背景资料：与开放手术相比，微创手术（MIS）在很大程度上依赖于先进的技术，如内窥镜观察系统和创新仪器。该研究的目的是客观地比较三种技术先进的腹腔镜观察系统与目前大多数荷兰医院使用的标准观察系统。研究方法：我们评估了以下先进的腹腔镜观察系统：薄膜晶体管（TFT）显示器，立体内窥镜和图像投影显示器。标准观察系统由单目内窥镜和高分辨率监视器组成。任务完成时间是衡量业绩的尺度。八名具有腹腔镜经验的外科医生参与了实验。结果：立体观察系统的平均任务时间显著大于标准观察系统（p <0.05）。使用TFT显示器和图像投影显示器的平均任务时间与标准观察系统没有显著差异。结论：虽然立体观察系统承诺改善深度感知，TFT和图像投影显示器应该改善手眼协调，但在这个骨盆训练器实验中，这些系统都没有提供比标准观察系统更好的任务性能。
Background: Compared to open surgery, minimally invasive surgery (MIS) relies heavily on advanced technology, such as endoscopic viewing systems and innovative instruments. The aim of the study was to objectively compare three technologically advanced laparoscopic viewing systems with the standard viewing system currently used in most Dutch hospitals. Methods: We evaluated the following advanced laparoscopic viewing systems: a Thin Film Transistor (TFT) display, a stereo endoscope, and an image projection display. The standard viewing system was comprised of a monocular endoscope and a high-resolution monitor. Task completion time served as the measure of performance. Eight surgeons with laparoscopic experience participated in the experiment. Results: The average task time was significantly greater (p <0.05) with the stereo viewing system than with the standard viewing system. The average task times with the TFT display and the image projection display did not differ significantly from the standard viewing system. Conclusion: Although the stereo viewing system promises improved depth perception and the TFT and image projection displays are supposed to improve hand–eye coordination, none of these systems provided better task performance than the standard viewing system in this pelvi-trainer experiment.
