Radio knife is a common tool in surgery. However it has a severe issue that it strongly adheres to the human body frequently through the coagulation of blood and/or human tissues. In order to overcome this issue, we developed the new tip for the radio knife that have many micro grooves on the tip and the grooves were filled with several kinds of materials. It was conducted that the new tip was evaluated in the adhesion test between the tips and porcine liver. As a result, adhesion force for the patterned tip which was filled with several kinds of material decreased to 8% comparing to normal tip. Consecutive cutting time increased to 5 times comparing to the normal tip.
