The extracorporeal pneumoperitoneum access bubble (EPAB) creates a transparent extension of the pneumoperitoneum and has been developed to facilitate large organ extraction and tissue approximation in patients undergoing endoscopic surgical procedures. When fully deployed, the EPAB excludes the abdominal parietes from the emergent organ and dilates the exit wound by an average of 48.5%, irrespective of its location. It thus eliminates the problems of contamination and tumor seedling implantation during the removal of resected organs, aside from expediting the extraction. The operating version of the EPAB enables the introduction of the surgeon's or assistant's hands or instruments into the bubble and thence into the peritoneal cavity without deflation of the pneumoperitoneum. By this means, it reduces the technical difficulties required to dissect organs and achieve reconstruction by hand suturing or stapling.
体外气腹接入泡（EPAB）可形成气腹的透明延伸部分，其研发目的是便于接受内镜手术的患者进行大型器官提取和组织对合。完全展开时，EPAB可使腹壁与取出的器官分离，并使出口创口平均扩张48.5%，无论创口位于何处。因此，除了加快提取速度外，它还消除了切除器官取出过程中的污染和肿瘤种植问题。EPAB的手术版本可让外科医生或助手的手或器械进入泡内，进而进入腹腔，而无需放气腹。通过这种方式，它降低了手工解剖器官以及通过手工缝合或吻合器进行重建所需的技术难度。
