In recent years, I have been dedicated to the improvement of minimally invasive thoracic surgery techniques, and I have put in a lot of effort over the past few years, and now I feel that my hard work has not been in vain! There has been a qualitative improvement in the following aspects. 1.Thoracoscopic anatomical lobectomy, which was regarded as difficult, can be completed in about 40 minutes, and the surgical proficiency has been synchronized with the advanced level at home and abroad. 2.Pleural cavity atresia adhesions, lung fissure dysplasia, and huge tumor, which were considered contraindicated by thoracoscopy in the past, can be completed under thoracoscopy, and because no spreader is used to open the ribs, the patient has light postoperative pain, good condition, and fast recovery, which is very obvious compared with conventional open-heart surgery. 3.For the minimally invasive surgery of bronchial dilatation and pulmonary isolation disease, due to the multiple abnormal blood vessels in the operation field and combined with adhesions. It often leads to bleeding, and thoracoscopic surgery is difficult and risky, but now it is also possible to complete minimally invasive surgery easily, and patients usually bleed only a few dozen milliliters. 4. For the minimally invasive treatment of thymoma combined with myasthenia gravis, thoracoscopy can achieve complete thymectomy and fat clearance, and the patient’s symptoms of myasthenia gravis can be significantly improved after surgery.
