According to statistics on the global market development trend of surgical robots, the current economic scale of surgical robots will increase to 13 billion U.S. dollars, showing its high development potential. On the other hand, according to a report from the World Health Organization (WHO), liver cancer is the second deadliest cancer in the world. How to preserve more livers during surgery to maintain life is a clinically important issue currently. At present, thermal ablation is one of the most suitable treatment methods for patients with tumors smaller than 2 cm or with multiple tumors. However, during the treatment, it is necessary to rely on preoperative analysis of Computed Tomography (CT), intraoperative machine vision and real-time ultrasound image analysis to assist the doctors in puncturing the correct position of liver tumor and performing thermal ablation. This surgical method is suitable for using navigation of robotic-assisted system to assist spatial positioning, and the system can also perform real-time ultrasound image analysis and information feedback of thermal ablation. In addition to an introduction to the navigation of robotic-assisted system, this article also takes the dual-arm robotic-assisted system of liver cancer thermal ablation as an example to introduce the required spatial positioning technology of machine vision, interactive robotic arm control and ultrasonic image feedback, etc., and will conduct a phantom experiment to show its results. |
