摘要
目的 探讨3D打印结合镜像模型应用于创伤骨科教学的方法及效果.方法 选择在创伤骨科实习的学生34名,采用随机分组法分为实验组(17名,3D打印结合镜像模型辅助带教)和对照组(17名,常规带教),比较两组学生的创伤骨科实习效果和带教效果.结果 实验组学生的骨科解剖理解能力、骨折损伤鉴别能力、影像资料分析能力以及骨科手术设计能力得分均高于对照组,差异均有统计学意义(t分别=4.93、4.32、6.80、4.06,P均＜0.05).实验组学生在专注度、兴趣度、参与度的评分及满意度均高于对照组,差异均有统计学意义(t分别=7.32、6.63、7.49、4.12,P均＜0.05).结论 3D打印结合镜像模型在创伤骨科教学培训中与传统教学方式相比,能够提高学生的学习热情和教学质量,有利于对四肢创伤骨科疾病的讲解和治疗方案的设计规划,更快地提高学生对手术操作及重点内容的理解及掌握.
Abstract
Objective To explore the methods and effects of 3D printing combined with mirror models in orthopedic trauma teaching.Methods A total of 34 students who were selected for internship in the department of traumatology and orthopedics were randomly divided into the experimental group(17 students)who received 3D printing combined with mirror model assisted teaching and the control group(17 students)who received conventional teaching.The effects of traumatic orthopedics practice and teaching were compared between the two groups.Results The students in the experi-mental group had higher scores in orthopedic anatomy understanding ability,fracture injury identification ability,imaging data analysis ability and orthopedic surgery design ability than those in the control group,and the differences were statis-tically significant(t=4.93,4.32,6.80,4.06,P＜0.05).The scores of concentration,interest,participation and satisfaction of the experimental group were higher than those of the control group,and the differences were statistically significant(t=7.32,6.63,7.49,4.12,P＜0.05).Conclusion Compared with traditional teaching methods,3D printing combined with mirror model can improve students'learning enthusiasm and teaching quality in traumatic orthopedics teaching training,which is conducive to the explanation of orthopedics diseases of limbs trauma and the design and planning of treatment programs,and improve students'understanding and mastery of surgical operations and key contents faster.
