DESCRIPTION (provided by applicant): MCNC-RDI and InnerOptic are proposing research and development of new technologies that will build a real-time three-dimensional (3-D) depth extraction laparoscope for use in minimally invasive surgery. The proposed bioengineering research is highly innovative, proposing a high impact in the vital area of visualizing an internal (minimally invasive) surgery site as if it were an open surgery site. If successful, the 3-D depth extraction laparoscope could be a revolutionary surgical tool for the over two million laparoscopic surgeries performed annually in the U.S. alone. This technology is high-risk in terms of its innovative three dimensional perspective of internal organs, versus the traditional two dimensions, which would significantly improve surgeons' tool maneuverability around delicate internal organs during operations. The research design can be grouped into three phases. Phase I will be the planning and design of a specialized optical device, the Electrostatic Actuator (Artificial Eyelid) to meet the structured light pattern requirements of the InnerOptic's novel 3-D laparoscope. Phase II will be the fabrication of an Artificial Eyelid shutter array, a corresponding opto-mechanical mounting subsystem, and a high-voltage electronic driving board to control the position of the eyelids in the array. Phase III will prototype, integrate, and test the 3D laparoscope using the Artificial Eyelid transmissive display element and driver circuitry to demonstrate structured light patterns at rates required for surgery. A key requirement for a medical 3D laparoscope is the creation of structured light patterns in a highly optically efficient manner to obtain sufficient illumination from a compact, collimated light source. The Artificial Eyelid has been identified as an excellent solution to this requirement. Integration of the two technologies is conceptually feasible and would provide the most effective bioengineering method to achieve the visual imaging modalities surgeons require for their daily laparoscopic and endoscopic operation.

描述（由申请人提供）： MCNC-RDI和InnerOptic正在提议研究和开发新技术，以构建用于微创手术的实时三维（3-D）深度提取腹腔镜。拟议的生物工程研究是高度创新的，提出了一个高度影响可视化的内部（微创）手术部位，如果它是一个开放的手术部位的重要领域。如果成功的话，3D深度提取腹腔镜可能成为一种革命性的手术工具，仅在美国每年就有超过200万例腹腔镜手术。该技术在其创新的三维内脏透视方面具有高风险，而传统的二维透视将显著提高外科医生在手术期间围绕精细内脏的工具可操作性。研究设计可分为三个阶段。第一阶段将是规划和设计一个专门的光学设备，静电致动器（人工眼睑），以满足InnerOptic的新型3-D腹腔镜的结构光图案要求。第二阶段将是制造一个人造眼睑快门阵列，一个相应的光学机械安装子系统，和一个高压电子驱动板，以控制眼睑在阵列中的位置。第三阶段将使用人工眼睑透射显示元件和驱动电路对3D腹腔镜进行原型设计、集成和测试，以展示手术所需速率的结构光图案。医疗3D腹腔镜的关键要求是以高度光学有效的方式创建结构光图案，以从紧凑的准直光源获得足够的照明。人工眼睑已被确定为一个很好的解决方案，这一要求。这两种技术的整合在概念上是可行的，并将提供最有效的生物工程方法，以实现外科医生日常腹腔镜和内窥镜手术所需的视觉成像方式。
