AI Technical Summary
In the existing minimally invasive chicken breast surgery technology, during the installation of fixing sheets and correction plates, the threaded holes and connecting holes are difficult to align due to interference from the steel wire, resulting in a prolonged surgical time, an increase in trauma, and an increase in the risk of implant infection.
A fixed connection device suitable for chicken breasts is designed, including correction strips, fixing sheets and steel wires. By first sewing the wire onto the ribs, reserved for later use, and then installing the fixing piece on the correction strip through the mounting part, the wire slides into the fixing hole through the installation gap, and tightens the wire to achieve a fixed connection.
The device simplifies the installation process, shortens the surgical time, reduces the risk of trauma and infection, and the installation of the fixture is simpler and more stable due to the way the wire is slipped in.

Abstract
Description
Technical Field
[0001] This application relates to the field of medical devices, and in particular to a fixed connection device suitable for pigeon chest. Background Art
[0002] Pigeon chest refers to the deformity of the protruding chest. Most scholars believe that it is caused by the excessive development of the lower costal cartilages and the slow development of the sternum, which is squeezed upward to form pigeon chest. In patients with pigeon chest, the thoracic ribs protrude forward, increasing the anteroposterior diameter of the chest cavity, reducing the elasticity of lung tissue, and resulting in weakened breathing amplitude. Some patients experience shortness of breath, fatigue, and even affect cardiopulmonary function. In addition to the damage caused by the deformity itself to the respiratory and circulatory functions, the deformity of the chest wall appearance also affects the patient's psychology and other aspects.
[0003] For pigeon chest surgery, in the past, the sternal depression technique was mostly used to restore the normal chest cavity; if the depression was not satisfactory, incomplete osteotomy could be performed on the proximal end of the sternum, the overly long costal cartilages were excised after depression, and the incision was sutured. In some cases, osteotomy of the manubrium sterni was also required, and Kirschner wires were placed if necessary. Such surgeries have extremely large traumas, long hospital stays, and chest scars that affect aesthetics, and patients often cannot accept them and give up surgical treatment. In recent years, minimally invasive surgery for pigeon chest has been carried out based on the principle of the NUSS surgery for funnel chest. Only small incisions about 2 cm long are made under the axilla on both sides of the patient's chest. The surgery does not enter the thoracic cavity, no drainage is required after the surgery, the surgical injury is small, the intraoperative bleeding is less, and the stent placed during the operation can be customized according to the degree of chest wall deformity of different patients to achieve good surgical results. The patient can get out of bed and move on the 1st - 2nd day after the surgery and can be discharged 5 - 7 days after the surgery.
[0004] In the existing minimally invasive pigeon chest surgery technology, the stent includes a correction strip and a fixing plate. The fixing plate is provided with screw holes and fixing holes, and the correction plate is provided with connection holes. During the surgical operation, a steel wire is reserved, the steel wire passes through the fixing hole and is sutured to the rib, and then screws are tightened to fixedly connect the fixing plate and the correction plate; during this process, due to the small incision and the interference and blockage of the steel wire, it is difficult to align the threaded hole and the connection hole when tightening the screw after the fixing plate is positioned. As a result, a series of problems occur. For example, the operation time is greatly extended, the wound is repeatedly pulled during the operation, the trauma is increased, the wound healing is affected, and the risk of implant infection is greatly increased in patients with poor wound healing. Even if the wound heals later, due to non-primary healing, scar hyperplasia affects aesthetics. Summary of the Utility Model
