手术视野的全局内窥镜视图可以帮助避免并发症，如闭塞器官穿孔，并可以减少内窥镜的移位，以及使用传统内窥镜系统进行腹腔镜手术的通常时间。通过增加传统内窥镜的视场，开发了一种增强腹腔镜系统。该系统在体外实验台上进行了实现和测试。将高清微型摄像机集成到传统的内窥镜中，获得腹腔大视场的全景视觉装置。额外的摄像头安装在内窥镜体周围，作为一副眼镜，提供了腹腔的全局视图，完成了传统的内窥镜视图。每个摄像头的帧率可以达到30张/秒，分辨率为1600 1200像素。为了能够将摄像头固定在内窥镜上，我们设计了一套通过套管针的部署、固定和快速提取系统，并在临床前实验（试验台和人体尸体）中进行了验证。临床前实验比较了单独使用传统内窥镜和单独使用该系统执行拾取任务所需的时间。统计上显著减少的程序时间被发现使用增强视频内窥镜系统的拾取和放置任务。与传统的内窥镜相比，增强视野的腹腔镜系统是可行的，并且具有优势。应该对该系统进行体内测试，以确定这一创新的临床应用。
A global endoscopic view of the surgical field could help avoid complications such as perforation of occluded organs and may reduce the endoscope displacements and also the usual time of laparoscopic procedure using a conventional endoscopy system. An augmented laparoscopy system was developed by increasing the field of view of a traditional endoscope. This system was implemented and tested in vitro using a testbench.High-definition miniature cameras were integrated into a traditional endoscope to obtain a panoramic vision device with a large field of view of the abdominal cavity. The additional cameras are mounted around the endoscopy body as a pair of glasses providing a global view of the abdominal cavity completing the traditional endoscopic view. Each camera can reach a frame rate of 30 images/second with a resolution of 1,600 1,200 pixels. To be able to fix the cameras to the endoscope, a deployment, fixation and rapid extraction system of the proposed device through the trocar was designed and validated in preclinical experiments (testbench and human cadaver). The preclinical experiments compared the time required to perform a pick-and-place task with the traditional endoscope alone and with the proposed system alone.A statistically significant reduction in procedure time was found using an augmented video endoscopy system for a pick-and-place task.An augmented laparoscopy system with increased field of view is feasible and may be advantageous compared with a traditional endoscope. In vivo testing of the system should be done to establish the clinical utility of this innovation.
