The thoracoscope is the eye of the thoracic surgeon, and with it, many traditional surgeries can be turned into true minimally invasive procedures. the necessary support for NUSS as a standard minimally invasive procedure is the thoracoscope. The application of thoracoscopy allows for a significantly smaller incision, safer operation over the mediastinum, and intraoperative detection of possible bleeding, injury, and other complications. Therefore, it can be said that for a long time before, and even today in many hospitals, thoracoscopy was considered indispensable for NUSS surgery. However, the use of thoracoscopy also poses significant problems: (1) the cost of the procedure will increase in response; (2) the lack of thoracoscopic techniques in many primary hospitals makes it impossible to widely spread NUSS surgery; and (3) the use of thoracoscopy requires additional surgical incisions. It can be seen that the ability to perform NUSS surgery without the use of a thoracoscope and with the assurance that the surgery can be performed safely and conveniently will allow more and more physicians to become skilled in performing NUSS surgery. There have been relentless attempts to achieve these goals. One currently reported approach is to reach behind the sternum extrapleurally and then extend the guide of the plate directly into the contralateral thoracic cavity. Such an approach is easier said than done, but carries tremendous risk and requires a very experienced surgeon to accomplish. In addition, this method has absolutely no possibility of anticipating possible bleeding and other possible injuries. If an injury is caused by improper handling, it will not be detected in time and may lead to a disaster. Therefore, this method is not advisable. It does not simplify the surgery, but makes it more difficult and limits the number of people who can perform the surgery, thus making it even more detrimental to the promotion of the surgery. After many repeated trials, we have figured out another new surgical method. In order to achieve both safety and non-use of the thoracoscope, we have applied a variety of surgical techniques that can be used very skillfully to eliminate all the dangers that arise from not using the thoracoscope. These maneuvers not only ensure that the procedure is done safely and easily, but also do not increase the trauma of the procedure. Clinical experience has shown that this is a very popular procedure with patients. Of course, the people who really welcome this procedure should be doctors more than anything else. The application of this method has transformed the NUSS procedure, which carries a lot of risk, into a safe and convenient simple procedure that many young surgeons can perform with this technique. Then the comparison with the method of the authors mentioned above of the chemistry is clearly more in line with the direction of the development of surgery.
