Abstract

The invention provides an injector which is used for pushing a glaucoma drainage implant into a schlemm tube. The injector comprises a shell, a guide rail and an adjusting assembly, a holding part anda head part connected to the holding part are arranged on the shell, and a through groove is formed in one end of the head part; the guide rail is arranged in the through groove and used for containing the glaucoma drainage implant and guiding pushing of the glaucoma drainage implant, and part of the guide rail protrudes out of the shell; and the adjusting assembly is at least partially exposed out of the head and used for providing pushing power, so that the glaucoma drainage implant can be pushed to the schlemm tube along the guide rail. The invention further provides a glaucoma drainage device. The glaucoma drainage device and the injector thereof are good in pushing effect and high in accuracy.

Description

technical field [0001] The application relates to the technical field of medical equipment, in particular to a glaucoma drainage device and an injector thereof. Background technique [0002] Glaucoma is a group of diseases characterized by optic disc atrophy and depression, visual field defect and vision loss. Pathological increased intraocular pressure and optic nerve insufficiency are the primary risk factors for its onset. The tolerance of optic nerve to pressure damage Sex has also been linked to the onset and progression of glaucoma. Obstacles in any part of the aqueous humor circulation pathway can lead to pathological changes caused by elevated intraocular pressure, but some patients also present with normal intraocular pressure glaucoma. Glaucoma is one of the three major blindness diseases that cause blindness in humans, with an incidence rate of 1% in the general population and 2% after the age of 45. Clinically, glaucoma is divided into three categories: primary...
