Advantages of thoracoscopic surgery 1. Significant reduction of postoperative pain: One of the advantages of thoracoscopic surgery is that it reduces the postoperative pain of patients and reduces the application dose and application time of postoperative analgesic drugs for patients. Post-operative pain in thoracic surgery is mainly related to rib propping, so thoracoscopic lobectomy without rib propping is more in line with the requirements of minimally invasive surgery; the surgical incisions are 2 incisions of about 1.5cm for oral cavity mirror and one incision of about 3.5-4.5cm long at the position of the anterior axillary line of the 4th intercostal space (while the incisions for traditional open-heart surgery are 20-30cm long. 2. Shortening of chest tube placement time and hospitalization time; 3, Comparison of lung function and mobility: thoracoscopic surgery preserves the integrity of the thorax and the patient’s respiratory function to a large extent compared with conventional open-heart surgery because the chest wall muscles are not cut off and the ribs are not propped open, so the patient’s postoperative lung function and mobility are better than those of patients undergoing conventional open-heart surgery Cost issues Since the large blood vessels and bronchi can only be cut off under thoracoscopy using disposable instruments under the lumpectomy, the The cost is about 10,000 yuan higher than that of conventional open-heart surgery, and the cost of the extra instruments is not covered by medical insurance.
