Minimally invasive thoracic surgery is the pinnacle of the development of thoracic surgical techniques in the 21st century, and thoracoscopic lobectomy is one of the typical procedures of minimally invasive thoracic surgery. The advantages of thoracoscopic lobectomy are mainly reflected in the following aspects: 1. The surgical incision is small and minimally invasive, generally using three keyhole-sized incisions, which is aesthetically pleasing and more convenient for patients to receive surgery. 2, to achieve the same degree of lymph node dissection as open surgery. 3.The magnification imaging system enables the operator to operate the surgical instruments more finely and accurately. 4.Less intraoperative bleeding, reducing the trauma of blood loss to the organism, truly reaching good blood protection, and generally little blood transfusion. 4.Light pain, small incision, natural gap into the chest cavity, no use of rib spacers. 5.The postoperative lung function is less impaired, which improves the scope of application of the operation. It provides surgical treatment opportunity for a part of early stage lung cancer patients with advanced age and high risk factors. 6. Better quality of life in the long term. Shortening hospitalization time and low incidence of postoperative complications can improve the survivability of elderly patients and high-risk patients after discharge from hospital. Internationally, after years of clinical evidence, it has been confirmed that thoracoscopic radical lung cancer surgery is safe, minimally invasive, with faster recovery and higher long-term survival rate than open surgery, and has become the standard procedure for the treatment of early-stage lung cancer.
