With the development of surgical technology and anesthesia technology, pulmonary nodule surgery has developed to the era of "minimally invasive", and some early pulmonary nodules can be "day surgery", but patients who have undergone radical surgery for pulmonary nodules still complain of pain, why is this?
In fact, it is not the surgical process that hurts, but the process of positioning and puncture before surgery - percutaneous puncture is an invasive surgical operation, which can be called "painful surgery itself".
Other positioning techniques include magneto-guided transbronchial positioning, which is not painful but is more damaging to the bronchial lining and may result in partial atelectasis after surgery.
In order to solve the problem of surgical positioning, the team of Professor He Jianxing of the National Respiratory Medicine Center of the First Affiliated Hospital of Guangzhou Medical University independently developed a "painless and non-invasive positioning technology" with mixed reality effect based on the idea of "metaverse" mixed reality, so that doctors can become "see-through eyes", and patients can achieve accurate resection of complex and multiple pulmonary nodules without going through preoperative puncture or bronchial positioning.

Ms. Zhang and Mr. Li are the beneficiaries of this new technology.
A 28-year-old Ms. Zhang was found to have a ground-glass opacity with a diameter of 8 mm on the medial side of the middle lobe of her right lung, which was highly suspicious of malignancy and required surgical resection. A friend who has had surgery told her that the operation is not difficult, but the preoperative puncture positioning is more painful than the surgery. This couldn't help but make the young Miss Zhang panic.
Mr. Li, 50, is also worried about lung nodules – his lung nodules are more than 1 centimeter in diameter and are located in a "tricky" location, which is very difficult to locate and risks damaging the diaphragm. The local doctor recommended a lobectomy directly, but it was bound to have an impact on his later life.
In order to find a better solution, the two came to the National Respiratory Medicine Center of the First Affiliated Hospital of Guangzhou Medical University.
Professor He Jianxing's team applied the "Metaverse Painless and Non-invasive Positioning Technology" to solve the problem of preoperative puncture and positioning of the two patients, and the lesions were successfully removed in only ten minutes during the operation, and the pathological results showed that they were both early stage lung cancer.
According to reports, the "Metaverse painless and non-invasive positioning technology" includes 3D reconstruction imaging technology, multi-person multi-view naked-eye 3D display system and naked-eye 3D thoracoscopic display system.
Among them, 3D reconstruction imaging technology can reconstruct the relevant structures of the lung through the patient's chest CT image before surgery, so as to achieve painless and non-invasive accurate positioning of the size, shape, location and three-dimensional relationship with bronchi, artery and vein of the pulmonary nodule.
The multi-person multi-view naked-eye 3D display system and naked-eye 3D thoracoscopic display system allow the surgeon to become a "see-through eye", and the location of the lesion can be seen at a glance without wearing other receiving equipment during the operation, so as to accurately delineate the scope of the operation, so as to achieve "neither more incision, but not too much incision", even if the lung nodule in a tricky position can be "pulled out", to avoid trauma to normal lung tissue to the greatest extent.
"It is equivalent to pushing the target directly in front of you, and hitting it with one hit, which is a very accurate 'targeted elimination technique'. "The team is introduced.
With the development of detection technology
At present, the detection rate of pulmonary nodules is increasing
What needs to be surgically managed?
"Painless and non-invasive positioning technology in the metaverse"
What types of pulmonary nodules are used?
"More than 95% of lung nodules found through physical examinations or lung cancer screening programs are benign. The team recommends:
◎ If the nodule is smaller than 7 or 8 mm, surgical treatment is not required for the time being, and the CT can be re-examined after 3 months to half a year.
◎ If the examination finds that the nodule does not appear to increase significantly, the observation can be continued, and the re-examination period can be extended to about half a year to one year.
◎ When the re-examination finds that the nodule becomes solid or enlarged, it indicates that there is an increase in local cells and there is a possibility of malignancy, and it is recommended to have a radical cure by surgery.
◎ If the nodule is larger than 7 or 8 mm, and the benign or malignant nature cannot be determined temporarily, then prescription antibiotics can be used for anti-inflammatory first, and whether the next step of treatment is necessary according to the changes in the nodule.
This "painless and non-invasive positioning technology" helps to improve the safety and accuracy of surgery, shorten the operation time, and accelerate postoperative recovery, and is suitable for radical surgery such as ordinary pulmonary nodules, small pulmonary nodules, and complex multiple pulmonary nodules.
