Description

Glaucoma drainage tube implantation system

Technical Field

The invention relates to the technical field of medical instruments, in particular to a glaucoma drainage tube implantation system.

Background

The pathological increase of intraocular pressure is a main risk factor of glaucoma, the reason of the increase of intraocular pressure of glaucoma is that the dynamic balance of the aqueous humor circulation is destroyed, the increased intraocular pressure causes optic nerve damage through two mechanisms of mechanical compression and optic nerve ischemia, and the longer the duration of the increase of intraocular pressure is, the more serious the damage of optic function is, resulting in irreversible visual field loss. In the treatment of glaucoma clinically, lowering intraocular pressure is considered to be the only treatment currently effective in controlling disease progression. Methods for reducing intraocular pressure generally include drug, laser and surgical treatments, while anti-glaucoma surgical treatment is an essential and ultimate treatment for the treatment of this disease. Currently, the traditional anti-glaucoma operation applied in clinic is trabeculectomy, in which a part of trabecular tissue is cut to establish a passage from the inside of an eye to the subconjunctival part outside the eye wall, so that aqueous humor in the eye flows out of the passage to achieve the effect of lowering intraocular pressure, and complications such as anterior chamber and choroidal detachment, bleb fibrosis, bleb infection and the like caused by the operation are inevitable problems. In order to improve the operation treatment mode, a novel minimally invasive drainage device implantation operation is rapidly developed, one end of the drainage device is guided and injected into the anterior chamber of the eye by using an implantation system, the other end of the drainage device is placed under the cornea, and an aqueous humor outflow channel is reconstructed by using the implantation drainage device, so that the intraocular pressure is reduced, and the purpose of treatment is achieved.
