。[Scope of Claim for Utility Model Registration] (1) A tip for a surgical device that transmits ultrasonic vibration energy and is tubular in shape and has an end surface inserted into an affected area that is oblique to the axial direction of the tube. A chip structure for a surgical device using ultrasonic vibration energy, characterized in that a protrusion projecting in the insertion direction is formed at an arbitrary position other than the insertion tip of the end face. (2) The end face has two slopes with different inclinations, the slope including the insertion tip and the slope forming the protrusion, and the angle between the slope including the tip and the axis of the tube forms the protrusion. Claim 1 characterized in that the angle formed between the slope and the axis of the pipe is smaller than the angle formed by the slope and the axis of the pipe.
A chip structure of a surgical device using the described ultrasonic vibration energy. (3) The end surface is formed into a curved shape, and the angle between the end surface at the tip and the axis of the tube is smaller than the angle between the end surface and the axis of the tube at the location where the protrusion is formed. The chip structure of a surgical device using ultrasonic vibration energy according to claim 1.
