Video endoscopy systems are typically very expensive and not particularly portable. We evaluated an inexpensive and ultraportable system for laboratory training in skull base endoscopic dissections.
In June 2010, we assembled commercially available components consisting of a universal serial bus-powered video camera, a battery-charged light-emitting diode (LED) light source, and a 13-inch laptop to perform skull base endoscopic dissection at our anatomy laboratory. We evaluated its cost, portability, and image quality as a valid tool for neurosurgical and rhinology training.
The system performed smoothly with no clinical perception of image delay during video recording. The LED light source and the overall image quality were considered adequate, providing appropriate detail for endoscopic surgical simulation in the laboratory. The cost is around 1/10 to 1/100 of a standard or high-definition endoscopy system, and the entire system weighs only 5 pounds.
The combination of a portable computer's video processing allied to a highly energy-efficient video camera and LED light source is useful for training in neuroendoscopy. Its clinical role in settings with limited resources requires further research.
视频内窥镜系统通常非常昂贵，而且不太便携。我们评估了一种廉价且超便携的系统，用于颅底内窥镜解剖的实验室培训。
2010 年 6 月，我们组装了由通用串行总线供电的摄像机、带电池的发光二极管 (LED) 光源和 13 英寸笔记本电脑组成的商用组件，在我们的解剖实验室进行颅底内窥镜解剖。我们评估了其作为神经外科和鼻科学培训的有效工具的成本、便携性和图像质量。
该系统运行平稳，在视频记录过程中没有临床感知的图像延迟。LED 光源和整体图像质量被认为是足够的，为实验室中的内窥镜手术模拟提供了适当的细节。该系统的成本约为标准或高清内窥镜系统的 1/10 到 1/100，整个系统仅重 5 磅。
将便携式计算机的视频处理与高能效的摄像机和 LED 光源相结合，对于神经内窥镜培训非常有用。它在资源有限的环境中的临床作用需要进一步研究。
