In this paper, we designed, built, and tested a novel single-port access laparoscopic surgery (SPA) specific camera system. This device (magnet camera) integrates a light source and video camera into a small, inexpensive, portable package that does not compete for space with the surgical tools during SPA. The device is inserted through a 26-mm incision in the umbilicus, followed by the SPA port, which is used to maintain an insufflation seal and support the insertion of additional tools. The camera, now in vivo, remains separate from the SPA port, thereby removing the need for a dedicated laparoscope, and, thus, allowing for an overall reduction in SPA port size or the use of a third tool through the insertion port regularly reserved for the traditional laparoscope. The SPA camera is mounted to the abdominal ceiling using one of the two methods: fixation to the SPA port through the use of a rigid ring and cantilever bar, or by an external magnetic handle. The purpose of the magnet camera system is to improve SPA by: 1) eliminating the laparoscope SPA channel; 2) increasing the field of view through enhanced camera system mobility; and 3) reducing interference between the camera system and the surgical tools at the port, both in vivo and ex vivo.
在本文中，我们设计、构建并测试了一种新型的单端口腹腔镜手术（SPA）专用摄像系统。该设备（磁控相机）将光源和摄像头集成到一个小巧、廉价、便携的套件中，在 SPA 过程中不会与手术工具争夺空间。该设备通过脐部的 26mm 切口插入，然后是 SPA 端口，用于维持充气密封并支持插入其他工具。现在，相机在体内，与 SPA 端口分开，从而无需专用腹腔镜，因此可以减小 SPA 端口的整体尺寸，或者通过常规保留用于传统腹腔镜的插入端口插入第三个工具。SPA 相机通过以下两种方法之一安装到腹部天花板上：通过使用刚性环和悬臂梁固定到 SPA 端口，或通过外部磁性手柄固定。磁控相机系统的目的是通过以下方式改善 SPA：1）消除腹腔镜 SPA 通道；2）通过增强相机系统的移动性来增加视野；3）减少体内和体外端口处相机系统与手术工具之间的干扰。
