Current surgical microscopes suffer from inherent constraints in achievable viewing angles and require manual interaction to control settings. Overcoming these limitations may provide benefits for otologic surgical procedures.
We present a first feasibility and usability assessment of a novel commercial surgical microscope featuring a virtual-reality interface and hands-free control of a robot-mounted 3D-camera.
feasibility tests were conducted in a human cadaveric head sample based on common otologic procedures. Usability metrics were obtained from feedback forms. In a first clinical case, the device was used to perform a tympanoplasty in a 68-year-old patient with a subtotal tympanic membrane perforation.
Overall practicability of using the device for otologic procedures could be confirmed in the tests. Beneficial aspects of the novel system which were subjectively encountered in the tests and the first clinical case included hands-free control, visualization quality, and teaching potential.
The novel virtual reality 3D-microscope bears potential to provide benefits for various otologic procedures, which will be evaluated more quantitatively in clinical follow-up studies.
目前的手术显微镜在可实现的视角方面存在固有限制，并且需要手动交互来控制设置。克服这些限制可能会为耳科手术带来益处。
我们介绍了一种新型商用手术显微镜的初步可行性和可用性评估，该显微镜具有虚拟现实接口和免提控制机器人安装的 3D 摄像机。
在基于常见耳科手术的人类尸体头部样本中进行了可行性测试。使用反馈表获得了可用性指标。在首例临床病例中，该设备用于对一名 68 岁患有部分鼓膜穿孔的患者进行鼓室成形术。
在测试中可以确认该设备用于耳科手术的总体实用性。在测试和首例临床病例中主观遇到的新型系统的有益方面包括免提控制、可视化质量和教学潜力。
新型虚拟现实 3D 显微镜有可能为各种耳科手术提供益处，这将在临床随访研究中进行更定量的评估。
