3D技术在经皮椎体成形术教学中的应用

The Use of 3D Technology in the Teaching of Percutaneous Vertebro Plasty

目的 探讨将3D打印模型用于经皮椎体成形术教学的应用价值。方法 选取2020年9月—2021年8月在本院及联合培养基地进行外科专业的规范化培训的学员50名作为研究对象,按照数字表法随机分实验教学组和传统教学组。其中,传统教学组采用传统的经皮椎体成形术手术教学方法,即通过普通的训练模型及真实手术案例进行经皮椎体成形术手术教学;实验教学组通过采集患者的MRI、CT数据,经数字医学技术设计、并由3D打印技术制作与患者个性化高精度、高仿真的脊柱模型。对比分析两组学员的教学课时、理论知晓率、操作正确率、考核成绩及教学满意度等指标。结果 实验教学组的教学课时短于传统方法组,实验教学组的理论知晓率、操作正确率、考核成绩及教学满意度均高24于传统方法组,组间差异有显著性意义(P<0.05)。结论 3D技术在经皮椎体成形术教学中的应用效果显著,值得推广应用。

Objective To explore the application of 3D printing model in the teaching of percutaneous vertebro plasty and analyze its application value in the teaching of resident physicians.Methods 50 students who received standardized training of surgical specialty in our hospital and joint training base from September 2020 to August 2021 were selected as the research objects,and were randomly divided into 3D printing experimental group and traditional method group according to digital table method.Among them,25 students in the traditional teaching group were taught by the traditional teaching method of percutaneous vertebro plasty,that is,ordinary training models and real cases.253D printing experimental teaching group collected MRI and CT data of patients,designed by digital medical technology,and produced by 3D printing technology with patients'personalized high-precision and high-simulation spinal models.The teaching hours,theoretical awareness rate,operational accuracy rate,assessment results and teaching satisfaction of the two groups of students were compared and analyzed.Results The teaching hours of the experimental teaching group were shorter than those of the traditional method group,and the theoretical awareness rate,operational accuracy rate,assessment results and teaching satisfaction of the experimental teaching group were 24 higher than those of the traditional method group,with significant differences between the groups(all P<0.05).Conclusion The application of 3D technology in the teaching of percutaneous vertebro plasty is significant,and it is worth popularizing.
