The manipulation of the surgical field in laparoscopic surgery, through small incisions with rigid instruments, reduces free sight, dexterity, and tactile feedback. To help overcome some of these drawbacks, we present a prototype research and development platform, CustusX, for navigation in minimally invasive therapy. The system can also be used for planning and follow-up studies. With this platform we can import and display a range of medical images, also real-time data such as ultrasound and X-ray, during surgery. Tracked surgical tools, such as pointers, video laparoscopes, graspers, and various probes, allow surgeons to interactively control the display of medical images during the procedure. This paper introduces navigation technologies and methods for laparoscopic therapy, and presents our software and hardware research platform. Furthermore, we illustrate the use of the system with examples from two pilots performed during laparoscopic therapy. We also present new developments that are currently being integrated into the system for future use in the operating room. Our initial results from pilot studies using this technology with preoperative images and guidance in the retroperitoneum during laparoscopy are promising. Finally, we shortly describe an ongoing multicenter study using this surgical navigation system platform.
在腹腔镜手术中，通过小切口使用刚性器械对手术视野进行操作，会降低视野自由度、灵活性和触觉反馈。为了帮助克服其中一些缺点，我们展示了一个用于微创治疗导航的原型研发平台CustusX。该系统还可用于规划和随访研究。借助这个平台，我们能够在手术期间导入并显示一系列医学图像，以及诸如超声和X射线等实时数据。被跟踪的手术工具，如指针、视频腹腔镜、抓钳和各种探头，使外科医生能够在手术过程中交互式地控制医学图像的显示。本文介绍了腹腔镜治疗的导航技术和方法，并展示了我们的软件和硬件研究平台。此外，我们通过腹腔镜治疗期间进行的两项试点研究的实例来说明该系统的使用情况。我们还介绍了目前正在集成到系统中的新进展，以便未来在手术室使用。我们使用该技术结合术前图像并在腹腔镜手术期间对腹膜后进行引导的初步试点研究结果很有前景。最后，我们简要描述了一项正在进行的使用该手术导航系统平台的多中心研究。
