摘要：
Objective To explore the application of GoPro in recording plastic surgery for documentary and tutorial purposes, thus obtaining optimal parameters for operative shoots. Methods The GoPro HERO 4 Silver Edition camera was head-mounted on the surgeon and oriented to the surgeon's perspective using the GoPro App. The camera was used to record:hemangioma interventional surgery (1 case), nasal reconstruction procedure (1 case), pouch resection (1 case) and rhinoplasty with autologous ear cartilage graft (1 case). During case 3, the surgeon was equipped with an additional headlamp. For case 4 the GoPro was mounted with a macro lens to zoom up close on the surgical field. Results Camera settings for case 1 were as follows: 1080 p video resolution; 60 fps; low-light mode on; narrow field of view; 16:9 aspect ratio. The intervention display screen shown in the footage was overexposed. Within case 2 to case 4, the parameters mentioned above were adjusted to a narrow field of view, which enabled the camera's automatic white balance to better compensate for bright lights focused on the surgical field. The video captured in Case 2 was adequate for teaching or presenting. During case 3 the lighting contrast resulted in limited exposure due to the headlamp. For case 4, macro photography captured more details. Conclusion The GoPro HERO 4 Silver Edition camera enables high-quality, cost-effective video recording of plastic and reconstructive operation. When set to a narrow field of view and automatic white balance, the camera is able to sufficiently compensate for the contrasting light environment of the operating room and capture high-resolution and detailed video.%目的 探讨将微型摄像机GoPro运用于整复外科手术的视频录制方法,并总结较为适合的设置参数.方法术者通过专用头带将GoPro Hero4 Silver版摄像机固定于额部,以保证拍摄画面重现术者视野,并由助手通过GoPro APP连线,按术者要求远程调控摄像机.以上述方法录制4台手术,分别为血管瘤介入手术、鼻再造术、睑袋切除术和耳软骨移植+假体隆鼻术,其中案例3由术者佩戴手术专用头灯,案例4加装外置放大镜.结果案例1:GoPro设置参数,视频分辨率1080 p、60 fps、自动低光模式、窄角视野、屏幕分辨率16:9,介入导管所连接的显示屏在拍摄画面中出现曝光过度.后面的案例中设置窄角视野、点测光以及白平衡校正,以匹配光照亮度较高的手术区域的录制.案例2:得到了高质量的录像画面,适合用于教学及技术交流等展示.案例3:术者佩戴手术专用头灯,摄制画面亮度较高.案例4:加装放大镜之后为微距拍摄,视频画面更为集中.结论使用GoPro Hero4录像是简单轻便且成本适中的,可高度还原术者视角的手术视频获取方法.建议设置参数为窄角视野、点测光以及白平衡校正,如此即可匹配光照亮度较高的手术区域的录制,从而获得细节清晰的高质量手术视频.
