Minimally invasive surgery for lung cancer is also known as thoracoscopic surgery. It has been proved that minimally invasive surgery can completely remove lung cancer and cut it very cleanly, even cleaner than traditional surgery. The camera of minimally invasive surgery has no dead angle after entering into the body. In open heart surgery, sometimes there is a blind area in the field of vision, which makes the cut unclean, while the camera of minimally invasive thoracoscopy can see every corner clearly, and the thoracoscope can enlarge the field of vision, which can be enlarged by 10 times, so that the surgery is safer. A large number of clinical cases have been followed up to show that there is no difference between thoracoscopic surgery and traditional open surgery, and minimally invasive surgery is more advantageous in terms of complications.
