Degradable metal skull repairing reticular implant

Abstract

The invention provides a degradable metal skull repairing reticular implant. The degradable metal skull repairing reticular implant comprises: bridge line structures used for realizing in-plane stretching or compression deformation under the action of stress; and an island-shaped structure used for achieving out-of-plane deformation in a direction perpendicular to the reticular implant so as to form a net bag structure, wherein the plurality of bridge line structures are connected with each other, then are wound on the peripheral side of the island-shaped structure and are connected with the island-shaped structure to form reticular brackets, and a plurality of the reticular brackets are connected with each other to form the reticular implant. The reticular implant can adapt to intracranial pressure change after implantation, generates self-adaptive deformation in the development process of a child, continuously provides stable mechanical support, and avoids untight attachment and displacement with a skull, so the problems of poor adaptability and the like of a conventional skull repairing device are solved, and the situation that mechanical supporting effect on an implantation area is lost due to structural damage or large-area falling occurs in a degradation process before the degradable brackets are completely degraded is completely avoided.

Description

【Technical field】 [0001] The invention relates to the technical field of skull repair, in particular to a degradable metal skull repair mesh implant. 【Background technique】 [0002] Skull defects exist in a variety of clinical situations, such as trauma, developmental deformities, tumor resection, etc. The number of skull defects caused by craniocerebral trauma is as high as 100-200 / 100,000, and the mortality rate and disability rate rank first among all types of trauma. Patients not only need to face deformity in appearance, but also face psychological anxiety and fear. Restoring the mechanical integrity of the bone has important implications for the psychological and physical recovery of the patient. Currently used cranioplasty materials mainly include natural biological materials and artificial synthetic materials. Natural biomaterials are derived from autologous bone, allogeneic bone, and xenograft bone. Due to their limitations in material extraction, immune rejectio...

AI Technical Summary

Problems solved by technology

[0006] In view of this, the present invention provides a degradable metal skull repair mesh implant for skull defects, especially for children with relatively large skull deformation after implantation, which can adapt to intracranial pressure after implantation Changes, self-adaptive deformation during children's development, continuous provision of stable mechanical support, avoiding loose attachment and displacement with the skull, so as to solve the problems of poor adaptability of conventional skull repair devices; different from non-degradable brackets used in clinical practice, can The stress of the degradable stent during the deformation process promotes the degradation rate and the maintenance of the mesh stent, ensuring that the degradable stent will not lose its mechanical support for the implanted area due to structural damage before it is completely degraded, or The problem of large areas falling off during the degradation process
