基于文献分析、小组讨论、德尔菲法(专家咨询法)等方法,确定了3D腔镜系统评价指标,制定了评价标准及专家评价表,邀请多家医院、多个研究领域的临床专家对品牌A和品牌B两款产品基于猪模型以及腔镜模拟训练器进行对比评价.在该研究样本量下,结果显示:在动物实验中品牌A共计25项指标中的24项指标评分结果与品牌B没有显著性差异,在立体感这一指标上显著优于品牌B;在腔镜模拟训练器下,品牌A的视野、清晰度、景深等15项指标的评分结果与品牌B差异无统计学意义,但分辨能力、抗反光能力、图像保真性、视疲劳以及总体印象这5项指标的评分与品牌B差异有统计学意义.该研究采用t检验统计学方法分别对比了在动物实验研究中以及腔镜模拟训练器下,专家对品牌A和品牌B各项指标的评分结果以及参评专家对两款设备的总体表现、景深等方面发表的个人建议,可为企业在设备功能和性能改进方面提供参考.
Comparative Evaluation of 3D Endoscopic Systems Based on Pig Model and Endoscopic Simulation Trainer
Based on the methods of literature analysis,group discussion and Delphi expert consultation,this study determined the evaluation index of 3D endoscopic system,formulated the evaluation criteria and expert evaluation table,and invited clinical experts from multiple hospitals and multiple research fields to compare and evaluate brand A and brand B products under pig model and endoscopic simulation trainer.Under the sample size of this study,the results showed that there was no significant difference in the scores of 24 indicators among the 25 indicators of brand A in animal experiments,which was significantly better than brand B in the three-dimensional sense.Under the cavity mirror simulation trainer,there is no significant difference between brand A and brand B in the scores of 15 indicators such as visual field,clarity and depth of field,but there are significant differences between brand A and brand B in the five indicators of resolution,anti-reflection ability,image fidelity,visual fatigue and overall impression.In this study,T-test statistical method was used to compare the scoring results of experts on the indicators of brand A and brand B in animal experimental research and endoscopic simulation training device,as well as the personal suggestions of participating experts on the overall performance and depth of field of the two devices,which can provide reference for enterprises in the improvement of equipment function and performance.
