Needle Guiding Robot for Radiofrequency Ablation: Safety and Efficacy Study on Hepatocellular Carcinoma Patients — NGR  

Carcinoma, Hepatocellular Clinical Trial

Official title: Single Center and Exploratory Investigator-initiated Trial to Evaluate the Safety and Efficacy of Needle Guiding Robot System for Radiofrequency Ablation in Hepatocellular Carcinoma Patients

Status Recruiting

Clinical Trial Summary

The needle guiding robot helps targeting of radiofrequency ablation needles by matching computed tomography images and patients' bodies. Actual insertion of needles will be performed by doctors. This study evaluates the safety and efficacy of needle targeting on patients with hepatocellular carcinoma.

Clinical Trial Description

A robotic system has been developed that includes a needle-path planning system and a needle-guiding robot arm with computed tomography (CT) guidance. The robot consists of robot base, 5-axis robot arm with guiding end-effector and path-planner. Optical tracking system with a custom-designed registration jig is used for the spatial registration and validation. Advantages of the robotic system would be accurate targeting with diverse angulation of the robot arm in CT-guided tumor ablation. Furthermore, robotic intervention might potentially decrease procedure time and radiation exposure to patients. The purpose of this clinical trial with patients with hepatocelluar carcinoma is to assess the safety and efficacy of our CT-guided needle-guiding robot. ;
