a patient employs the self-expandable structure, when the position of a lesion is detected during a lung examination, the marker can be delivered to the position of the lesion via a catheter or a delivering device and substantively pressed and fixed by the lung when expanded at the lesion positions; as such, the lesion position can be located quickly by a surgeon during a surgery, the surgery time is shortened, the area of resection is reduced, and the post-surgery quality of life is improved for a patient.
