  • High-speed Needle Shooting Device by an Electromagnetic Accelerator

抄録

<p>This paper presents a needle shooting device at high-speed for the puncture treatment. Problems of the puncture treatment are a curving of needles and a moving of organs because doctors puncture a needle at low speed. We assumed that puncturing a needle at high-speed can solve these problems. The needle with thread is used for inserting treatment instruments into the body. Coil-gun and Railgun were used for the small needle acceleration. We measured relations between the voltage and the velocity on Coil-gun and Railgun. In the case of Coil-gun, the velocity do not monotonous increases as the value of voltage increases. In the case of Railgun, the velocity monotonous increase as the value of voltage increases. The experimental results show that a needle with thread can be accelerated by Coil-gun and Railgun.</p>
