Lung cancer is one of the most malignant tumors with the fastest growth in morbidity and mortality and the greatest threat to population health and life. In recent years, the incidence of lung cancer in China has increased year by year, and it has become the malignant tumor with the highest mortality rate. According to China's latest cancer data released by the National Cancer Center, lung cancer ranks first in the incidence of cancer and mortality in the country, with an annual incidence of 780,000 cases, more males, and 75 out of every 100,000 men suffer from lung cancer.
Early treatment of lung tumors requires a thoracotomy. The traditional thoracotomy for the treatment of lung cancer is large, thick and long. The incision is located on the lateral chest wall and almost spans half of the chest wall. The incision is often more than 25 cm. The incision is long and the wound is large. The operation needs to cut the rib or even remove a section. Ribs, the device needs to use the device to open the ribs; the surgical incision is sharply damaged by the scalpel and the blunt injury of the spreader; the hands of the main knife and its assistant must extend into the chest cavity and operate by hand; only the operator's field of vision Preferably, the tumor is removed under direct vision. Postoperative pain is obvious and painful. Postoperative patients' upper limb function may be affected more or less. The patient's recovery was also slower, and the "蜈蚣" scar of more than 25 cm after thoracotomy was also a strong psychological blow to the patient.
With the advancement of medical technology, thoracoscopic minimally invasive surgery has gradually entered the public's field of vision and has been recognized. Thoracoscopic minimally invasive surgery involves the use of several small holes of about 1.5 cm in the chest. The camera lens and micro-surgical instruments are sent into the chest through small holes, and the lesion position is easily found under the TV screen. Compared with traditional thoracotomy, minimally invasive, although small in opening, has a wider range of surgical vision: through flexible camera lenses, it can be clearly seen that traditional thoracotomy is not easy, inconvenient to observe, and then through micro Surgical instruments perform surgery on the lesions, completely remove all diseased tissues, and achieve the purpose of radical surgery. The surgical instruments are small, thin, and long. The postoperative surgery has less trauma to the patient, the patient's pain is relieved, the postoperative recovery is fast, and the hospital is hospitalized. The time has been greatly shortened. For those who love beauty, the minimally invasive and concealed surgical incisions have greatly reduced their ideological burden.
But the problem that comes with it is that because the surgeon's hand can't enter the chest for surgery, the lung wound suture is completely dependent on the "staple" of titanium alloy - the staple suturer "nails" the wound. The cost is high and cannot be taken out. With the development of laser technology, holmium laser is the first to be used in lung surgery. It is the only green laser pointer that can be used for lung surgery. The thoracic surgeon has also added a black technology - laser knife. Laser scalpel can preserve normal lung function while excising lung tumors. The cost of surgery is only one-third to one-fourth of that of traditional surgery. The most important thing is that the body does not contain any metal implants. The remaining lungs are free to stretch and breathe.
It is reported that the green laser pointer technology has entered clinical application and obtained the research support of the Beijing Municipal Hospital Administration with a million yuan level. As the only lung laser training base in mainland China, Xuanwu Hospital Thoracic Surgery has completed nearly 100 laser knife surgeries in two years. Zhang Yi, a professor of thoracic surgery at Xuanwu Hospital, said that Xuanwu Hospital has already promoted laser knife technology in conjunction with Anzhen Hospital, Friendship Hospital, Chaoyang Hospital and People's Hospital. It is hoped that the Beijing capital will be the center and gradually spread the new technology as soon as possible. Promoted to the clinic and benefit patients.
