【摘要】 本研究利用正常成年人的脑部CT数据,经计算机三维重建,制备数字化人脑,用3D打印技术打印出人端脑模型,将其用于人体解剖学的实验教学中。将我校护理学专业大一学生随机分为实验组(27人)和对照组(26人),在端脑理论授课后,实验组用3D打印端脑模型和端脑标本,对照组仅用端脑标本,自主学习30分钟后,进行无记名测试。随后对实验组学生进行无记名问卷调查,了解学生对3D打印在解剖学教学中应用的意见。结果显示,实验组学生的测试平均成绩显著高于对照组(P<0.01),80分及以上学生人数明显多于对照组。所有实验组学生认为3D打印的端脑模型使用方便。大多数赞同打印模型与标本形态结构一致,接近90%的学生认为打印模型能提高学习解剖学的兴趣,促进对解剖空间结构的理解,促进解剖学知识的记忆,可推广应用到解剖学其他章节的学习中。本研究证实3D打印可提高解剖学实验教学的质量。更多还原

【Abstract】 The brain CT data of normal adults were used for 3 Dreconstruction to prepare the digitized human brain,and the human brain model was printed with 3 Dprinting technology.The models were used in the experimental teaching of human anatomy in undergraduates major in nursing.The students majoring in nursing in our school were randomly divided into an experimental group(27 students)and a control group(26 students).After teaching the telencephalon theory,both group studied the telencephalon 30 min,the experimental group using 3D printing telencephalon model and telencephalon specimen,while the control group only using telencephalon specimen.A total of 10 structures on the surface of the human telencephalon were tested.Then an anonymous questionnaire survey was conducted among the experimental group to find out the students’ opinions on the application of 3D printing in anatomy teaching.The results showed that the average score of the experimental group was significantly higher than that of the control group(P <0.01),and the number of students with higher scores was higher than that of the control group.All the students in the experimental group thought the 3D printed brain model was convenient to use.Most students agreed that the printed model were consistent with the specimen’s morphological structure,and nearly 90% of the students believed that the printed model could improve the interest in studying anatomy,promote the understanding of anatomical spatial structure,and promote the memory of anatomical knowledge,and could be generalized and applied to the study of other parts of anatomy.This study proves that 3D printing can improve the quality of experimental teaching of human anatomy.更多还原
