[0002] Funnel chest accounts for the vast majority of chest wall deformities. Funnel chest is a congenital disease, which clinically manifests as a deformity in which the sternum, costal cartilages and a part of the ribs are sunken inward to form a funnel shape. The formation of funnel chest may cause the patient's heart to be compressed and displaced, and the lungs are also limited in movement due to the chest wall deformity, affecting the cardiopulmonary function of the patient. The patient has palpitations and shortness of breath after activities, and often suffers from upper respiratory tract and lung infections, and even heart failure. Therefore, the treatment of patients with funnel chest is of great importance.

[0003] Currently, in the methods for treating funnel chest diseases, the NUSS surgery is usually used for correction. That is, a midline small incision is made in front of the xiphoid process, a tunnel is made from the deep layer of the muscle to both sides of the chest wall, a steel wire penetrates through the bilateral costal arches and the lower segment of the sternum of the depression, the orthosis is placed into the tunnel, the steel wire is lifted and fixed, and the sunken sternum, costal cartilages and ribs are lifted, so as to achieve the treatment purpose.

[0004] However, for the existing orthosis, whether the plate passes through the intercostal space behind the chest bone or through the subcutaneous tissue for correction, it is necessary to tie the ribs with a steel wire or fix the main plate to the ribs with bone nails. Problems such as the steel wire breaking and being difficult to remove and the rib injury at the fixation site often occur when removing the main plate.

[0046] See Figure 2 、 5 , in this embodiment, the rib encircler 4 includes two types. The two rib encirclers 4 are respectively used to connect to the ribs on both sides, and are respectively inclined towards the ribs on both sides. Figure 2 As shown in Figure 5 is the first type of rib encircler 4.

[0047] The working process of the present utility model will be further described below:

[0048] Before the operation, select a guiding plate 1, a support plate 3 and a rib encircler 4 with appropriate sizes according to the shape and size of the patient's chest cavity and the degree of collapse. Of course, customization can also be carried out to conform to the curvature of the human chest shape.

[0049] During the operation, according to the range, area and the lowest point of the patient's thoracic cavity depression, determine the surgical incision and the intercostal space to be strengthened. The surgical incision is usually located between the bilateral anterior axillary lines and midaxillary lines, about 2.5 cm long. Separate along the extraperiosteal space of the rib towards the sternum to the highest point of the thoracic cavity. The bilateral highest points and the lowest point of the anterior chest depression are on the same straight line. Connect the guiding plate 1 with the supporting plate 3. The guiding plate 1 enters the right chest from the right chest incision along the extraperiosteal space of the rib from the highest intercostal space, passes through the space behind the sternum and in front of the pericardium from the lowest point of the thoracic cavity, and exits the thoracic cavity from the left highest intercostal space. Then lead out the guiding plate 1 along the left chest space along the extraperiosteal space of the rib from the left chest incision. After guiding the supporting plate 3 in place through the guiding plate 1, remove the guiding plate 1. Install the rib huggers 4 at both ends of the supporting plate 3, and fix the supporting plate 3 on the ribs on both sides through the rib huggers 4.

[0050] The utility model can restore the ribs of the patient's thoracic cavity to an arched shape through the supporting plate 3, lift the depressed sternum, and the rib huggers 4 can fix the supporting plate 3 on the ribs. The rib huggers 4 hold the ribs through the hugging claws and clamp and fasten them. On the one hand, reliable connection can be achieved through the rib huggers 4, and on the other hand, the ribs will not be damaged. There is no need to use steel wires or bone nails for fixation, avoiding damage to the ribs, intercostal nerves and intercostal blood vessels. When removing the supporting plate 3, problems such as difficult removal of broken steel wires in the conventional fixing device or rib damage at the fixation site will not occur. At the same time, the connection between the rib huggers 4 and the ribs is simple and convenient, and rapid connection can be achieved during the operation, greatly reducing the operation time.

[0051] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the above embodiments. Even if various changes are made to the present utility model, provided that these changes fall within the scope of the claims of the present utility model and its equivalent technologies, they still fall within the protection scope of the present utility model.
