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.

项目概要模拟训练的独特之处在于它能够重复练习各种场景并反映在不危及患者安全的情况下提高性能。手术技能模拟器已成功桥接当前培训模式的差距；然而，这些模拟器无法提供完整的操作经验。与活体患者进行手术接触仍然是临床实践培训的先锋。在下面监督和指导，培训外科医生在住院期间内在地练习和完善患者的技能，让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的外科技术，包括微创颅神经外科技术。提升效率、安全和微创手术训练的全面性，我们建议开发无生命颅骨利用 3D 打印技术中的新颖概念的神经外科模型。我们设计了一个模型来模拟从大脑中排出血凝块，我们建议修改该模型以模拟大脑切除瘤。通过该模型，可以在上岗前获得全面的程序培训和能力手术暴露。我们计划通过比较经验丰富的几个临床指标来验证这个模型外科医生和实习生。我们还将通过测试机械和性能来验证该模型的物理真实性相对于人体组织的成像特性。
