Physics-Based Simulator to Teach Hands-On Vascular Surgical Skills

描述（由申请人提供）：SimQuest LLC提出开发一种基于物理的血管外科技能培训模拟器，以克服目前体验式血管外科培训的不足。这与国家卫生和社会责任机构的使命相吻合，即促进研究成果的应用并利用资源来满足公共卫生需求，在这种情况下是患者安全。当模拟器完成后，用户将能够练习血管吻合，直到他们表现出熟练。他们将站在手术台上，观看病人解剖结构的立体显示，使用实际的手术工具进行操作，并在手术过程中遇到与现实生活中相同的皮肤和血管阻力——这些效果是由SimQuest在联邦基金资助下开发的先进的生物组织和缝合材料特性以及低成本触觉技术实现的。第二阶段项目的第一个目标是继续为外科、学术和学习科学建立一个框架和过程，以支持这种最终用户驱动的仿真开发及其验证。这将包括继续与血管外科教育和认证领域的领导者建立联系；让学习科学家和经验丰富的外科培训师指导、审查和验证目标、指标和教学内容；让这些专家参与整个迭代设计过程；基准测试和概念验证。第二个目标是创建虚拟现实模拟器，其中包括模拟程序所需的技术组件；整合指标；使使用者能够在手术处理血管和缝合吻合时犯错误并从中恢复；然后构建、测试和完善原型。最后的目标是验证

DESCRIPTION (provided by applicant): SimQuest LLC proposes to develop a physics-based vascular surgery skills training simulator that will overcome current shortcomings in experiential open vascular surgery training. This dovetails with the mission of the NHLBI to promote application of research results and leverage resources to address public health needs, in this case, patient safety. When the simulator is complete, users will be able to practice vascular anastomosis until they are shown to be proficient. They will stand as they would at an operating table, view a stereo display of patient anatomy, which they manipulate using actual surgical tools, and encounter the same resistance of skin and vessels during the procedure that they would in real life - effects made possible by advanced, biofidelic tissue and suture material properties and low-cost haptics technology developed by SimQuest with federal funding. The first objective of this Phase II project is to continue to establish a framework and process for surgical, academic, and learning sciences' support for this end-user-driven simulation development and for its validation. This will include continued networking with leaders in vascular surgery education and certification; having learning scientists and experienced surgical trainers dictate, review and validate the goals, metrics, and didactic content; involvement of these experts throughout the iterative design process; and benchmarking and validation of concept. The second objective is to create the virtual reality simulator, which includes the technical components required to simulate the procedure; integrate the metrics; make it possible for users to make and recover from errors in surgical handling of vessels and suture anastomosis; and build, test, and refine the prototype. The final objective will be to validate the curriculum/simulator prototype using state-of-the-science validation methodologies directed by an authoritative academic resource. The proposed project will encompass the necessary research to provide training for all open vascular procedures on an open-source platform and will provide the exemplar procedure of end-to-end anastomosis. This will potentially make it clinically useful to licensing and accreditation bodies. Letters of support from the leadership of all the US national societies involved in vascular surgery training, education, and certification are a testament to the importance of this project to surgical skill acquisition, documentation of proficiency, certification, and patient safety.
