Background
With the development and popularity of CT (Computed Tomography, also known as Computed Tomography) as a screening technique for breast physical examination, the detection rate of small pulmonary nodules, particularly ground glass nodules, has seen explosive growth. After the small pulmonary nodules are detected, the small pulmonary nodules are determined to be benign nodules, and surgical excision is not needed; those nodules of highly suspected malignant tumors are resected by thoracoscopic minimally invasive surgery. Failure to locate means that the patient needs to transfer to the chest, do unnecessary lobectomy, and may even miss the lesion. If accurate localization of nodules is possible, only a small range of resection is required for lung cancer in the sprouting state, and the patient can retain lung function. The palpation failure rate of the nodules with the diameter of less than 10mm and more than 5mm is higher than 50%, the nodules with the diameter of less than 5mm are difficult for doctors to find the focus rapidly by naked eyes or hand feeling, and currently, the breast nodule locating needle is generally used for locating the breast nodules clinically, so that the breast nodule locating needle is used for locating the lung nodules, and the locating needle uses barbed metal wires for locating, so that the risk of causing trauma to the lung is very high.
