Single-port access systems (SPASs) are currently used in human and veterinary surgeries. However, they pose technical challenges, such as instrument crowding, intra- and extracorporeal instrument collision, and reduced maneuverability. Studies comparing the maneuverability of the scopes and instruments in different SPASs are lacking. This study aimed to compare the maneuverability of three different SPASs: the Covidien SILS-port, Storz Endocone, and glove port. A clear acrylic box with artificial skin placed at the bottom was used to mimic the abdominal wall and cavity. The three SPASs were placed from below, and a 10-mm endoscope and 5-mm instrument were introduced. A motion analysis system consisting of 18 cameras and motion analysis software were used to track the movement of the endoscope and instrument, to determine the volume of the cone-shaped, three-dimensional figures over which movement was possible, with higher values indicating greater maneuverability. The Mann-Whitney U test was used for the analysis. The maneuverability of the endoscope alone was significantly higher in the glove port system than in the other two SPASs. When inserting an additional instrument, the maneuverability significantly decreased in the SILS-port and Endocone, but not in the glove port. The highest maneuverability overall was found in the glove port.
单孔接入系统（SPASs）目前用于人类和兽医外科手术。然而，它们带来了一些技术挑战，如器械拥挤、体内外器械碰撞以及可操作性降低。缺乏比较不同SPASs中内镜和器械可操作性的研究。本研究旨在比较三种不同的SPASs：柯惠SILS端口、史托斯Endocone和手套端口的可操作性。使用底部放置有人造皮肤的透明丙烯酸盒来模拟腹壁和腹腔。从下方放置这三种SPASs，并插入一个10毫米的内窥镜和一个5毫米的器械。使用由18台摄像机和运动分析软件组成的运动分析系统来跟踪内窥镜和器械的运动，以确定可能进行运动的锥形三维图形的体积，值越高表明可操作性越强。采用曼-惠特尼U检验进行分析。仅在内窥镜方面，手套端口系统的可操作性显著高于其他两种SPASs。当插入额外器械时，SILS端口和Endocone的可操作性显著下降，但手套端口没有。总体上手套端口的可操作性最高。
