Recently a number of manufacturers have developed three-dimensional (3-D) video systems which significantly improve visualization and enhance the ability of the surgeon to perform delicate endoscopic dissection and suturing. These 3-D video systems may also improve the education of surgeons-in-training as they would have a better understanding of three-dimensional anatomy during laparoscopic surgery. Most of the 3-dimensional stereoendoscopic video systems currently available have four basic principles of stereoendoscopic image processing in common: image capture, conversion of 60-120 Hz images; presentation of left and right images on a single monitor; and separation of the left and right eye images. Skill tests performed assessing laparoscopic suturing and knot tying have demonstrated a 25% increase in speed and accuracy of these laparoscopic tasks when utilizing a three-dimensional video imaging greatly facilitates the efficiency of endoscopic reconstructive procedures. While three-dimensional video imaging systems are more costly than conventional two-dimensional video equipment, the enhanced depth perception produced by 3-D endoscopes has been demonstrated to improve the performance of minimally invasive surgical procedures.
最近，一些制造商开发了三维（3-D）视频系统，这些系统显著改善了可视化效果，并增强了外科医生进行精细内镜解剖和缝合的能力。这些3-D视频系统还可能改善外科住院医师的培训，因为他们在腹腔镜手术过程中能更好地理解三维解剖结构。目前市面上的大多数三维立体内镜视频系统都有四个共同的立体内镜图像处理基本原理：图像采集、60 - 120赫兹图像的转换；在单个显示器上呈现左右图像；以及分离左右眼图像。在评估腹腔镜缝合和打结的技能测试中，使用三维视频成像时，这些腹腔镜任务的速度和准确性提高了25%，极大地促进了内镜重建手术的效率。虽然三维视频成像系统比传统二维视频设备成本更高，但3-D内镜产生的增强深度感知已被证明能提高微创手术的性能。
