三维（3D）打印模型被广泛接受用于先天性心脏病的各种外科手术的训练;然而，它们的物理特性被认为是次优的。我们使用一种新的“分离和组装”策略创建了硅胶成型模型，并将其与传统3D打印模型的动手培训适用性进行了比较。使用了2例大动脉转位患者的计算机断层扫描成像数据。将心脏分成多个部分（心房、心室、大动脉、冠状动脉和瓣膜），并创建每个部分的模具。使用粘合剂组装通过硅树脂模塑复制的部件。在一个在线课程中，2个硅胶成型模型和1个3D打印模型用于培训34名外科医生。向这些外科医生分发了一份问卷，旨在评估动脉调转手术（阿索）模型的适用性。硅胶模塑模型显示出出色的解剖细节、高弹性和高抗撕裂性。基于50个模型的生产，每个模型的成本与3D打印模型相比，硅胶成型模型略高。所有完成问卷调查的26名外科医生都报告说，硅胶成型模型提供了足够的解剖信息，但只有19%的人表示3D打印模型也是如此。所有外科医生还认为硅胶模型在通过针头、切割血管、切除冠状动脉按钮时都是真实的，而3D打印模型的真实性低于46%。硅树脂成型的模型的阿索是可行的，通过应用“分型和组装”的战略。硅胶模塑模型具有优异的物理性能，远远上级用于手术模拟的3D打印模型。
Three-dimensional (3D) printed models are widely accepted for use in training of various surgical procedures for congenital heart disease; however, their physical properties have been considered suboptimum for procedures. We created silicone molded models produced using a novel “parting and assembly” strategy and compared their suitability for hands-on training with that of conventional 3D printed models. Computed tomography imaging data from 2 patients with transposition of the great arteries were used. The heart was divided into multiple parts (atria, ventricles, great arteries, coronary arteries, and valves), and molds of each part were created. The parts reproduced by silicone molding were assembled using an adhesive agent. In an online course, 2 silicone molded models and 1 3D printed model were used for training of 34 surgeons. A questionnaire was distributed to these surgeons aimed at assessing the suitability of the models for the arterial switch operation (ASO). The silicone molded models showed excellent anatomic detail, high elasticity, and high resistance to tearing. The cost per model, based on the production of 50 models, was slightly higher for the silicone molded models compared with the 3D printed models. All 26 surgeons who completed the questionnaire reported that the silicone molded models provided sufficient anatomic information, but only 19% said the same for the 3D printed models. All surgeons also considered the silicone models to be realistic when passing a needle, cutting vessels, suturing, and excision of the coronary buttons, as opposed to <46% for the 3D printed models. Silicone molding of models for the ASO is feasible by applying a “parting and assembly” strategy. Silicone molded models provide excellent physical properties that are far superior to those of 3D printed models for surgical simulation.
