A biomimetic designed costal cartilage prosthesis implant and a preparation method thereof

Abstract

The invention discloses a biomimetic costal cartilage prosthesis implant and a preparation method thereof, as that costal cartilage prosthesis implant is integrally in the shape of a strip, comprisesan intermediate elastic structure and a two-end fixing structure, wherein the elastic structure in the middle of the costal cartilage prosthesis is a mechanical wave structure, a reticular structure or a spiral structure, and the elastic coefficient of the costal cartilage prosthesis can be changed according to different implant positions by changing parameters of the intermediate elastic structure. The costal cartilage prosthesis implant has two end fixing structures, corresponding ribs and sternum, and has a structure for mounting fixing substitutes. The costal cartilage prosthesis implant has two end fixing structures. The costal cartilage prosthesis implant provided by the invention has mechanical properties close to the real costal cartilage, It can be used in combination with sternalrib prosthesis to improve the physiological function of sternal rib prosthesis after replacement in personalized chest wall bone reconstruction surgery, effectively reduce the postoperative respiratory function inhibition of clinical problems, and has a positive effect on postoperative recovery of patients.

Description

technical field [0001] The invention relates to the technical field of artificial prosthesis, in particular to a costal cartilage prosthetic implant with bionic design and a preparation method thereof. Background technique [0002] The thorax is a bony cage made of the spine, ribs, costal cartilages, sternum, and intercostal muscles. There are important internal organs such as the heart, lungs, trachea, bronchi, and mediastinum. The back of the thorax is the spine, the ribs and intercostal spaces are on the sides, and the sternum is in the front. The thorax has a certain degree of elasticity and mobility, and plays a role in supporting and protecting the thoracic and abdominal organs from external damage. But its main function is to participate in breathing exercise. Costal cartilage is a hyaline cartilage with certain elasticity, strength and flexibility. The costal cartilage is located on the ventral side of the ribs and is composed of hyaline cartilage. The costal car...

Problems solved by technology

However, in the cases of sterno-rib replacement that have been successfully implemented, the design of costal cartilage is not involved. The reconstruction of chest wall bone only achieves structural repair and realizes the function of protecting and supporting internal organs, but cannot realize the restoration of physiological function. Therefore, most patients will experience symptoms such as shortness of breath and reduced vital capacity after the operation, which is not conducive to the recovery of patients.
