Abstract

Abstract Background: Minimally invasive surgeries rely on laparoscopic camera views to guide the procedure. Traditionally, an expert surgical assistant operates laparoscopic camera. This process is distracting, and the camera is not always placed in an ideal location. To mitigate these problems, we have developed a laparoscopic automatic navigation method. Methods: In this article, a way to determining surgery status based on the distance of surgical instruments is presented. Combining with the surgery status, the region of interest (ROI) in laparoscopic image is defined, and related parameters are given in detail. Comprehensive the above content, the method of laparoscopic automatic navigation based on the ROI is proposed. Results: Finally, introducing the method into a kind of typical minimally invasive laparoscopic surgery robot system (MLSRS), and the method is simulated by using some typical surgical tasks. Conclusion: The results show that this method is feasible.

机器人辅助腹腔镜手术中基于感兴趣区域的腹腔镜自动引导

背景:微创手术依赖于腹腔镜下的摄像机视图来指导手术。传统上，专家外科助理操作腹腔镜相机。这个过程是分散注意力的，而且相机并不总是放在一个理想的位置。为了减轻这些问题，我们开发了一种腹腔镜自动导航方法。方法:提出一种基于手术器械距离判断手术状态的方法。结合手术状态，定义了腹腔镜图像中的感兴趣区域(ROI)，并给出了相关参数。综合上述内容，提出了基于ROI的腹腔镜自动导航方法。结果:最后，将该方法引入到一种典型的微创腹腔镜手术机器人系统(MLSRS)中，并通过一些典型的手术任务对该方法进行了仿真。结论:该方法是可行的。

期刊介绍： omputer Assisted Surgery aims to improve patient care by advancing the utilization of computers during treatment; to evaluate the benefits and risks associated with the integration of advanced digital technologies into surgical practice; to disseminate clinical and basic research relevant to stereotactic surgery, minimal access surgery, endoscopy, and surgical robotics; to encourage interdisciplinary collaboration between engineers and physicians in developing new concepts and applications; to educate clinicians about the principles and techniques of computer assisted surgery and therapeutics; and to serve the international scientific community as a medium for the transfer of new information relating to theory, research, and practice in biomedical imaging and the surgical specialties. The scope of Computer Assisted Surgery encompasses all fields within surgery, as well as biomedical imaging and instrumentation, and digital technology employed as an adjunct to imaging in diagnosis, therapeutics, and surgery. Topics featured include frameless as well as conventional stereotactic procedures, surgery guided by intraoperative ultrasound or magnetic resonance imaging, image guided focused irradiation, robotic surgery, and any therapeutic interventions performed with the use of digital imaging technology.
