SBIR Phase I: Open Vascular Surgical Training System for Skill Acquisition and Evaluation

这一小型企业创新研究（SBIR）I期项目的更广泛影响/商业潜力是通过创建一种可以培训和评估外科医生的设备来简化手术培训并减少手术并发症的负担。 该项目将证明在模拟开放手术系统上进行渐进式技能教育和定量评估的可行性。该项目将开发高保真模块化系统和合成血管系统，以有效地培训外科医生进行开放血管手术。该小型企业创新研究（SBIR）第一阶段项目将推进开发教育工具，以支持外科手术培训。 该器械必须提供渐进式技能教育，使用户接受全面的开放式外科手术，并提供客观的反馈指标。拟议的研究将首先调查开发各种模拟血管组件的可行性，包括那些异常的组件，然后将它们集成到台式系统中。将由执业外科医生使用双极缩放方法对合成训练模型进行评价。将测量合成血管组织的机械性能，并与活组织进行比较。该项目还将开发用于测量手术性能的组件。这些指标将在一项由经验丰富和缺乏经验的外科医生组成的小组进行的试点研究中进行评价。预期的结果是一种具有与活组织相似机械性能的合成血管材料，由专家外科医生小组验证为真实的手术模型，该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查进行评估，被认为值得支持的搜索.

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is to streamline surgical training and reduce the burden of surgical complications by creating a device that can train and evaluate surgeons. The proposed project will demonstrate the feasibility of progressive skills education and quantitative assessment on a simulated open surgery system. This project will develop a high-fidelity modular system and synthetic vasculature to effectively train surgeons in open vascular surgery.This Small Business Innovation Research (SBIR) Phase I project will advance development of an educational tool to support surgical training. The device must provide progressive skills education, expose users to a comprehensive range of open surgical procedures, and provide objective feedback metrics. The proposed research will first investigate the feasibility of developing a variety of simulated vascular components, including those with abnormalities, and subsequently integrating them into the benchtop system. The synthetic training models will be evaluated by practicing surgeons using a bipolar scaling method. The mechanical properties of the synthetic vascular tissue will be measured and compared to live tissue. This project will additionally develop components to measure surgical performance. The metrics will be evaluated in a pilot study of a panel of experienced and inexperienced surgeons. The anticipated results are a synthetic vascular material with similar mechanical properties as live tissue, surgical models that are validated as realistic by a panel of expert surgeons, and a system with sensors and components that are capable of differentiating between user skill levels.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
