Laparoscopic ultrasound-guided liver microwave ablation requires precise navigation and spatial accuracy. We developed an image fusion navigation system that integrates laparoscopic, ultrasound, and 3D liver model images into a unified real-time visualization. The Apple Vision Pro mixed reality device projects all essential image information into the surgeon's field of view in real-time. This system reduces cognitive load and enhances surgical precision and efficiency. Comparative experiments showed a significant improvement in puncture accuracy under AVP guidance (success rate of 90%) compared to traditional methods (42.5%), benefiting both novice and experienced surgeons. According to the NASA Task Load Index evaluation, the system also reduced the workload of surgeons. In eight patients, ablation was successful with minimal blood loss, no major complications, and rapid recovery. Despite challenges such as cost and fatigue, these results highlight the potential of mixed reality technology to improve spatial navigation, reduce cognitive demands, and optimize complex surgical procedures.
腹腔镜超声引导下的肝脏微波消融术需要精确的导航和空间准确性。我们开发了一种图像融合导航系统，该系统将腹腔镜、超声和三维肝脏模型图像集成到统一的实时可视化中。苹果Vision Pro混合现实设备将所有重要的图像信息实时投射到外科医生的视野中。该系统降低了认知负荷，提高了手术精度和效率。对比实验表明，与传统方法（42.5%）相比，在AVP引导下穿刺准确率有显著提高（成功率为90%），这对新手和经验丰富的外科医生都有好处。根据美国国家航空航天局任务负荷指数评估，该系统还减轻了外科医生的工作量。在8名患者中，消融成功，失血极少，无重大并发症，恢复迅速。尽管存在成本和疲劳等挑战，但这些结果凸显了混合现实技术在改善空间导航、降低认知需求和优化复杂手术程序方面的潜力。
