Description
技术领域
本发明涉及一种简易泪道义管及其使用方法，属于医疗器械技术领域。
背景技术
泪腺产生的泪液湿润眼表后，通过泪小点-泪小管-泪总管-泪囊-鼻泪管流入鼻腔，泪道引流系统发生功能性障碍而导致溢泪，长期溢泪眼睛内眦部皮肤潮红、发生湿疹，患者不断向下揩拭眼泪二造成下睑外翻和流脓造成角膜感染、视力下降、甚至视力丧失。造成溢泪的原因较多，其中泪小管断裂、泪道狭窄、泪道阻塞等泪道疾病，使泪道系统无法再通，惟有通过泪旁道义管引流泪液。目前泪道疾病所应用的义管包括如下几个方面：1)使用腰麻管自下泪小点或上泪小点至鼻泪管开口顺行植入管道，缺点是固定困难，常使用胶带黏贴，风险固定等等，容易脱落，过敏等；影响患者外观；管道为硬管道，容易外翻及引起泪小点撕裂；2)RS管，该管道为双径路环形管道，不管患者是否为上下泪小管都有问题，该系统都要进行双泪小管植入管道(如图1所示：6为RS管)，对患者的健康端泪小管容易造成医源性损伤；该管道为环形管道，管道无孔隙，植入后眼泪无法引流，患者取出植入管前还是会有流泪的症状，而且植入后无法验证义管是否在泪道内；3)自鼻泪道开口处逆行植入义管，缺点是植入困难，眼科大夫不易完成，需耳鼻喉科大夫合作，容易损伤鼻粘膜。
发明内容
本发明所要解决的技术问题是针对现有技术存在的缺陷，提供一种结构简单、操作方便的泪道义管及使用方法。
为解决这一技术问题，本发明提供了一种简易泪道义管，包括硅胶管道以及内置探针，硅胶管道的末端设有开口，其上端为U形翅膀状；其中硅胶管道管径为2mm，内径为1.8mm，长4cm，内置探针2为1.8mm粗，长度与硅胶管道同长。
所述U形翅膀状模拟泪小点处眼部解剖形状，设有U形开口。
所述硅胶管道的管身设有刻度标记。
本发明还提供了一种简易泪道义管的使用方法，具体包括如下步骤:
1)将硅胶管道和内置探针组在一起；
2)对于上泪小管断裂，自上泪小点进入，从颞侧断端处出来，然后进入鼻侧断端，最后进入鼻泪管；如下泪小管断裂步骤同上；如上下泪小管都有断裂，植入两根管道即可；
对于上泪道狭窄，自上泪小点进入，进入鼻泪管；如下泪道狭窄，则自下泪小点进入，进入鼻泪管；如上下泪道均狭窄，则需植入两根管道；
3)然后自探针口注入盐水，看是否在泪小管内，如在管道内，将探针拔出，将硅胶管道留在原处。
有益效果：本发明采用简易的分解义管，应用于泪小管断裂、泪道狭窄、泪道阻塞等泪道疾病治疗，能够完美解决义管固定、植入困难、泪道损伤等植入中的问题，义管末端及上端的开口，可以解决泪液引流问题；本发明植入简单、易行，尤其对初学者也无太大技术难度。

图4所示为本发明U形翅膀状的结构示意图。
所述U形翅膀状4模拟泪小点处眼部解剖形状，设有U形开口5。
所述硅胶管道1的管身设有刻度标记。
本发明简易泪道义管的使用方法，具体包括如下步骤:
1)将硅胶管道1和内置探针2组在一起；
2)对于上泪小管断裂，自上泪小点进入，从颞侧断端处出来，然后进入鼻侧断端，最后进入鼻泪管；如下泪小管断裂步骤同上；如上下泪小管都有断裂，植入两根管道即可；
对于上泪道狭窄，自上泪小点进入，进入鼻泪管；如下泪道狭窄，则自下泪小点进入，进入鼻泪管；如上下泪道均狭窄，则需植入两根管道；
3)然后自探针口注入盐水，看是否在泪小管内，如在管道内，将探针拔出，将硅胶管道1留在原处。
本发明采用简易的分解义管，应用于泪小管断裂、泪道狭窄、泪道阻塞等泪道疾病治疗，能够完美解决义管固定、植入困难、泪道损伤等植入中的问题，义管末端及上端的开口，可以解决泪液引流问题；本发明植入简单、易行，尤其对初学者也无太大技术难度。
