Three-dimensional visualisation of the operative field is an important requisite for precise and fast handling of open surgical operations. Up to now it has only been possible to display a two-dimensional image on the monitor during endoscopic procedures. The increasing complexity of minimal invasive interventions requires endoscopic suturing and ligatures of larger vessels which are difficult to perform without the impression of space. Three-dimensional vision therefore may decrease the operative risk, accelerate interventions and widen the operative spectrum. In April 1992 a 3-D video system developed at the Nuclear Research Center Karlsruhe, Germany (IAI Institute) was applied in various animal experimental procedures and clinically in laparoscopic cholecystectomy. The system works with a single monitor and active high-speed shutter glasses. Our first trials with this new 3-D imaging system clearly showed a facilitation of complex surgical manoeuvres like mobilisation of organs, preparation in the deep space and suture techniques. The 3-D-system introduced in this article will enter the market in 1993 (Opticon Co., Karlsruhe, Germany.
手术视野的三维可视化是精确、快速进行开放手术操作的重要前提条件。到目前为止，在内镜手术过程中，仅能在监视器上显示二维图像。微创干预的复杂性不断增加，需要对较大血管进行内镜缝合和结扎，而没有空间感的话这些操作很难进行。因此，三维视觉可能会降低手术风险、加快干预速度并拓宽手术范围。1992年4月，德国卡尔斯鲁厄核研究中心（IAI研究所）研发的一种三维视频系统被应用于各种动物实验程序以及腹腔镜胆囊切除术的临床实践中。该系统通过一台监视器和有源高速快门眼镜工作。我们使用这种新型三维成像系统的首次试验清楚地表明，它便于进行诸如器官游离、深部空间的准备和缝合技术等复杂的外科操作。本文介绍的三维系统将于1993年进入市场（德国卡尔斯鲁厄的Opticon公司）。
