PURPOSE
In this study, a simulator for training lateral ventricular puncture (LVP) was developed using three-dimensional (3D) printing technology, and its function of improving the skills of LVP in young interns was evaluated.
METHODS
A virtual 3D craniocerebral simulator of a 51-year-old female patient with hydrocephalus was reconstructed with 3D printing technology. The anatomical and practical validity were assessed by all interns on a 13-item Likert scale. The usefulness of this simulator was evaluated once a week by two neurosurgeons, based on the performance of the interns, using the objective structured assessment of technical skills (OSATS) scale.
RESULTS
The Likert scale showed that all participants agreed with the overall appearance of the simulator. Also, the authenticity of the skull was the best, followed by the lateral ventricles, analog generation system of intraventricular pressure, cerebrum, and the scalp. This simulator could help the participants' learning about the anatomy of the lateral ventricle, effective training, and repeating the steps of LVP. During training, the interns' ratio of success in LVP elevated gradually. At each evaluation stage, all mean performance scores for each measure based on the OSATS scale were higher than the previous.
CONCLUSIONS
The 3D printed simulator for LVP training provided both anatomical and practical validity, and enabled young doctors to master the LVP procedures and skills.
目的
在本研究中，利用三维（3D）打印技术开发了一种用于训练侧脑室穿刺（LVP）的模拟器，并评估其在提高年轻实习生LVP技能方面的作用。
方法
采用3D打印技术重建了一名51岁脑积水女性患者的虚拟3D颅脑模拟器。所有实习生采用13项李克特量表对其解剖学和实际有效性进行评估。两位神经外科医生每周根据实习生的表现，使用客观结构化技术技能评估（OSATS）量表对该模拟器的实用性进行一次评估。
结果
李克特量表显示，所有参与者均认可模拟器的整体外观。此外，颅骨的真实性最佳，其次是侧脑室、脑室内压力模拟生成系统、大脑和头皮。该模拟器有助于参与者了解侧脑室的解剖结构、进行有效训练并重复LVP步骤。在训练过程中，实习生LVP的成功率逐渐提高。在每个评估阶段，基于OSATS量表的各项指标的所有平均表现得分均高于前一阶段。
结论
用于LVP训练的3D打印模拟器具有解剖学和实际有效性，能够使年轻医生掌握LVP操作和技能。
