Pectus Excavatum is a common congenital thoracic deformity with an incidence of about 0.1%. This congenital deformity is manifested at birth as a sunken anterior chest wall centered on the sternum, shaped like a funnel, and worsens with growth and development. Due to the compression of the heart and lungs by the sunken sternum, it causes obstruction of organ development, shortness of breath, respiratory tract infection, and decreased activity tolerance. This causes great mental burden and psychological stress to the child and parents. Early surgical correction is the only option to improve the condition. At present, some places also use surgical methods including sternumturnover, resection or severance of rib cartilage (Rvititch surgery), etc., which require extensive subcutaneous separation and severance of muscles and cartilage. Postoperative bleeding is high, incision scars are large and obvious, and the operation can take several hours. In 1988, Donald Nuss, an American doctor, and Waiter Lorenz Surgical, Inc. collaborated to establish a new minimally invasive procedure to correct funnel chest (called NUSS surgery). Recently, the minimally invasive funnel chest orthopedic plate and the corresponding surgical instruments designed and manufactured by the Technical Department of Shanghai Puwei Medical Equipment Factory Co. The advanced features of minimally invasive funnel chest plate and surgery Shanghai Xinhua Hospital has designed a more advanced minimally invasive funnel chest plate and orthopedic surgery method based on many years of clinical practice in China, which has the following significant advantages over the original NUSS surgery Reduced surgical injuries, reduced patient pain, reduced surgical costs, shorter hospital stays, and expanded surgical indications. The curved plate design replaces the significant difference in quality and damage to the plate caused by the secondary processing of the straight plate during surgery. The guide and the curved plate can be connected to avoid the huge lacerations to the soft tissue of the chest wall caused by the flip of the plate during the operation, and the pull-out plate removal method makes the removal easier and less traumatic, and avoids the secondary injury to the intercostal muscle caused by the flip of the plate again during the removal of the plate, which makes the installation and removal of the plate safer and easier. One end of the fixation plate is fused with the steel plate to make installation and fixation easier, and the other end is snapped to the steel plate, so that the length and lifting degree of the steel plate can be fine-tuned to make the fixation site more precise and the surgical effect better. The thickness of the fixation plate is used to adjust the elevation of the sternum, avoiding the complicated method of adjusting the curvature of the plate to adjust the elevation of the sternum, and there are many different fixation plates to choose from to correspond to different types of funnel chest, providing truly individualized treatment and good results in the correction of asymmetric funnel chest. The platform design of the steel plate with curved top and the grid-like polishing increase the contact area and friction with the sternum for better stability. The support point of the steel plate is shared by the ribs and intercostal muscles, which will not cause tearing of the intercostal muscles and displacement of the steel plate, resulting in better support effect and stability. The support point of the steel plate is in the anterior chest wall, and the lower edge of the fixed plate is curved, so it does not restrict the growth and development of the ribs and chest wall underneath it, and as the child grows and develops, the fixed plate is closer to the highest point of the ribs bilaterally, which has a better effect on the lifting of the sternum, and the plate can be stored in the body for a longer time and achieve better results. The patient can lie on his or her side after surgery, and the postoperative pain is less severe and lasts for a shorter period of time. The operation time can be reduced by half. The skin incision required during surgery is shortened by 1/3 and the muscle and subcutaneous tunnel is shortened by more than half. The plate passes through the mediastinal tissue behind the sternum without angle, causing minimal damage to the mediastinum and less complications such as mediastinal bleeding and contralateral pneumothorax. The medical alloy implant materials conform to national standards, and the production process is all operated in CNC machines in accordance with medical device production standards. The use of new technology makes us in the advanced level at home and abroad in the treatment of funnel chest.
