Surgery is the first choice and the most important treatment for lung cancer. Lung cancer surgery is moving toward minimally invasive to minimize patients’ pain, and the use of TV thoracoscopic minimally invasive surgery technique for lung cancer has become a mature and routine treatment method. Minimally invasive surgery is to make several small holes of about 1.5cm in length in the chest, send camera lens and micro surgical instruments into the chest through the small holes respectively, easily find the location of the lesion under the TV screen, perform surgery on the lesion and completely remove all the diseased tissues to achieve the purpose of radical surgery, and the wound only needs to be closed with absorbable sutures or put on a band-aid, which is a new thoracic surgery method. This is a new thoracic surgery method, TV thoracoscopic minimally invasive treatment technique. The advantages of thoracoscopic minimally invasive surgery for lung cancer are very prominent. Thoracoscopic surgery is less traumatic for patients, faster recovery, better surgical results and shorter hospital stay. In a word, it is safe, simple and effective. 1, small trauma: thoracoscopic surgery incision is only about 1.5 cm, so the surgery is small trauma, compared with the conventional surgery 30 cm incision can significantly reduce the patient’s pain and surgical danger; small trauma, the relative chance of infection is also less; thoracoscopic small incision surgery for the patient’s postoperative lung function damage is small, can maintain and improve the quality of life of patients. 2.Light pain: The small incision avoids pulling open the ribs and does not cut off the ribs, which reduces the pressure on the nerves and avoids the friction of the broken ends of the ribs, so the postoperative pain of patients is significantly reduced compared with the traditional incision. 3.Wide field of view: Compared with traditional open-heart surgery, minimally invasive has a broader surgical field of view although the opening is small: through the flexible camera lens, it is possible to clearly see the places that are not easily and conveniently observed in traditional open-heart surgery, and then operate on the lesions through microsurgical instruments to completely remove all the diseased tissues and achieve the purpose of radical surgery. 4.Fast recovery: Because the small incision does not cut off the large muscles of the chest, does not cut off or hold open the ribs, does not pull the scapula, so the muscles and bones of the motor system are not traumatized, and the function of shoulder joint activities is affected little and recovered quickly. 5.Beautiful incision: It is especially important for people who love beauty, that is, the incision will not be so obvious because it is too big. 6.Low overall cost: Due to minimally invasive surgery equipment and materials, the cost of surgery may be slightly higher than that of open-heart surgery, but the overall cost of minimally invasive surgery is not too high, even lower than that of ordinary open-heart surgery due to short hospitalization time, fast recovery, less medication and fewer complications. Minimally invasive surgery compared with traditional surgery Minimally invasive surgery for lung cancer can achieve the same effect as open-chest surgery, or even better. The TV display during the operation greatly increases the surgeon’s “vision”, “field of vision” and The TV display during the operation greatly increases the surgeon’s “vision”, “field of view” and “line of sight”, so that the lesion can be clearly displayed on the TV and histopathological examination can be obtained, resulting in more accurate surgical operation and higher surgical quality. III. Which patients are suitable for minimally invasive surgery With the accumulation of experience and advancement of technology, minimally invasive surgery is now more and more widely applicable, and in fact suitable for most lung tumor patients. 1. It has been the consensus and common practice of domestic and foreign thoracoscopic experts to give priority to thoracoscopic surgery for all early-stage lung cancer. 2.Most patients with mid-stage lung cancer can be completely and radically resected under minimally invasive thoracoscopic surgery. 3.Some advanced lung cancers are also within the scope of indications. 4.Surgical resection of metastatic lung cancer. 5.Almost all benign lung tumors. 6.Minimally invasive surgical treatment is of great significance, especially for the elderly and patients with poor lung function who can hardly accept traditional open-heart surgery.
