制作肺段分色标本的方法:1、肺脏应尽量新鲜,最好不超过24小时(经甲醛溶液固定的肺,因血液凝结,无弹性,不能应用).可采用新生儿尸体的肺脏制作,不但易得,而且能制作较好的肺段分色标本,当注入色胶液后体积可膨大2~3倍.2、摘取肺脏时要细心操作,勿伤及胸膜脏层,否则注射时会造成胶液外漏,不能获得满意的标本.取出肺脏时无需冲洗,为防止干燥,可浸入2%石碳酸水溶液中待用.3、注射胶液前,在肺门处用钝解剖法清理叶支气管到段支气管始端,再用探针找准每个段支气管再进行注射.右肺一般容易找到十个肺段支气管的开口,而在左肺上叶的尖段和后段,开始为一个肺段支气管,下叶的内前底段和前底段开始时也常为一个肺段支气管,故左肺只能找到八个肺段支气管的开口.4、配制胶液用明显胶和水,其比例为1:2,并隔水加温溶化.色料应选用鲜艳的红、黄、兰、白、绿等各种广告色,分别加入热胶液中,搅拌均匀,并置温水中以防凝固.不可用水溶性颜料.5、注射前先向段支气管注入少量空气,观察该肺段所占据的范围来决定注射的色胶液,随即将空气挤出,再进行注射. 应当注意的是相邻的肺段不能注入相似的色胶液,以免混淆不清.6、注射用的玻璃插管应与段支气管口的大小相近.如插
Methods for making segmental specimens of lung segments: 1. The lungs should be fresh, preferably not more than 24 hours (fixed by formaldehyde solution of the lung due to blood coagulation, inelastic, can not be applied.) The lungs can be used neonatal carcass production, Not only easy to get, but also can produce better color segmentation of the lung segment, when injected into the color of the glue volume can be expanded 2 to 3 times .2, the removal of the lungs should be careful operation, do not hurt the pleural visceral, or injection Will result in glue leakage, can not get satisfactory specimens .No need to wash out the lungs, in order to prevent drying, can be immersed in 2% carbolic acid solution to be used .3, before the injection of glue, hilar dissection with blunt dissection Leaf bronchus to the beginning of the segment of the bronchus, and then pin the probe to identify each segment of the bronchus and then injected right lung is generally easy to find the ten lung segment bronchial openings, and in the left upper lobe of the sharp segment and the back segment, Pulmonary bronchus, the lower anterior leaf segment and the anterior segment of the anterior segment is also often a bronchus, so the left lung can only find eight bronchial lung segment opening .4, the preparation of glue with significant glue and water, The ratio of 1: 2, and water warm melt. Color should be used bright red, yellow, blue, White, green and other advertising colors, were added hot glue, stir, and set in warm water to prevent coagulation.Unable water-soluble pigments .5, before injection of a small amount of air into the segment of the bronchus to observe the occupancy of the lung segment Of the range to determine the injection of color glue, then the air extrusion, and then injection.It should be noted that the adjacent lung segments can not be injected into a similar color of glue, so as not to confuse .6, injection of glass cannula Should be similar to the size of the segment bronchial mouth
