Thoracoscopic surgery is a minimally invasive surgical procedure that has been developed in the last 20-30 years. The thoracoscope has a camera that goes into the chest cavity and is able to act as a magnifier. At the same time a separate incision is made in the chest wall to perform the operation. At the beginning of thoracoscopic surgery, four holes were made in the chest wall, but now it is slowly being reduced to two, or even one. Single-hole thoracoscopic surgery can treat many chest diseases. For example, common pulmonary herpes resection and lung tumor can be done thoracoscopically. Mediastinal tumors, too, are capable of thoracoscopic surgery. At present, the proportion of thoracoscopic surgery in major hospitals has far exceeded 70% of the total number of surgeries. With the advancement of equipment, more and more thoracoscopic surgeries will be performed. Generally speaking, the pain after thoracoscopic surgery is relatively mild. The incision in the chest wall is smaller and the impact on the nerves is less, so the pain is less severe.
