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.
