背景考虑到肺结构的复杂性和胸镜手术的难度，模拟培训对于初级外科医生来说是至关重要的。在这里，我们的目的是利用3D打印技术结合合成材料来设计一种高保真的肺部模型，以模拟真实的人类肺部。合成材料被用来构建肺实质、血管和支气管。然后，参与者(高级外科医生、初级外科医生和医学生)对模型的视觉、触觉和操作特征进行评估，并要求他们完成专门设计的调查问卷。结果成功地制作了由合成材料制成的右肺3D打印模型。30名受试者(10名高级外科医生、10名初级外科医生和10名医学生)参加了我们的研究。高级外科医生、初级外科医生和医学生的平均视觉评价得分分别为3.970.61、4.56+/-0.58、4.76+/-0.49。平均触觉评分分别为3.40±0.50、4.13±0.68、4.00±0.64。平均手术评分分别为3.33±0.83、3.93±0.66、4.03±0.66。高级外科医生组得分明显低于其他两组。结论所建立的3D打印肺模型具有较高的逼真度，可作为未来外科培训的模拟器。
Background Considering the complexity of lung structures and the difficulty of thoracoscopic surgery, simulation-based training is of paramount importance for junior surgeons. Here, we aim to design a high-fidelity lung model through utilizing the three-dimensional (3D) printing technology combined with synthetic materials to mimic the real human lung.Methods The 3D printed lung model was manufactured based on the computed tomography images of a randomly selected male patient. Synthetic materials were used for the construction of lung parenchyma, blood vessels, and bronchi. Then, the model was assessed in terms of its visual, tactile, and operational features by participants (the senior surgeons, junior surgeons, and medical students), who were asked to complete the specially designed survey-questionnaires.Results A 3D printed model of the right lung made of synthetic materials was successfully fabricated. Thirty subjects participated in our study (10 senior surgeons, 10 junior surgeons, and 10 medical students). The average visual evaluation scores for senior surgeons, junior surgeons, and medical students were 3.970.61, 4.56 +/- 0.58, 4.76 +/- 0.49, respectively. The average tactile evaluation scores were 3.40 +/- 0.50, 4.13 +/- 0.68, 4.00 +/- 0.64, respectively. The average operation evaluation scores were 3.33 +/- 0.83, 3.93 +/- 0.66, 4.03 +/- 0.66, respectively. Significant lower scores were obtained in the group of the senior surgeons compared with the other two groups.Conclusion A high level of fidelity was exhibited in our 3D printed lung model and it could be applied as a promising simulator for the surgical training in the future.
