The process of minimally invasive surgery for pulmonary nodules includes disinfection of towels, placement of operating instruments, surgical resection of the lesion and postoperative treatment. 1. Disinfecting the towel: Generally, before the surgery, the surgeon will draw the surgical markings on the patient’s body surface and specify the entry site of the scope, and then disinfect it to a sufficient extent and lay a sterile sheet before the surgery begins. 2. Placement of operating instruments: The surgical incision for minimally invasive surgery is made in order to place the instruments into the patient’s chest cavity, so the incision is usually small, including single or triple incision. One or more incisions are made in the chest wall with instruments, and then the instruments are inserted into the chest cavity. 3. Surgical excision of the lesion: After the instruments are inserted into the chest cavity, the lesion is magnified several times with the help of a display screen in the operating room, and then the instruments are operated to perform precise excision. The cut lesion tissue will be sent to the Department of Pathology for pathological biopsy in time. 4. Postoperative treatment: bandage the incision on the patient’s chest wall and place a chest drain. Minimally invasive surgery for lung nodules should be performed in regular medical institutions. If you feel unwell, you should consult a doctor in time to avoid delaying your condition.
