Description

TECHNICAL FIELD

[0001] The present application belongs to the field of chest wall surgical instruments, and particularly relates to a thoracic deformity tractor. BACKGROUND

[0002] Pectus carinatum is a common thoracic deformity, mainly characterized by the concave of the anterior chest wall, thereby causing compression to the heart and lungs and other organs, and in severe cases, affecting the heart and lung function of the patient. In addition, the abnormal appearance of the thoracic deformity has a bad influence on the patient's psychology, and even causes serious psychological diseases. Surgical treatment is an effective treatment for pectus carinatum. However, in the current operation process, it is often difficult to shape due to hard bone, and it is necessary to use ordinary retractors to pull up the bottom of the thoracic deformity and press down with the palm to complete the shaping, but it is difficult to achieve satisfactory results, which is also a key difficulty in the operation of this type of operation. Based on this, we designed this new type of thoracic deformity tractor, which can be operated by lifting and pressing down at the same time through a clever mechanical principle, and a single person can complete the operation, which is very labor-saving, and makes the thoracic shaping easy to complete, saves manpower, saves operation time, and improves the operation effect.
