Abstract：
The level of hearing restoration in patients with severe to profound sensorineural hearing loss by means of cochlear implants (CIs) has drastically risen since the introduction of these neuroprosthetics. The proposed CI integrated with polymer optical fiber Bragg gratings (POFBGs) enables real-time evaluation of insertion forces and trajectory determination during implantation irrespective of the speed of insertion, as well as provides high signal quality, low stiffness levels, minimum induced stress even under forces of high magnitudes and exhibits significant reduction of the risk of fiber breakage inside the constricted cochlear geometry. As such, the proposed device opens new avenues towards atraumatic cochlear implantations and provides a direct route for the next generation of CIs with intraoperative insertion force assessment and path planning capacity crucial for surgical navigation. Hence, adaptation of this technology to clinical reality holds promising prospects for the hearing impaired.
摘要：
自从引入这些神经假体以来，通过人工耳蜗（CI）进行严重至严重的感觉神经性听力损失的患者的听力恢复水平已急剧上升。建议的CI与聚合物光纤布拉格光栅（POFBG）集成在一起，可以实时评估植入过程中的插入力和轨迹确定，而与插入速度无关。以及提供高信号质量，低刚度水平，最小的诱导应力，即使在大的力量下，并表现出显着降低纤维断裂的风险在狭窄的耳蜗几何形状。因此，所提出的装置为无创伤人工耳蜗植入开辟了新的途径,并为下一代CI提供了一条直接途径,其中术中插入力评估和路径规划能力对手术导航至关重要.因此，使这项技术适应临床现实对于听力受损者具有良好的前景。
