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

这个小型企业创新研究(SBIR)第一阶段项目的更广泛的影响/商业潜力是通过创造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。拟议的项目将证明在模拟的开放手术系统上进行渐进式技能教育和量化评估的可行性。这个项目将开发一个高保真的模块系统和合成血管系统，以有效地培训开放式血管手术的外科医生。这个小企业创新研究(SBIR)第一阶段项目将促进支持外科培训的教育工具的开发。该设备必须提供循序渐进的技能教育，让用户接触到广泛的开放式手术程序，并提供客观的反馈指标。这项拟议的研究将首先调查开发各种模拟血管组件的可行性，包括那些有异常的组件，然后将它们整合到台式系统中。综合训练模型将由实习外科医生使用两极标度法进行评估。人造血管组织的机械性能将被测量，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。这些指标将在一个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估。预期的结果是具有与活组织相似的机械性能的合成血管材料，经专家外科医生小组验证为现实的手术模型，以及具有能够区分用户技能水平的传感器和组件的系统。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

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.
