The morbidity and mortality of lung cancer have increased year by year, and lung cancer accounts for the first death of malignant tumors by the end of the 20 th century. The five-year survival rate of lung cancer is only 15%, but if some early lung cancer can be discovered and treated early, the five-year survival rate of the early lung cancer can reach 60-80%. With the development of imaging technology and the popularization of routine physical examination, more and more pulmonary nodules with unknown properties are detected. At present, full thoracoscopic surgery is the main means for diagnosis and treatment of pulmonary nodules, but the precise positioning of the pulmonary nodules in the surgery is difficult to achieve, and the difficulty of the surgery is increased.
The pulmonary nodules (SPN) are the first imaging manifestation of most early lung cancers, and the problem of clinical qualitative diagnosis is becoming more and more prominent. At present, there are various methods for locating pulmonary nodules before thoracoscope surgery, the most common method is location by a steel wire with a hook, but the problems that a locating needle is easy to fall off, pneumothorax is easy to form after puncture, and the like exist. The puncture and sometimes the release are difficult to pull back in the operation process, which increases the difficulty for the operation process of doctors. And once the positioning is not firm, the position is not accurate, the operation time is increased, and even the operation fails.
If can develop a neotype lung nodule not damaged positioner and be used for the isolated tuberculous accurate location before the art of lung, can not only increase the operation security, improve the operation excision rate, still be favorable to further reducing patient medical cost simultaneously, make things convenient for clinical conversion to use and promote, make new technology, new achievement benefit to and extensive SPN patient to the at utmost.
In addition, the positioning of breast micro-tumor, liver tumor, gastric tumor, intestinal polyp and the surgical positioning of pathological tissues of the urinary system all need a novel nondestructive positioning device to perform preoperative accurate positioning, so as to increase the safety of the operation and improve the resection rate of the operation.
Disclosure of Invention
