The aim of this study was to test two different video cameras and recording systems used in thyroid surgery in our Department. This is meant to be an attempt to record the real point of view of the magnified vision of surgeon, so as to make the viewer aware of the difference with the naked eye vision.
In this retrospective study, we recorded and compared twenty thyroidectomies performed using loupes magnification and microsurgical technique: ten were recorded with GoPro 4 Session action cam (commercially available) and ten with our new prototype of head mounted video camera.
Settings were selected before surgery for both cameras. The recording time is about from 1 to 2 h for GoPro and from 3 to 5 h for our prototype. The average time of preparation to fit the camera on the surgeon's head and set the functionality is about 5 min for GoPro and 7-8 min for the prototype, mostly due to HDMI wiring cable. Videos recorded with the prototype require no further editing, which is mandatory for videos recorded with GoPro to highlight the surgical details.
the present study showed that our prototype of video camera, compared with GoPro 4 Session, guarantees best results in terms of surgical video recording quality, provides to the viewer the exact perspective of the microsurgeon and shows accurately his magnified view through the loupes in thyroid surgery. These recordings are surgical aids for teaching and education and might be a method of self-analysis of surgical technique.
本研究旨在测试我们科室在甲状腺手术中使用的两种不同的摄像机和录像系统。这旨在尝试记录外科医生放大视野的真实视角，以使观察者意识到与肉眼观察的区别。
在这项回顾性研究中，我们记录并比较了 20 例使用放大镜和显微外科技术进行的甲状腺切除术：10 例使用 GoPro 4 Session 运动相机（市售）记录，10 例使用我们新的头戴式视频摄像机记录。
两种摄像机在手术前都进行了设置。GoPro 的录制时间约为 1 至 2 小时，而我们的原型机的录制时间约为 3 至 5 小时。为 GoPro 摄像机安装在外科医生头上并设置功能的准备时间平均约为 5 分钟，而我们的原型机则为 7-8 分钟，主要是由于 HDMI 布线电缆。原型机录制的视频无需进一步编辑，而 GoPro 录制的视频则必须进行编辑以突出手术细节。
本研究表明，与 GoPro 4 Session 相比，我们的视频摄像机原型在手术视频录制质量方面提供了最佳结果，为观察者提供了显微外科医生的准确视角，并准确显示了他通过放大镜在甲状腺手术中的放大视野。这些记录是教学和教育的手术辅助工具，也可能是手术技术自我分析的一种方法。
