3D打印模型在髋关节翻修临床教学中的应用

Application of 3D printed model in clinical teaching of hip revision

目的 评估3D打印模型在髋关节翻修临床教学方面的效果,改进教学质量。 方法 选取北京大学第三医院进行外科专业规范化培训的学员50名,分为对照组和试验组,每组各25人。对照组采用传统教学,试验组采用3D打印模型辅助教学。培训结束后,对两组成员进行专业理论测试和教学评估问卷调查,并对两组学员的专业理论测试成绩、教学满意度和学习兴趣做统计学分析。采用SPSS 18.0进行 t 检验。 结果 试验组学生的专业理论笔试成绩(84.60±5.76)分高于对照组(78.20±6.90)分,差异有统计学意义( P <0.05)。试验组学生的教学满意度[(4.72±0.46)vs.(4.28±0.61)]和学习兴趣[(4.76±0.44)vs.(4.28±0.54)]均优于传统教学组,差异有统计学意义( P <0.05)。 结论 3D打印模型辅助教学能有效加深学生对髋关节结构的理解,提高教学质量,增强学习的积极性和主动性。

Objective To evaluate the effect of 3D printed models assisted teaching method on clinical teaching of hip revision and improve the teaching quality.Methods Fifty students who were in the standardized training for surgical specialty from Peking University Third Hospital were divided into a control group and an experimental group,with 25 students in each group.The control group was taught by traditional methods,while the experimental group was taught by 3D printed models.After the training,professional theory test and teaching evaluation questionnaire survey were conducted among the members of the two groups,and statistical analysis was made on the students'professional theory test scores,learning interests and teaching satisfaction.SPSS 18.0 was used for t test.Results The theoretical scores of the experimental group[(84.60±5.76)points]were higher than those of the control group[(78.20±6.90)points],and the difference was statistically significant(P<0.05).The teaching satisfaction and learning interest of the experimental group were both better than those of the control group[(4.72±0.46)vs.(4.28±0.61),(4.76±0.44)vs.(4.28±0.54)],with statistically significant differences(P<0.05).Conclusion The 3D printed model assisted teaching can effectively deepen students'understanding of hip joint structure,improve the teaching quality,and enhance their enthusiasm and initiative in learning.
