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年前的最早发展以来，最低侵入性的腹腔镜手术消除了长期的传统手术灾难。腹腔镜程序的发展和仪器的完善，使腹腔镜手术降低了侵入性，导致腹腔镜检查单位手术（少），在泌尿外科中常见。较少的技术以及治疗性内窥镜在治疗胃肠道疾病中的越来越多的能力增加了人们对较少侵入性替代方案的渴望，例如天然孔液压式内窥镜外科手术（NOTES），这些手术已通过动物模型在动物模型中通过经varagical，传染性，传播性，转直肠和转移方法证明。然而，成功的较少并注意到技术需要在密闭空间中操纵的卓越仪器，并且不会彼此干扰。智能光学系统（IOS）提议开发手术仪器指南 - MEMS（SIG -MEMS），以减少出现和注释应用。该提出的设备将用于通过非接触，被动，光学范围查找来跟踪人体内的手术仪器。它将提供有关器官和接近仪器尖端之间距离的信息，并将此信息交给外科医生。所提出的SIG-MEM将光学地产生两个空间分离的图像来执行三角测量计算，但仅使用一个成像通道 - 与常规立体声驱动器不同，它使用两个通道。由于其尺寸较小和重量轻，因此可以将传感器合并到外科手术工具中，也可以成为系统的独立组成部分，从而提供视觉反馈和仪器跟踪功能。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，该原型可以纳入外科工具。 公共卫生相关性：SIG-MEMS的主要应用将用于新的新兴手术，例如Simest和Notes。当该仪器接近组织的重要部分时，它将警告外科医生，并同时提供与其他仪器有关的重要仪器定位信息。
