抽象的。同轴投射成像(CPI)模块从手术的本地部位获取手术场景图像，将其无线传输到远程部位，并将指导性注释投射到外科领域。在远程站点，显示手术场景图像，并且将来自外科专家的指导性注释无线传输回本地站点，以便指导经验较少的外科医生进行手术干预。CPI模块通过将成像臂与投影臂耦合的同轴光路设计以及通过恢复手术场景的真实颜色的色彩校正算法，实现了手术野的无缝成像和指导性注释的准确投影。我们的远程引导介入的台式研究证实，所提出的系统在工作距离从300到500 mm的范围内具有优于1 mm的定位精度。我们在兔模型上进行的环甲切开术的活体研究证明了远程指导手术导航的概念。这是基于CPI的远程引导手术的第一例报告。建议的技术可以潜在地用于外科培训和在资源有限的情况下进行远程手术。
Abstract. A coaxial projective imaging (CPI) module acquires surgical scene images from the local site of surgery, transfers them wirelessly to the remote site, and projects instructive annotations to the surgical field. At the remote site, the surgical scene images are displayed, and the instructive annotations from a surgical specialist are wirelessly transferred back to the local site in order to guide the surgical intervention by a less experienced surgeon. The CPI module achieves seamless imaging of the surgical field and accurate projection of the instructive annotations, by a coaxial optical path design that couples the imaging arm with the projection arm and by a color correction algorithm that recovers the true color of the surgical scene. Our benchtop study of tele-guided intervention verifies that the proposed system has a positional accuracy of better than 1 mm at a working distance ranging from 300 to 500 mm. Our in vivo study of cricothyrotomy in a rabbit model proves the concept of tele-mentored surgical navigation. This is the first report of tele-guided surgery based on CPI. The proposed technique can be potentially used for surgical training and for telementored surgery in resource-limited settings.
