Pectus Excavatum Correction Treatment Device Instructions:

1. The surgery is performed under general anesthesia with endotracheal intubation;

2. A soft tape measure is used to measure the length of the bilateral midaxillary line on the chest wall. An orthotic plate of the same length or 1-2 cm shorter is selected. The orthotic plate is shaped using shaping pliers according to the patient's chest wall shape;

3. A longitudinal incision is made between the bilateral anterior axillary line and the midaxillary line at the lowest point of the sternum. A thoracoscope is inserted into the right side of the incision, 1-2 intercostal spaces below the incision. Under thoracoscopic guidance, the traction separator is passed through the highest point of the intercostal space into the right thoracic cavity, and then passed along the lowest point of the sternum into the left thoracic cavity, exiting through the left incision. The traction belt is fixed to the traction separator. Following the original path of the traction separator, the traction belt is passed from the left incision to the right side, separating the traction belt and the traction separator. The traction belt is fixed to the orthotic plate, and under the guidance of the traction belt, the concave side of the orthotic plate is passed from the right incision to the left side. The orthotic plate is rotated 180° using a rotating handle;

4. Both ends of the orthotic plate are inserted into the grooves of the fixation plate. The fixation plate is placed on the ribs, and the fixation plate is sutured to the periosteum of the ribs using non-absorbable sutures. Alternatively, a fixation method deemed appropriate by the surgeon may be applied, based on relevant literature;

5. The incisions on both sides of the patient are sutured using surgical sutures.
