左室形成術のための心筋触診訓練システムの開発

抄録

For the left ventricular plastic surgery, cardiac muscle palpation is the only method of determining the regions that should be removed. Because the left ventricle would be operated after the chest incision with using a heart-lung machine, the opportunity to palpate the diseased cardiac muscle is limited in the operative theater. The training system for cardiac muscle palpation we have developed is composed of a beating virtual heart and a 5-DOF haptic device, which is effective to overcome the present condition that the surgical training opportunities are poor. Experimental results of this study show that the justification of the virtual heart modeling comparing with a living dog heart and the real-time correlation between the virtual heart and the haptic device.The validation with a skillful surgeon is needed to make our system more practical.
