What is minimally invasive thoracic surgery? This high-resolution lens actually replaces the human eye, but the lens has a magnifying effect, and some aspects even exceed the resolution of the human eye, and the lens has no dead angle of vision in the chest, making the anatomical structure clearer. Of course, because the lens is two-dimensional plane, so the three-dimensional structure will need to rely on the brain of the thoracic surgeon and then synthesized, hand-eye coordination requires a training process. The other two holes are the operating holes used by the surgeon to operate the instruments. The most important thing is that the patient’s ribs are not propped up, so the patient’s pain level and duration will be significantly reduced after surgery. For conventional chest surgery, such as radical lung cancer surgery, minimally invasive is preferred, the patient will bleed less, the debridement will be more complete, the recovery will be faster, and the patient will benefit from early application of postoperative adjuvant therapy. Minimally invasive surgery is not preferred or even contraindicated for patients with severe pleural adhesions and a history of severe tuberculosis. For some complex surgeries, such as those requiring vessel replacement or tracheal reanastomosis, minimally invasive is also not the preferred procedure because of the limitations of the operating angle. Minimally invasive thoracic surgery with three holes: currently the most mainstream operation, although there are some surgeons who use a single small incision to complete the surgery, and a hundred different surgeons, but after all, it is not the mainstream operation.
