项目摘要

Project Summary Simulation training is unique in its ability for repetitive practice of a wide variety of scenarios and to reflect on performance without jeopardizing a patient’s safety. Surgical skills simulators have been successful in bridging gaps of the current training model; however, these simulators fall short of offering a complete operative experience. Operative exposure with live patients still remains the vanguard of hands-on clinical training. Under supervision and guidance, training surgeons inherently practice and refine skills on patients during residency, exposing them to unnecessary risks. Novel simulation tools are needed to both validate and implement novel surgical techniques, including those for minimally invasive cranial neurosurgery. To enhance the efficiency, safety and comprehensiveness of minimally invasive surgical training, we propose to develop an inanimate cranial neurosurgery model utilizing novel concepts in 3D printing technology. We have engineered a model to simulate evacuation of a blood clot from the brain, and we propose to modify this model to simulate resection of a brain tumor. Through this model, comprehensive procedural training and competence can be achieved prior to operative exposure. We plan to validate this models by comparing several clinical metrics in experienced surgeons and trainees. We will also validate the physical realism of this model by testing the mechanical and imaging properties relative to human tissue.

项目摘要模拟培训的重复练习能力是独一无二的，并反映关于性能，而不会危及患者的安全。手术技能模拟器已成功桥接当前培训模型的空白；但是，这些模拟器未能提供完整的操作经验。现场患者的手术暴露仍然是动手临床培训的先锋。在下面监督和指导，培训外科医生固有地练习并在居住期间对患者的技能提高技能，使他们面临不必要的风险。需要新颖的模拟工具来验证和实施新颖手术技术，包括用于微创颅神经外科手术的技术。为了提高效率，安全性以及微创手术训练的全面性，我们建议开发无生命的颅骨神经外科手术模型利用3D打印技术中的新概念。我们已经设计了一个模型来模拟从大脑中撤离血块，我们建议修改该模型以模拟大脑的切除瘤。通过这种模型，可以在手术曝光。我们计划通过比较经验丰富的几个临床指标来验证该模型外科医生和学员。我们还将通过测试机械和成像相对于人体组织的成像特性。
