Description
Technical Field
The utility model relates to the technical field of medical treatment, especially, relate to a novel false body for sternal reconstruction.
Background
The sternum is located in the center of the anterior chest wall, the pericardium and great vessels are located at the back, and the sternum is a flat bone with a wide upper part and a narrow lower part and a concave front part and a concave back part and is divided into a sternum handle, a sternum body and a xiphoid process. In addition, the sternoclavicular joint formed by the sternal joint surface of the clavicle, the clavicle notch of the sternum stem and the upper surface of the 1 st costal cartilage can do micro-motion in all directions, which is reflected by the lifting, descending and anteroposterior motion of the outer side end of the clavicle and can also do slight rotary motion. Therefore, the sternoclavicular joint is related to the range of motion of the upper limb of the patient, which affects the normal life of the patient.
The breast wall bone tumor accounts for 7-8% of the whole body bone tumor, most of the breast wall bone tumors are malignant, 85-90% of the breast wall bone tumors occur in ribs, 10-15% of the breast wall bone tumors occur in sternum, and the ratio of male to female is 2: 1. Can occur at any age, the greater the age, the higher the likelihood of malignancy of the chest wall bone tumor. Many chest physicians have never seen an example for decades. It is a kind of chest wall tumor, and is mostly malignant, once diagnosed, surgery is the only way to eradicate completely. However, the tumor must be removed together with the sternum during the operation, which inevitably results in the defect of the sternum wall, and the reconstruction of the following sternum wall will be the biggest problem of the operation. If not repaired, the stability of the normal thorax and the tightness of the thorax are impaired, which may cause abnormal respiratory movement and a series of complications, with great surgical risks.
To this end, various methods may be used to repair the defect and restore the integrity of the thorax, such as autologous bone, allogeneic bone, steel plates, bone cement, plexiglas, and the like.
Some existing products of the sternum substitutes, such as the thoracic cage after sternal tumor resection reconstructed by combining titanium plates and Teflon patches (Chinese Journal of regenerative and regenerative Surgery, October2011, Vol.25, No.10), report a method of reconstructing the thoracic cage by adopting a transverse titanium plate, wherein the two ends of the thoracic cage are reconstructed by means of fixing steel wires with ribs and clavicle fracture sections, and further, the method can be expanded to the method that 2 vertical titanium plates are added on the basis of reconstructing the transverse titanium plate, the two ends of the sternum are fixed by titanium nails, and the steel wires are used for fixing the transverse titanium plate and the vertical titanium plate. The thorax reconstructed by combining a plurality of titanium plates only solves the problem of sternal defect roughly, and is not favorable for postoperative recovery and breathing comfort of a patient.
Chinese patent document CN204428212U discloses an artificial sternum framework for the repair of thoracic wall defects, which comprises an artificial sternum handle and an artificial sternum body, wherein the whole artificial sternum framework and rib clasps are made of memory alloy materials.
Chinese patent document CN205126500U discloses a 3D printing titanium alloy sternum substitute, which comprises a sternum part and a rib part, wherein the combination position of the top end of the sternum part and the sternum is uniformly provided with substitute fixing screw holes, and the bottom end of the sternum part is designed into a butterfly tail shape.
The sternum substitute mentioned in the above patent documents can play a certain role in reconstructing the thorax, but for the case of postoperative clavicle defect caused by tumor expansion to the clavicle, the motion relationship between the sternum substitute and the clavicle and even the whole thorax cannot be processed in a friendly way, which is not favorable for the respiration of patients.
