Usually, lung cancer patients undergoing lobectomy need to make an incision of about 25-30 cm in length on their chest wall, cut off multiple layers of muscles, and sever or remove part of the ribs, which causes severe postoperative pain and requires painkillers and long recovery time. Postoperative resistance to disease is significantly reduced, and the quality of life is significantly reduced. Minimally invasive surgery —- has completely solved this problem, bringing hope to patients who are afraid of open-heart surgery or cannot tolerate it. The surgery is performed by making only two small 1-1.5 cm holes and a small 3-4 cm incision in the patient’s chest, and the entire intra-thoracic surgical operation is performed outside the chest by viewing a TV screen with thoracoscopic outreach, without the need to cut off muscles and ribs. It is a minimally invasive surgery in the true sense of the word because it is less traumatic, less painful, faster recovery, more effective and aesthetically pleasing. Compared with conventional open-heart surgery, thoracoscopic surgery for lung cancer has no difference in complete resection of tumor, complete lymph node dissection and long-term survival rate after surgery, and most reports are even better, and the rate of intraoperative and postoperative complications is significantly reduced. It is a kind of radical surgery for lung cancer recognized by international academic circles and is a very safe surgical procedure. It is especially adapted to the treatment of patients with early-stage lung cancer and peripheral type lung cancer. Thus, minimally invasive surgery —- full thoracoscopic surgery for lung cancer has brought a real blessing to patients.
