EasyVis: laparoscopic surgical visualization through an untethered, panoramic, three-dimensional imaging system

 产品说明： 腹腔镜手术越来越普遍，并形成微创方法的基础，为患者提供了许多临床益处。腹腔镜手术期间的可视化的当前范例围绕单个摄像机的使用，该单个摄像机插入到少数腹腔镜端口中的一个中并由摄像机操作员操纵。不幸的是，这种可视化范例在可视化质量和操作效率方面具有许多众所周知的缺点。它缺乏将拉格视场和三维（3D）视觉完全集成的能力。它占用一个手术端口，专门用于观察而不是仪器，需要专门的操作员来不断操纵摄像机，由于仪器的污迹、雾化和飞溅以及干扰和闭塞，易于模糊可视化，并且被麻烦地拴系。 我们的目标是解决目前腹腔镜可视化相关的所有这些缺陷。我们将开发一个范式转变，集成，不受约束，全景，三维腹腔镜可视化系统，称为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，从任意视点和角度提供不间断的腹腔内全景视图，并对任何特定部位进行近距离3D可视化，所有这些都在手术外科医生的直接、免提、轻松和完全控制下，完全无需摄像机导航。EasyVis不占用任何额外的手术端口，并解决了与污迹、雾化和飞溅以及器械干扰和闭塞相关的问题。此外，EasyVis无线通信，因此没有悬垂的电线。EasyVis为外科医生提供了更高质量的增强可视化，易于控制，手术过程中中断最少。 三个具体目标将被追求，包括可调焦距的微型相机和集成的套管针相机组件，实时全景拼接和3D可视化，以及一个集成的，完整的EasyVis原型的发展。在这些目标的每个阶段，将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，利用完成任务的时间的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。

 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.
