Making a diameter of needle small is effective for reducing the pain of patients. However, thinning a needle leads to easy buckling in the puncturing process, because the aspect ratio of needle becomes high. When thin needle, it is effective to reduce the patient's pain. From acupuncture and mosquito needle behavior tips, we propose a mechanism to puncture the needle little by little. Furthermore, by enveloping the cylinder needle from directly above the skin, we propose a mechanism for preventing buckling. Therefore, by using a mechanical pencil system, and performs various studies and found a method capable without buckling puncture the thin needle
