通过切除和缝合梗塞区域，可以减少由于心肌梗塞和扩张型心肌病而导致的扩张的心室容积。每个患者心脏的手术计划都是在手术室确定的。使用心肺机，容量减少测试可估计适合跳动和增厚的心室容量。心脏外科医生触诊心肌，以确定应切除的心肌区域，然后切除并缝合心室。手术中了解这些手术过程的机会有限，即使术前使用最新的医学测量技术MRI、XCT和回声也无法宣布患病心肌的状况。因此，心脏外科医生非常需要一种能够产生减容手术手术过程训练机会的系统。我们开发了由虚拟心脏和触觉装置组成的心肌触诊训练系统，受到了心脏外科医生的赞赏。本文介绍了我们开发的训练系统，以及对虚拟心脏的一些改进，使其更加实用。
Dilated ventricular volumes due to myocardial infarction and dilated cardiomyopathy are reduced by excising and sewing up the infarction regions. The surgical plans for each patients' heart are determined in the operating room. Using a heart-lung machine, a volume reduction test estimates the suited ventricular volume for beating and thickening. The cardiac surgeons palpate a cardiac muscle in order for identifying the cardiac muscular regions that should be excised, and resects and stitches up the ventricle. Opportunities to learn these surgical processes are limited in the operation, and the conditions of the diseased cardiac muscle can not be declared even if the latest medical measuring techniques, MRI, XCT, and echo are used before the surgery. The cardiac surgeons, therefore, highly desire a system which can produce the training opportunity of the surgical process of the volume reduction surgery. We have developed a training system for cardiac muscle palpation which is composed of a virtual heart and a haptic device, and they were appreciated from the cardiac surgeons. This paper introduces the training system we have developed, and some improvements of the virtual heart to make more practical.
