Background

Lung cancer is the first-ranked malignant tumor at present, and surgical resection is still the main means of treatment. CT has important value for detecting early lung cancer. With the increasing detection of lung tumors in lung nodules, wedge resection of the lung under a television thoracoscope remains the primary means for acquiring the pathology and treatment of lung nodules. But for the small pulmonary nodules with multiple hairs, the diameter of the nodules is less than 1cm, the depth of the nodules is deeper from the pleura of the visceral organs, and the masses are soft in nature, the precise positioning under the thoracoscope is difficult.

Through visual observation, finger touch, supplementary exploration of apparatus in the thoracoscopy, perhaps combine the space imagination to carry out the lung nodule to fix a position according to CT and anatomical positioning point again, the degree of difficulty is very big, often can lead to omitting, is forced to transfer and opens the chest, perhaps enlarges the excision. Therefore, how to accurately position the pulmonary nodules before the operation becomes a problem which needs to be solved urgently at present.

Many approaches have been taken by thoracic surgeons for this purpose. The most widely used method at present is the micro spring coil positioning method. The existing single microcoil positioning method has the defects that the microcoil can not be accurately marked and positioned, so that whether the microcoil falls off or slips off in the operation or not can not be determined, the pulmonary nodules are difficult to accurately position, the operation faces the embarrassing situation that the effective incisional distance is insufficient, even positive, and the pulmonary tissues are required to be cut too much.
