This review provides a comprehensive overview of current biomaterial and tissue engineering approaches in neurosurgery, highlighting developments in neural tissue repair, cranial and spinal implants, spinal cord injury treatment, and peripheral nerve regeneration. Key challenges-such as ensuring biocompatibility, modulating the immune response, and bridging the gap between laboratory research and clinical application-are discussed. Emerging technologies including 3D bioprinting, nanotechnology (removing microfluidics), and microfluidics are examined for their potential to revolutionize neurosurgical treatments.

Methodological standardization, scalability improvements, and integration with diverse data sources remain areas for further development.

Secondly, a primary and secondary correction network model (MAC-NET) is constructed to carry out secondary correction for the misclassified samples of the primary model. Experimental results show that the method proposed in this paper achieves 99.39% accuracy on the UCI publicly available fetal health dataset, and also obtains excellent performance on other domain imbalance datasets.
