摘要
目的引入3D打印模型,探讨互联网+3D打印模型在腹腔镜外科基本技能培训中的应用。方法以24名接受外科住院医师规范化培训的学员作为受试者,并随机分为4组。A、B、C、D组分别接受传统模型、动物组织、3D打印模型、互联网+3D打印模型的腹腔镜下基本技能训练,并采用动物组织样本和手术技能客观结构化评估量表(OSATS)评估训练效果。评估结束后,A、B、C三组追加其他两种模型培训,然后采用Likert五分类量表,评估传统模型和3D打印模型与真实组织的相似度。结果3D打印模型在视觉、触觉、韧度、进针力度、打结张力方面均优于传统模型,更接近于真实组织。A、B、C、D组OSATS评分分别为17.92±0.74,22.17±1.60,21.92±1.20,21.58±1.07,组间比较差异有统计学意义(F=22.5,P<0.01)。结论互联网+3D打印模型明显优于传统模型,可以达到与采用动物组织或3D打印模型进行面授培训相当的培训效果。
Objective To discuss the application of internet+3D printing model in basic skills training of laparoscopic surgery.Methods Twenty-four trainees of standardized training of surgical residents were randomly divided into 4 groups.Group A,B,C,and D received basic laparoscopic skills training with traditional model,animal tissue,3D printing model,internet+3D printing model.After training,animal tissue sample and objective structured assessment of technical skills(OSATS)were used to evaluate the training effects.After evaluation,groups A,B and C adopted additional training of other models,then Likert five-category scale was used to evaluate the similarity between traditional models,3D printed models and real organizations.Results The 3D printing model is better than the traditional model and similiar to the real tissue in terms of vision,touch,toughness,needleinsertion force,and knot tension.The OSATS scores in groups A,B,C and D were 17.92±0.74,22.17±1.60,21.92±1.20,21.58±1.07,respectively(F=22.5,P<0.01).Conclusion The internet+3D printing model is significantly better than the traditional model,and can achieve a training effect equivalent to that during face-to-face training using animal tissue or 3D printing model.
