Establishment of totally endoscopic cardiac surgery using ZEUS surgical system

使用Computer Motion公司生产的Zeus外科系统，在大阪大学进行了外科手术技术的动物训练。之后，我们将该系统应用于人体冠状动脉搭桥术中的胸廓内动脉采集。我们发现了系统手臂定位的困难。在问题解决后，针对难度较大的房间隔缺损封堵术，引入了该系统。这项手术需要体外循环。我们改进了右心房切开的进港系统。我们用Zeus手术系统成功地完成了8例房间隔缺损封堵术。无输血，7例术后出院。ZEUS手术系统是一种非常有用的微创心脏手术系统。

The animal training of surgical techniques using ZEUS surgical system, which is produced by Computer Motion, was carried out in Osaka University. After that, we introduced this system for harvesting the internal thoracic artery in the human operation of coronary artery bypass grafting. We have found the difficulty of the positioning of the arms of the system. After the resolving the problem, we introduced this system for the more difficult operation, the closure of the atrial septal defect. This operation required extra-corporeal circulation. We improved the Port-Access system for the incision of right atrium. We performed the the closure of atrial septal defect using ZEUS surgical system in 8 patients successfully. They required no blood transfusion, and discharged in 7 clays after the operation.ZEUS surgical system is very useful system for less invasive cardiac surgery.
