 DESCRIPTION: Laparoscopic surgery is increasingly common and forms the basis of the minimally invasive approach, offering numerous clinical benefits to patients. The current paradigm in visualization during laparoscopic surgery revolves around the use of a single camera which is inserted into one of a few laparoscopic ports and manipulated by a camera operator. This paradigm of visualization unfortunately has many well-known drawbacks in terms of quality of visualization and efficiency in operation. It lacks the ability to fully integrate lage field of view and three-dimensional (3D) vision. It occupies one surgical port exclusively for viewing rather than instrumentation, requires a dedicated operator for constant maneuver of the camera, is prone to obscured visualization due to smudging, fogging and splatter and interference and occlusion from instruments, and is cumbersomely tethered. Our goal is to address all these deficiencies associated with current laparoscopic visualization. We will develop a paradigm-shift, integrated, untethered, panoramic, 3D laparoscopic visualization system, called EasyVis, for significantly improved efficiency for laparoscopic surgery. EasyVis directly integrates multiple microcameras at the millimeter scale with the surgical ports to provide uninterrupted intra-abdominal panoramic view from any arbitrary viewing point and angle, and close-up 3D visualization of any specific spot, all under direct, hands-free, easy and full control of the operating surgeon, completely eliminating the need of camera navigation. EasyVis does not occupy any extra surgical port, and solves the problems associated with smudging, fogging and splatter and interference and occlusion from instruments. Furthermore, EasyVis communicates wirelessly and hence does away the dangling cords. With EasyVis, the surgeon is provided with enhanced visualization with higher quality, easy control and minimum interruption during the operation. Three specific aims will be pursued, including development of tunable-focus microcameras and integrated trocar-camera assembly, real-time panorama stitching and 3D visualization, and an integrated, complete EasyVis prototype. At each phase of these aims, rigorous clinical testing and evaluation will be performed to validate the impact of EasyVis to laparoscopic surgery, utilizing quantitative metrics of time to complete tasks and the validated scoring system of Objective Structured Assessment of Technical Skill.

 描述：腹腔镜手术越来越普遍，形成了微创方法的基础，为患者提供了许多临床益处。目前腹腔镜手术中的可视化范例围绕使用插入几个腹腔镜端口之一的单个摄像机进行。不幸的是，这种可视化范例在可视化质量和操作效率方面存在许多众所周知的缺点，它缺乏完全集成大视野和三维 (3D) 的能力。它占用一个手术端口，专门用于观察而不是使用仪器，需要专门的操作员来不断操纵相机，容易因仪器的污迹、雾气和飞溅以及干扰和遮挡而导致可视化模糊，并且束缚起来很麻烦。我们的目标是解决与当前腹腔镜可视化相关的所有这些缺陷，我们将开发一种范式转变的、集成的、不受束缚的、全景的 3D 腹腔镜可视化系统。 EasyVis，显着提高腹腔镜手术的效率 EasyVis 直接将多个毫米级微型摄像机与手术端口集成，可从任意观察点和角度提供不间断的腹腔内全景，以及任何特定点的特写 3D 可视化。一切都在手术医生的直接、免提、轻松和完全控制下，完全消除了摄像机导航的需要，EasyVis不占用任何额外的手术端口，并解决了相关问题。此外，EasyVis 还可以进行无线通信，从而消除了悬空的电线，为外科医生提供了更高质量的增强可视化、易于控制和最小化手术过程中的干扰。将追求的目标包括开发可调焦微型相机和集成套管针相机组件、实时全景拼接和 3D 可视化，以及集成的、完整的 EasyVis在这些目标的每个阶段，将利用完成任务的时间定量指标和经过验证的技术技能客观结构化评估评分系统，进行严格的临床测试和评估，以验证 EasyVis 对腹腔镜手术的影响。
