目的利用胸腔镜或腹腔镜进行微创手术（MIS）正成为一种越来越普遍的外科技术。在MIS中，胸腔镜的放大视图可以帮助外科医生进行精确的手术。然而，存在可见区域变窄的风险。为了确认手术视野是安全的，外科医生会将胸腔镜拉回检查目标的边缘区域，并在MIS过程中多次插入。为了减轻外科医生的负担，我们的目标是使用一种新开发的称为“全景视觉环”（PVR）的设备来可视化整个胸腔。方法采用PVR代替伤口牵开器或套管针。它是一种环形插座，有一个大孔用于胸腔镜，四个小孔用于放置在大孔周围的微型摄像机。来自微型摄像机的图像融合成一个更宽的视图，可以看到整个胸腔。外科医生可以通过检查胸腔镜视野之外存在的东西来进行手术。此外，她/他可以从整个腔的图像检查是否发生出血。结果我们通过三维全尺寸胸椎模型评估了PVR的视野扩展能力。实验结果表明，在PVR生成的全景视图中可以看到整个胸腔。我们还演示了使用PVR在虚拟MIS中进行肺叶切除术。外科医生可以在检查整个腔的同时进行肺叶切除术。结论我们开发了PVR，它使用微型辅助摄像机在MIS过程中创建整个胸腔的全景视图。我们的目标是通过PVR的开发，使MIS对患者更安全，对外科医生更舒适。
PurposeMinimally invasive surgery (MIS) using a thoraco- or laparoscope is becoming a more common surgical technique. In MIS, a magnified view from a thoracoscope helps surgeons conduct precise operations. However, there is a risk of the visible area becoming narrow. To confirm that the operation field is safe, the surgeon will draw the thoracoscope back to check the marginal area of the target and insert it again many times during MIS. To reduce the surgeon’s load, we aim to visualize the entire thoracic cavity using a newly developed device called “panorama vision ring” (PVR).MethodThe PVR is used instead of a wound retractor or a trocar. It is a ring-type socket with one big hole for the thoracoscope and four small holes for tiny cameras placed around the big hole. The views from the tiny cameras are fused into one wider view that visualizes the entire thoracic cavity. A surgeon can proceed with an operation by checking what exists outside of the thoracoscopic view. Also, she/he can check whether or not bleeding has occurred from the image of the entire cavity.ResultsWe evaluated the view-expansion ability of the PVR by using a three-dimensional full-scale thoracic model. The experimental results showed that the entire thoracic cavity could be visible in a panoramic view generated by the PVR. We also demonstrated pulmonary lobectomy in virtual MIS using the PVR. Surgeons could perform a pulmonary lobectomy while checking the entire cavity.ConclusionWe developed the PVR, which uses tiny auxiliary cameras to create a panoramic view of the entire thoracic cavity during MIS. We aim to make MIS safer for patients and more comfortable for surgeons through the development of the PVR.
