The invention provides a drainage device for glaucoma valve filtering bleb position. The drainage device is composed of a drainage tube and a push-injection component, which is composed of a push-injection rod and a puncture needle. The push-injection rod is arranged in the front inner part of the drainage pipe, and the front end of the push-injection rod is provided with a puncture needle. The front end of the drainage tube is an oblique gradient transition plane for connecting the needle, and the rear part of the drainage tube is placed in the conjunctival sac or fascial sac. The front proximal end of the drainage tube is provided with an inverted needle reverse locking structure on the outer side of the tube wall. The advantages of the present invention are that the operation of implanting glaucoma valve wrapping bubble with the drainage device is simple, does not need to open glaucoma valve wrapping bubble, has little damage to eye tissue, is effective for wrapping caused by fibrosis, and can drain aqueous humor to lubricate the eye surface, and has an eye surface treatment effect for severe dry eye patients.
【技术实现步骤摘要】
青光眼阀引流装置
本专利技术涉及医药
,具体涉及一种用于青光眼阀滤过泡部位的引流装置。
技术介绍
青光眼是一种影响视网膜和视神经的眼部疾病,在世界范围内都是导致失明的主要原因之一。当眼压长时期增大到高于正常水平的压力时,导致青光眼。难治性青光眼治疗手术失败的主要原因是术区组织纤维化及癫痕形成,阻碍了房水的引流和扩散。目前,眼科医生控制难治性青光眼患者的眼压、特别是在治疗复杂青光眼时,经常采用青光眼引流装置,目前已有多种青光眼引流阀,其原理是借助植入前房的引流物建立房水引流和扩散的人工通路,将房水引流到结膜囊或筋膜囊,从而降低眼内压。青光眼引流阀使用一段时间后被机化膜包裹而逐渐丧失功能。目前的引流管或引流阀在被机化膜包裹而失效后往往只能通过手术打开包裹泡或更换引流装置。既增加了患者的痛苦和经济负担,也增加了感染的机会。因此,目前需要一种不用打开青光眼阀包裹泡而能够直接引流房水的装置。
