Development and evaluation of a new microwave electrode marked the scale and figures for deep-seated hepatocellular carcinoma

Abstract

As an aid in more accurate determination of the location of the tip of a microwave electrode for deep site coagulation in the laparoscopic local ablation treatment of liver cancer, we added figures indicating the distance from the tip to the side of the scale. This slight improvement facilitated the evaluation of the insertion length of the electrode from the liver surface. This improved type electrode may be also useful for percutaneous treatment.
