混合现实技术在经皮椎间孔入路腰椎间盘切除术临床教学中的应用
|
摘要
目的旨在探索混合现实技术在经皮椎间孔入路腰椎间盘切除术临床教学中的应用。方法通过与清华大学团队合作,将经皮椎间孔入路腰椎间盘切除术通过混合现实技术得以呈现。从北京协和医院外科轮转住院医师和协和八年制实习生中随机选取混合现实组和传统教学组各12人,保证年龄、性别、年资匹配。两组学生分别采用传统教学及应用混合现实技术的授课方式。课后针对授课的交互性、趣味性、三维空间想象及对知识的理解程度进行问卷调研和课后测试。结果本研究率先运用混合现实技术,以经皮椎间孔入路腰椎间盘切除术为例,采用头戴式虚拟现实设备创设学习情境,将三维立体的空间结构直观呈现出来。两组学生在对知识的掌握程度上无明显差异,但混合现实组在学习的主动性、趣味性和三维立体想象力等方面具有显著优势。结论混合现实技术在医学教学中应用潜力巨大、前景广阔,可提高医学教学的形象化、交互性和三维空间感。混合现实技术结合力反馈,进行专科医师的模拟训练具有重要的发展前景。
Objective To explore the application of mixed reality technique in the clinical teaching of percutaneous endoscopic transforaminal discectomy. Methods Collaborating with the team of Tsinghua University, percutaneous endoscopic transforaminal discectomy was presented through mixed reality technology. The subjects were selected from the resident doctor and intern in the surgical department of Peking Union Medical College Hospital, and randomly divided into mixed reality group and traditional teaching group(12 for each). After clinical teaching, questionnaire surveys and tests of the interactivity, interest, three-dimensional imagination, and understanding of knowledge were performed in two groups. Results There was no significant difference in the understanding of basic knowledge between the two groups, but the mixed reality group had significant advantages in learning initiative, interactivity, interest stimulation and three-dimensional imagination. Conclusions The application of mixed reality inmedical teaching has great potential and broad prospects. Visualization, interactivity and three-dimensional imagination could be improved by medical teaching with mixed reality. Mixed reality combined with force feedback technology has significant value in simulation training of specialist physicians.
