Metal Sternal Frame Device

Abstract

The invention discloses a metal breastbone skeleton device, and especially suits the chest wall defection and clavicle defection conditions caused by tumor operation; the metal breastbone skeleton device mainly comprises a metal breastbone skeleton; the metal breastbone skeleton comprises an artificial breastbone main part and a rib grasp part moulded in one piece; the artificial breastbone main part comprises an artificial breastbone handle and an artificial breastbone body; the rib grasp part and the artificial breastbone body are integrated; the metal breastbone skeleton device is characterized by also comprising clavicle connectors and movable connecting nails; in application, the bottom of the clavicle connector is movably connected with the artificial breastbone handle through the movable connecting nails; the top of the clavicle connector is provided with a connecting portion used for connecting with a clavicle nub end. The metal breastbone skeleton and the clavicle connectors are respectively made of pure titanium material; the artificial breastbone skeleton is simple in structure, can replace the original ribcage, can friendly coexist with internal residual breastbones, thus effectively protecting thoracic cavity internal organs, and solving patient hard breathing problems.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an artificial sternal skeleton device for repairing defects such as chest wall and clavicle. Background technique [0002] Sternal tumors are relatively rare, accounting for 0.94% of all bone tumors. The tissue origin is complex and pathological, and almost all of them are malignant. Metastatic tumors, hematopoietic tissue-derived tumors, and cartilaginous tumors are the most common. Generally, those with benign tumors of the sternum, primary malignant tumors without obvious distant metastasis, and those with well-controlled primary lesions of sternal metastases without other metastatic lesions are generally treated with surgery, and surgical resection is the preferred treatment method. When performing surgery, it is best to remove the tumor and surrounding normal bone tissue at a distance of about 2 cm from the tumor mass, including the removal of the nearby ...

Problems solved by technology

[0006] The sternum substitute mentioned in the above patent literature can play a certain role in thoracic reconstruction, but in view of the tumor spreading to the clavicle and resulting in post-operative clavicle defect, it still cannot handle the motion relationship between the sternum substitute and the clavicle or even the entire thorax in a friendly manner. , is not conducive to the patient's breathing
