DESCRIPTION (provided by applicant): Since its earliest developments over 25 years ago, minimally-invasive laparoscopic surgery has eliminated the long gashes of traditional surgery. The development of laparoscopic procedures, and the refinement of instrumentation, has made laparoscopic surgery less invasive, resulting in laparoendoscopic single-site surgery (LESS), common in urology. The LESS technique, along with the growing capabilities of therapeutic flexible endoscopy in treating gastrointestinal conditions, has increased the desire for even less invasive alternatives, such as natural orifice transluminal endoscopic surgery (NOTES), which has been demonstrated in animal models via transvaginal, transgastric, transrectal, and transvesical approaches. A successful LESS and NOTES technique, however, requires superior instrumentation that will be manipulated in confined space and does not interfere with each other. Intelligent Optical Systems (IOS) proposes the development of a Surgical Instrument Guide - MEMS (SIG-MEMS) for emerging LESS and NOTES applications. The proposed device will be used for tracking a surgical instrument within a human body, via noncontact, passive, optical range finding. It will provide information on distances between an organ and an approaching instrument tip, and will feed this information back to the surgeon. The proposed SIG-MEMS will optically produce two spatially separated images to perform a triangulation calculation, but will use only one imaging channel -- unlike conventional stereo-devices, which use two channels. Because of its small dimensions and light weight, the sensor can be incorporated into a surgical tool, or can be a stand-alone part of the system, providing visual feedback and instrument tracking capabilities. In Phase I, Intelligent Optical Systems will demonstrate the tabletop prototype, and in Phase II will develop a detachable SIG-MEMS prototype that can be incorporated into surgical tools. PUBLIC HEALTH RELEVANCE: The major application of the SIG-MEMS will be for use in the new emerging procedures of minimally invasive surgery such as LESS and NOTES. It will warn the surgeon when the instrument is approaching a vital part of the tissue, and will simultaneously provide important instrument positioning information in relation to other instruments.

描述（由申请人提供）：自 25 年前最早发展以来，微创腹腔镜手术已经消除了传统手术的长切口。腹腔镜手术的发展和器械的完善，使得腹腔镜手术的侵入性较小，从而产生了泌尿外科常见的腹腔镜单部位手术（LESS）。 LESS 技术以及柔性内窥镜治疗胃肠道疾病的能力不断增强，增加了对侵入性更小的替代方案的需求，例如自然孔腔内窥镜手术 (NOTES)，这已通过经阴道、经胃的动物模型得到证实。 、经直肠和经膀胱入路。然而，成功的 LESS 和 NOTES 技术需要能够在有限空间内操作且互不干扰的高级仪器。智能光学系统 (IOS) 提议为新兴的 LESS 和 NOTES 应用开发手术器械指南 - MEMS (SIG-MEMS)。所提出的设备将用于通过非接触式、被动式光学测距来跟踪人体内的手术器械。它将提供器官和接近的器械尖端之间的距离信息，并将这些信息反馈给外科医生。所提出的 SIG-MEMS 将以光学方式产生两个空间分离的图像以执行三角测量计算，但仅使用一个成像通道 - 与使用两个通道的传统立体设备不同。由于尺寸小、重量轻，该传感器可以集成到手术工具中，也可以作为系统的独立部分，提供视觉反馈和器械跟踪功能。在第一阶段，智能光学系统将展示桌面原型，在第二阶段将开发可拆卸的 SIG-MEMS 原型，该原型可以集成到手术工具中。 公共健康相关性：SIG-MEMS 的主要应用将用于新兴的微创手术，例如 LESS 和 Notes。当器械接近组织的重要部分时，它会向外科医生发出警告，并同时提供与其他器械相关的重要器械定位信息。
