Abstract

食管和胃癌病理分期模型教具，涉及有食管模型、胃模型及食管壁凹槽和胃壁凹槽，根据癌组织浸润食道壁和胃壁深度分期为早期癌和中晚期癌。早期癌为原位癌或粘膜下癌，但未侵及肌层。晚期癌为侵及粘膜下层以下深度（侵及肌层），甚至于穿过管壁侵犯临近组织。食管壁凹槽可替换早期食管癌模型和中晚期食管癌模型，胃壁凹槽可替换早期和中晚期胃癌模型。本发明整体结构简单，操作方便，教学直观，具有良好的教学演示效果。

Description

食管癌和胃癌病理分期模型教具
技术领域
本发明涉及一种医学教学用教具，尤其涉及食管癌、胃癌病理分期模型教具。
背景技术
在医学病理学教学中，食管癌和胃癌的分期是临床确定治疗方案和判断预后的重要依据，现有技术中的食管癌、胃癌教学用教具主要有教材插图、多媒体展示及大体标本观察，这些教具存在以下缺点。
发明内容
本发明内容：
为解决上述技术问题，本发明提供一种食管癌和胃癌病理分期模型教具，模拟实际的食管癌和胃癌病理分期的形态特点。
本发明通过以下技术方案实现的：一种食管癌和胃癌病理分期模型教具，包括食管模型和胃模型，食管模型下方与胃模型接通，食管模型和胃模型组织学结构包括粘膜层、粘膜下层、浅肌层和深肌层及外膜（或浆膜）层，食管模型和胃模型内面均设置有凹槽，活动插件可插入凹槽，所述活动插件包括早期食管癌模型、中晚期食管癌模型、早期胃癌模型和中晚期胃癌模型，早期食管癌模型包括原位癌模型和粘膜下癌模型；中晚期食管癌模型包括侵犯浅肌层、侵犯深肌层和侵犯食管临近组织；早期胃癌模型包括原位癌模型、粘膜下癌模型、侵犯浅肌层、侵犯深肌层和侵犯胃临近组织。
本发明的有益效果为：将消化道常见肿瘤食管癌和胃癌由早期癌发展为中晚期的病理过程，直观形象地展示给学生，便于学生理解记忆食管癌和胃癌病理分期，并可检验其学习效果，具有以下优点：
（1）结构合理、携带方便；
（2）直观形象、容易理解；
（3）可亲自操作病变分期模型的置换，用于教学效果的评价。
附图说明：
附图1是本发明所述食管和胃癌病理分期模型教具的结构示意图。
图中：
1、食管模型
2、胃模型
3、粘膜层
4、粘膜下层
5、浅肌层
6、深肌层
7、食管壁凹槽
8、胃壁凹槽
9、原位癌模型
10、粘膜下癌模型
11、侵犯浅肌层
12、侵犯深肌层
13、侵犯临近组织。
具体实施方式：
现参照图1，结合实施例证明如下：本发明所述的食管癌和胃癌病理分期模型教具，包括食管模型1和胃模型2，食管模型1下方与胃模型2接通，食管模型1和胃模型2组织学结构包括粘膜层3、粘膜下层4、浅肌层5和深肌层6及外膜（或浆膜）层，食管模型1和胃模型2内面均设置有凹槽7、8，活动插件可插入凹槽，所述活动插件包括早期癌模型和中晚期模型。食管癌活动插件包括早期食管癌模型：原位癌模型9、粘膜下癌模型10，中晚期食管癌模型包括侵犯浅肌层11、侵犯深肌层12和侵犯食管临近组织模型13。胃模型凹槽8可插接活动插件，包括早期胃癌模型：原位癌模型9、粘膜下癌模型10，中晚期胃癌：侵犯浅肌层模型11、侵犯深肌层12和侵犯胃临近组织13。
使用时，早期食管癌患者尚无明显症状，病变局限多为原位癌或粘膜下癌，此时将活动插件原位癌模型9和粘膜下癌模型10插接食管壁凹槽7内以模拟早期食管癌；中晚期食管癌为癌组织侵犯肌层，甚至于穿过食管壁外膜层而侵犯临近组织，此时将活动插件侵犯浅肌层模型11、侵犯深肌层模型12和侵犯临近组织模型13依次插接于食管癌凹槽7内，以模拟展示中晚期食管癌病理特点。
早期胃癌指癌组织仅限于粘膜层及粘膜下层，此时将活动插件原位癌模型9或粘膜下癌模型10插接胃模型凹槽8内，以模拟早期胃癌；中晚期胃癌指癌组织侵袭粘膜下层以下深度模型或侵犯深肌层，甚至于侵犯浆膜层面到达临近组织，此时将活动插件侵犯浅肌层模型11，侵犯深肌层模型12和侵犯临近组织模型13依次插接于胃壁凹槽8内，以模拟展示中晚期胃癌病理特点。
