Thoracoscopic surgery (VATS) is regarded as one of the major breakthroughs in thoracic surgery in the last century. It is a new minimally invasive thoracic surgery technique that uses modern television camera technology and high-tech surgical instruments and equipment to complete complex surgery in the chest wall under a trocar or tiny incision. It has changed the concept of treatment of some thoracic diseases and is considered the most significant progress in thoracic surgery at the end of the 20th century and the future direction of thoracic surgery. It is usually performed under three small 1.5cm incisions, where the surgeon observes the anatomical structures through TV and completes the surgery with special surgical instruments. Compared with the large open surgery doctor’s vision, the doctor’s eyes are located outside the patient’s chest cavity during open surgery, and there is a certain blind spot, while thoracoscopic surgery is equivalent to extending the doctor’s eyes into the patient’s chest cavity for surgical operation, so the operation is more delicate, and the resection can be more thorough for patients with surgical indications; compared with the original large open incision of 30cm, it greatly reduces the trauma of patients and promotes Rapid recovery of patients. At present, we carry out thoracoscopic surgery, including thoracoscopic radical lung cancer surgery, thoracoscopic lobectomy, thoracoscopic segmental lung resection, thoracoscopic radical esophageal cancer surgery, thoracoscopic surgery for severe myasthenia gravis, cardia loss, thoracoscopic mediastinal tumor resection, pneumothorax, hand sweating, etc.
