オフポンプ冠動脈バイパス術のための接触時に開くバルブをもつスタビライザによる振動低減効果

抄録

The stabilizer is used for Off-pump coronary artery bypass grafting. This surgical instrument has the rubber suckers, variable stiffness arm and fixed part. When one of suckers has been peeled off, the adhesion force of stabilizer was decreased, because the suckers was connected by stainless tube. We proposed the stabilizer with valves opened when the sucker is contacted on the heart. Previous study has shown that rubber type stabilizer was fabricated. In this paper, we show the vibration reduction effect of the stabilizer with valves using the cardiac pulsation type coronary anastomosis training system. When the fabricated stabilizer, the reduction ratio of displacement was 0.19. On the other hand, the ratio was 0.13 when the surgical instrument.
