Abstract

The invention discloses an injector, which is used for pushing a glaucoma drainage implant into an schlemm tube, and comprises a shell, a guide tube, a pushing mechanism and a pushing wire, the guide tube is connected with the shell, the far end of the guide tube is used for containing a glaucoma drainage implant, the push wire is arranged in the guide tube, the far end of the push wire abuts against the glaucoma drainage implant, and the near end of the push wire is exposed out of the near end of the guide tube and is connected with a push mechanism in the shell; at least part of the pushing mechanism is exposed out of the shell and used for providing pushing force for the pushing wire so that the glaucoma drainage implant can be pushed into the schlemm tube along the guide tube, and in the pushing process of the pushing mechanism, the far end of the guide tube abuts against the outside of the schlemm tube. The injector is good in pushing effect, high in precision and convenient for an operator to use.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a bolus injector. Background technique [0002] Glaucoma is a group of diseases characterized by atrophy and depression of the optic nerve head, visual field defect and vision loss. Sex is also associated with the development and progression of glaucoma. Any obstruction in 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 of 1% in the general population and 2% after the age of 45. Clinically, glaucoma is divided into three categories: primary, secondary and congenital according to the etiology, angle of the chamber, intraocular pressure and other conditions. [0003] In the prior art, a drainage implant is usually implanted inside ...
