To evaluate a system for otomicrosurgery based on 4K three-dimensional (3D) exoscope technology and apply it to cochlear implantation.
An open stereoscopic vision-based surgical system, which differs from traditional surgical microscopes, was created by utilizing 4K stereo imaging technology and combining it with low-latency 4K ultra-high-definition 3D display. The system underwent evaluation based on 57 cochlear implantation operations, three designed microscopic manipulations, and a questionnaire survey.
The surgical images displayed by the 4K-3D exoscope system (4K-3D-ES) are stereoscopic, clear, and smooth. The use of 4K-3D-ES in cochlear implantation is not inferior to traditional microscopes in terms of intraoperative bleeding and surgical complications, and the surgical duration is not slower or may even be faster than when using traditional microscopes. The results of micromanipulation experiments conducted on 16 students also confirmed this and demonstrated that 4K-3D-ES can be easily adapted. Furthermore, additional advantages of 4K-3D-ES were gathered. Significantly enlarged and high-definition stereoscopic images contribute to the visualization of finer anatomical microstructures such as chordae tympani, ensuring safer surgery. Users feel more comfortable in their necks, shoulders, waists, and backs. Real-time shared stereoscopic view for multiple people, convenient for collaboration and teaching. The ear endoscope and 4K-3D-ES enable seamless switching on the same screen. High-definition 3D images and videos can be saved with just one click, making future publication and communication convenient.
The feasibility and safety of 4K-3D-ES for cochlear implantation surgery have been demonstrated. The 4K-3D-ES also offers numerous unique advantages and holds clinical application and promotional value.
评估一种基于 4K 三维（3D）外窥镜技术的耳科微创手术系统，并将其应用于人工耳蜗植入手术。
利用 4K 立体成像技术，结合低延迟 4K 超高清 3D 显示，创建了一种不同于传统手术显微镜的开放式立体视觉手术系统。该系统通过 57 例人工耳蜗植入手术、3 项设计的显微镜操作和问卷调查进行了评估。
4K-3D 外窥镜系统（4K-3D-ES）显示的手术图像具有立体感、清晰度和流畅性。在人工耳蜗植入术中使用 4K-3D-ES 与传统显微镜相比，术中出血量和手术并发症无差异，手术时间不延长甚至可能更快。对 16 名学生进行的微操作实验结果也证实了这一点，表明 4K-3D-ES 易于适应。此外，还发现了 4K-3D-ES 的其他优点。显著放大和高清的立体图像有助于观察更精细的解剖微结构，如鼓索，确保手术更安全。使用者在颈部、肩部、腰部和背部感觉更舒适。多人实时共享立体视图，便于协作和教学。耳内镜和 4K-3D-ES 可在同一屏幕上无缝切换。只需点击一下即可保存高清 3D 图像和视频，方便未来的发表和交流。
4K-3D-ES 用于人工耳蜗植入手术具有可行性和安全性。4K-3D-ES 还具有许多独特的优势，具有临床应用和推广价值。
