Problems solved by technology

The minimally invasive glaucoma surgery implants designed by most western developed countries are also designed for open-angle glaucoma with a high incidence in Caucasians, but cannot be used in patients with angle-closure glaucoma with a high incidence in my country

Embodiment Construction

[0037] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] A miniature glaucoma drainage implantation system includes two parts: an implant and an implant device.

[0039] Implants are hollow tubular structures (see figure 1 ), the front and rear openings are flush and blunt, and the total length is about 8mm (choose different lengths according to the selected implantation angle, for example, choose a shorter tube when it is perpendicular to the implantation site, and choose a shorter tube than the implantation site) Choose to use a longer tube when implanting at a small angle), the outer diameter of the tube is about 250-350 microns, and the inner diameter of the lumen is 60-200 microns. The materials used are materials with good biocompatibility, such as Poly (styrene-block-isobutylene-block-styrene, SIBS) which has been used in heart stents and gelatin derived from animal bodies.

Abstract

The invention discloses a miniature glaucoma drainage implant device and system. The implant system comprises an implant device and an implant made of materials which are good in biocompatibility. The miniature glaucoma drainage implant device and system can be used for open-angle glaucoma as well as goniosynechialysis glaucoma. The surgery that the implant device is utilized to implant the implant is simple, bulbar conjunctiva does not need to be opened, damage to the eye tissues is small, and thus a possibly caused fibrosis reaction is correspondingly reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a miniature glaucoma drainage implantation device and system. Background technique [0002] Glaucoma is the second leading cause of blindness worldwide. According to the report of the World Health Organization, there are 70 million people in the world suffering from glaucoma, and as the population ages, it is expected that this number will increase by 50% by 2020 (QuigleyHA, BromanAT.Thenumberofpeoplewithglaucomaworldwidein2010and2020.BrJOphthalmol.2006Mar; ):262-7.). Glaucoma is a group of diseases characterized by optic neuropathy accompanied by corresponding visual field defects, and the increase of intraocular pressure is one of the primary factors of the disease. In the clinical treatment of glaucoma, lowering intraocular pressure is considered to be the only effective treatment to control the progression of the disease. Generally speaking, the methods for lowering intraocular pressure...
