运动跟踪的使用已被证明可以为外科技能培训提供客观的评估。然而,目前的系统需要使用额外的设备或专门的腹腔镜仪器和摄像机来提取数据。本研究的目的是确定使用基于软件的解决方案来提取数据的可能性。6名专家和23名新手参与者在手术室进行了基本的腹腔镜胆囊切除术。使用Kinemia 0.8.15分析所记录的视频,并且以下参数计算路径长度、平均仪器移动和突然或极端移动的数量。分析的数据显示,与新手相比,专家的路径长度明显更短(中位数127 cm vs. 187 cm,p = 0.01),平均运动更小(中位数0.40 cm vs. 0.32 cm,p = 0.002),突然运动更少(中位数14.00 vs. 21.61,p = 0.001)。使用基于软件的视频运动跟踪进行腹腔镜胆囊切除术是一种简单可行的方法,可以客观评估手术性能。它提供了专家和新手性能之间的明确区分。
The use of motion tracking has been proved to provide an objective assessment in surgical skills training. Current systems, however, require the use of additional equipment or specialised laparoscopic instruments and cameras to extract the data. The aim of this study was to determine the possibility of using a software-based solution to extract the data. 6 expert and 23 novice participants performed a basic laparoscopic cholecystectomy procedure in the operating room. The recorded videos were analysed using Kinovea 0.8.15 and the following parameters calculated the path length, average instrument movement and number of sudden or extreme movements. The analysed data showed that experts had significantly shorter path length (median 127 cm vs. 187 cm, p = 0.01), smaller average movements (median 0.40 cm vs. 0.32 cm, p = 0.002) and fewer sudden movements (median 14.00 vs. 21.61, p = 0.001) than their novice counterparts. The use of software-based video motion tracking of laparoscopic cholecystectomy is a simple and viable method enabling objective assessment of surgical performance. It provides clear discrimination between expert and novice performance.
