Because of the lack of depth perception in current two-dimensional endoscopic video systems, the performance of fine motor movements is impaired. Endoscopic surgeons are generally able to cope with this limitation, and the performance of complex procedures becomes easy with experience. To assess the value of three-dimensional vision, two groups of surgeons, with and without experience in endoscopic surgery, underwent dexterity tests at a simulator. Data from use of two- and three-dimensional video systems were analysed and are discussed in this paper. The three-dimensional system improved the ability to perform endoscopic procedures, particularly when the highest degree of hand-eye coordination was needed. A common sensation of ocular fatigue, related to the prolonged use of this equipment, may limit its usefulness in advanced endoscopic procedures.
由于当前二维内镜视频系统缺乏深度感知，精细运动的表现受到损害。内镜外科医生通常能够应对这一限制，并且随着经验的积累，复杂手术的操作会变得容易。为了评估三维视觉的价值，两组外科医生，一组有内镜手术经验，一组没有，在模拟器上进行了灵巧性测试。本文分析并讨论了使用二维和三维视频系统的数据。三维系统提高了进行内镜手术的能力，特别是在需要最高程度的手眼协调时。与长时间使用该设备相关的常见眼部疲劳感，可能会限制其在高级内镜手术中的实用性。
