项目摘要
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,构成了微创方法的基础,为患者带来了许多临床益处。腹腔镜手术期间可视化的当前可视化范式围绕使用单个相机的使用插入,该相机插入了少数腹腔镜端口之一,并由相机操作员操纵。不幸的是,这种可视化范式在可视化质量和操作效率方面具有许多众所周知的缺点。它缺乏完全整合lage视野和三维(3D)视野的能力。它占据一个外科端口,专门用于观看而不是仪器,需要一个专用的操作员来持续操作相机,由于污迹,雾气,溅起和干扰以及仪器的闭合,并且被cunbersomely绑扎。我们的目标是解决与之相关的所有这些缺陷,我们将开发一种范式转移,整合,不受束缚,全景,3D腹腔镜可视化系统(称为EasyVis),以显着提高腹腔镜手术的效率。 EasyVis将以毫米尺度的多个微型乳胶与手术端口整合在一起,以从任何任意的观看点和角度从任何特定位置的任何特定位置,无需直接,无权的,轻松,轻松且充分控制手术外科,完全消除了相机导航的需求。 Easyvis不会占据任何额外的手术端口,并解决了与污渍,雾气和溅起以及干扰以及仪器闭塞相关的问题。此外,EasyVis无线通信,因此消除了悬空的绳索。借助Easyvis,外科医生可以增强可视化,并在手术过程中具有更高质量,易于控制和最小的中断。将追求三个特定的目标,包括开发可调的焦点微型胶体和集成的套管照相机组件,实时全景缝制和3D可视化,以及集成的,完整的Easyvis原型。在这些目标的每个阶段,将使用时间的定量指标来完成任务的定量指标,并对技术技能的客观结构化评估进行了验证的评分系统,以验证Easyvis对腹腔镜手术的影响。
