Inclusion criteria
Inclusion criteria: (1)Age>= 18 years old and < 80 years old, gender not limited; (2)Patients who require preoperative localization of pulmonary nodules and meet any of the following criteria can be included in the study: a)Solitary peripheral nodules in the lungs with a diameter of less than 1cm and a tumor distance of more than 1.5cm from the lung edge; b)Imaging manifestations include pure ground glass nodules or sub solid nodules; c)Surgical personnel who have difficulty locating intraoperative nodules before surgery; (3)The patient fully understands the benefits and risks of this trial, is willing to participate in this trial, and signs an informed consent form.
Exclusion criteria
Exclusion criteria: (1)Patients with skin redness, swelling, damage, symptoms of skin diseases, inability to stick markers for skin diseases, or acute suppurative infections in the pleural cavity at the puncture site; (2)Irreversible coagulation dysfunction or significant abnormalities in coagulation function; (3)Pulmonary nodules are located in the scapular region that obstructs percutaneous localization; (4)Pulmonary nodules located near important organs such as mediastinum or large blood vessels in the heart; (5)After the first CT scan for localization, new changes were found in the patient's target lung nodules, such as decreased or disappeared lung nodule density, or the appearance of new lesions in the lungs, such as hospital acquired pneumonia (HAP), pneumothorax, etc., which may affect subsequent localization operations; (6)Patients with pneumothorax caused by other diseases such as pulmonary bullae or pulmonary cysts in the proposed puncture path; (7)There are obvious infectious lesions on the puncture path; (8)Anatomical or functional isolated lung; (9)Critical patients with severe heart, liver, lung, and kidney dysfunction: (10)Unable to cooperate, unable to control coughing, unable to tolerate puncture; (11)Pregnant or lactating women, as well as others who cannot receive intraoperative radiation; (12)The patient's scheduled surgery has been temporarily cancelled; (13)Individuals who have participated or are currently participating in other clinical trials within the 28 days prior to screening; (14)Researchers evaluate subjects with poor compliance or other reasons who are not suitable to participate in this trial.
