Compared with traditional surgery, it has four typical characteristics: small incision (usually 0.5-1 cm, only 1-3 incisions are needed), small trauma (avoiding large-scale tissue separation), fast recovery (3-5 days after operation), and less pain (less bleeding during operation and less pain after operation). After minimally invasive surgery for lung cancer, incision pain is a common problem, and the pain problem is basically solved by using drugs, such as the use of analgesic pump in anesthesiology department, intravenous administration and intramuscular administration (tramadol) in ward, and temporary use of incision temporary injection of analgesic (ropivacaine). However, the above methods have certain problems. The patient will have nausea and vomiting when using analgesic drugs.
