The paper presents the design improvement of a medical instrument used for a robotic-assisted radiofrequency ablation (RFA). In the first part, the requirements of the device have been pointed out, and then, the prototype of the device has been analyzed and its weaknesses have been identified. Some finite element simulations have been achieved to test the mechanical strength of the device in various conditions. Based on the derived numerical data, the study shows the specific optimization parameters for the device, which can be improved without changing its general structure
