The broader impact/commercial potential of this I-Corps project is to make an impact on the minimally invasive surgical systems market, which is greater than $24 billion globally and is projected to grow to more than $40 billion by 2025. The desire for increasingly smaller incisions leads to a need for decreased size and increased functionality of laparoscopic surgical tools. The proposed instruments combine multiple laparoscopic surgical tools (e.g. graspers, endoscopes, and sealers) into a single instrument, reducing the time (and associated cost) of switching instruments. The technology enables multiple tools to be inserted into the surgical space through a single incision, which reduces the number of incisions, operating time, recovery time, and patient pain, while also improving cosmetics. This product could also decrease costs and make minimally invasive surgical systems more affordable for healthcare systems and patients worldwide.This I-Corps project will evaluate creating next-generation minimally invasive surgery instruments by applying fundamental research in developable mechanisms. The proposed laparoscopic instruments take advantage of developable mechanisms' conforming and emerging ability and combine multiple surgical instruments into a single instrument, thereby decreasing the number of cannulas (surgical rods) needed to perform a surgery and the number of incisions required. Fewer incisions leads to faster recovery time, less pain, and improved cosmetics. By integrating multiple instruments into a single unit, this technology will also be able to decrease the number of units required for surgical procedures and thereby decrease instrument and sterilization costs. Developable mechanisms are a new class of kinematic mechanism that can conform to or be embedded in developable surfaces. Developable mechanisms are a simple, clean way to add functionality to existing shafts or tubes without adding material or increasing complexity.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.

I-Corps 项目更广泛的影响/商业潜力是对微创手术系统市场产生影响，该市场全球规模超过 240 亿美元，预计到 2025 年将增长到 400 亿美元以上。切口导致需要减小腹腔镜手术工具的尺寸并增加其功能。所提出的器械将多个腹腔镜手术工具（例如抓紧器、内窥镜和密封器）组合成单个器械，从而减少了切换器械的时间（和相关成本）。该技术能够通过一个切口将多个工具插入手术空间，从而减少切口数量、手术时间、恢复时间和患者疼痛，同时还改善了美观。该产品还可以降低成本，使全球医疗保健系统和患者更负担得起微创手术系统。该 I-Corps 项目将通过应用可开发机制的基础研究来评估创建下一代微创手术器械。所提出的腹腔镜器械利用可开发机构的顺应性和新兴能力，并将多个手术器械组合成单个器械，从而减少进行手术所需的插管（手术杆）的数量和所需的切口的数量。更少的切口可以加快恢复时间、减少疼痛并改善外观。通过将多个器械集成到一个单元中，该技术还能够减少外科手术所需的单元数量，从而降低器械和灭菌成本。 可展机构是一类新型运动机构，可以符合或嵌入可展表面。可开发的机制是一种简单、干净的方法，可以在不增加材料或增加复杂性的情况下向现有轴或管添加功能。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标准进行评估，被认为值得支持。
