In coronary artery bypass grafting (CABG), surgeons use a stabilizer to suppress the heart surface excursion locally. However, it was reported that there is a significant residual motion on the operation area of the heart surface that is larger than the required accuracy for suturing. Therefore we developed a new cardiac active stabilizer intended to reduce this residual motion. Our system consists of a voice coil motor, a laser displacement sensor, an acceleration sensor, and a computer. The voice coil motor is driven by feedbacking the residual motion which is measured by the laser displacement sensor. After convergence of the residual motion, the laser displacement sensor is taken off from the operative field and the voice coil motor keeps driving using the recorded output waveform and a timing which is measured by the acceleration sensor. We performed both a phantom experiment and an animal experiment. As a result of the phantom experiment, we confirmed that our device enables to reduce the residual motion to 20 %. In the animal experiment, the residual motion was reduced to 50 %.
