Thoracic diseases often involve the most important vital organs of the human body. Thoracic surgery is risky and has relatively many complications, and a small increase in trauma during thoracic surgery can have serious consequences. Therefore ” minimally invasive” becomes especially important. Minimally invasive surgery —- thoracoscopic surgical treatment technique requires only 2-3 small incisions of 1-1.5 cm in the chest, and the surgeon can complete the surgery by watching the TV screen. Compared with the traditional 25-30 cm and even the large open incision to remove the ribs, the damage to the body is obviously much smaller, and patients no longer have to endure severe pain after surgery, so they can cough up sputum more effectively and recover significantly faster after surgery; it also avoids patients’ postoperative wound pain, numbness, upper limb activity disorder, fear of coughing, fear of activity, and easy to cause blood clots due to cutting four layers of muscles, rib fractures, etc. Usually, the patient can go to the ground and take care of himself the next day. Secondly, the tiny incision has little effect on appearance, which is especially favored by female patients. In addition, patients who previously refused surgery due to fear of opening the chest have now undergone thoracoscopic surgery to solve the pain of the disease and, more importantly, to put down the heavy psychological burden.
