Polyurethane foam (PU foam) is a new material which is being used in producing both macro-anatomical and micro-anatomical specimens. PU foam is simple to use, without need for special equipment. The present study was carried out to evaluate morphology of coronary sinus and its tributaries. During the study, we encountered few problems in carrying out injections. Coronary sinus and its tributaries were difficult to cannulate since the coronary sinus lacks a vascular stem, around which ligature can be tied before injection so that the cannula can be held in place. In contrast, in majority of the organs it is easy to inject since they possess tubular vascular stem to hold the cannula in place. A new device was developed which could be used to cannulate coronary sinus orifice to inject the casting media. The second problem we faced was saponification of adipose tissue. This made corrosion of the soft tissue difficult. Hence in this study, we describe the device we have developed to place in the coronary sinus orifice, and how saponified adipose tissue was taken care during the actual maceration step.
聚氨酯泡沫（PU泡沫）是一种用于制作大体解剖标本和显微解剖标本的新型材料。PU泡沫使用简便，无需特殊设备。本研究旨在评估冠状窦及其属支的形态。在研究过程中，我们在进行注射时遇到了一些问题。冠状窦及其属支难以插管，因为冠状窦缺乏血管干，在注射前无法在其周围结扎以固定插管。相比之下，大多数器官易于注射，因为它们有管状血管干来固定插管。我们开发了一种新装置，可用于插入冠状窦口以注射铸型介质。我们面临的第二个问题是脂肪组织的皂化。这使得软组织的腐蚀变得困难。因此，在本研究中，我们描述了我们开发的用于放置在冠状窦口的装置，以及在实际浸软步骤中如何处理皂化的脂肪组织。
