Thoracoscopic surgery 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 TV camera technology and high-tech surgical instruments and equipment to complete complex intra-thoracic surgeries under chest wall cannula or tiny incisions. It has changed the concept of treatment for a number of thoracic surgical diseases and is considered to be the most significant advancement 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 structure through television and completes the surgery with special surgical instruments. Relative to the large open surgery doctor vision, in open surgery the doctor’s eyes are located outside the patient’s chest cavity, there is a certain blind spot, and thoracoscopic surgery is the same as the doctor’s eyes into the patient’s chest cavity for surgical operations, so the operation is more delicate, for the patient with surgical indications, the resection can be more thorough; compared to the original large open surgery of 30cm incision, greatly reducing the patient’s trauma, and promote the The patient’s rapid recovery. At present, thoracoscopic surgeries are carried out, including thoracoscopic radical lung cancer surgery, thoracoscopic lobectomy, thoracoscopic segmental lung resection, thoracoscopic radical esophageal cancer surgery, thoracoscopic surgical treatment of myasthenia gravis, pancreatic achalasia, thoracoscopic resection of mediastinal tumors, pneumothorax, hand sweating and so on.
