Abstract

PROBLEM TO BE SOLVED: To stop bleeding and solidify it at once over a wide area by surrounding a part of bundle of plural slender pins composed of conductive materials in lengthwise direction with a cylinder and widening the top ends of parts of pins protruded from the cylinder distributedly over the area wider than the cross-sectional area of the cylinder. SOLUTION: A scalpel tip electrode has plural slender stick-shaped pins 20 composed of conductors and a cylinder 22 for bundling and fixing one end of these members, and the other ends of pins 20 are formed while being radially spread. Besides, one ends of pins 20 are spread on a plane 24 distributed on one or plural circles or the center of the circle (a). Otherwise, one ends of pins 20 are spread on a curved surface 26 and distributed on one or plural circles or the center of the circle (b). These pins 20 or the cylinder 22 are composed of a conductive metal, and the pins 20 and the cylinder 22 are fixed by brazing one end 22a of the cylinder 22a. Besides, it is preferable to set the diameter of the pin 20 from 0.2mm to 0.3mm and to set the number of pins 20 from 2 to 50.
