Embodiment Construction

[0021] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0022] as attached figure 1 , figure 2As shown, a puncture indwelling device for continuously balancing the pressure difference across the sieve plate, including a balance maintainer body 1, the bottom of the balance maintainer body 1 is provided with a limit plate 2, and the limit plate 2 Designed for disc-shaped settings or other shape structures, the diameter of the limit plate is larger than the diameter of the maintenance channel, and the diameter of the limit plate is about 300 μm, which is used to limit the pressure balance maintainer across the sieve plate and leave it in the perforation of the sieve plate. The limiting plate 2 is provided with a maintenance channel 3, and the maintenance channel 3 can be designed in a variety of shapes with a channel structure. The front end of the maintenance channel 3 is a top 31, and the top 31 ...

Abstract

The invention discloses a laminal cribrosa crossing pressure balance maintainer used for constantly balancing the laminal cribrosa crossing pressure difference, an implantation device and a method forbalancing the laminal cribrosa crossing pressure difference. The laminal cribrosa crossing pressure balance maintainer is placed to the laminal cribrosa and used for balancing the laminal cribrosa crossing pressure difference to make the deformed laminal cribrosa recover even reverse, the tolerance of glaucoma patients to intraocular hypertension is improved, nervous lesion caused by the laminalcribrosa crossing pressure difference is relieved and reduced, and primary factors of the glaucoma optic nerve lesion are eliminated. New ideas are provided for the treatment of the glaucoma in the middle-and-late period.

Description

technical field [0001] The invention mainly relates to the technical field of glaucoma treatment, in particular to a cross-sieve plate pressure balance maintainer and implantation device for continuously balancing the pressure difference across the sieve plate of glaucoma patients and a method for balancing the pressure difference across the sieve plate. Background technique [0002] Glaucoma is the world's largest irreversible blinding eye disease, mainly caused by pathological high intraocular pressure, a progressive optic neuropathy characterized by retinal ganglion cell apoptosis and gradual loss of visual function. Glaucoma is an age-related eye disease. As the average life expectancy increases, the prevalence of glaucoma will increase. By 2020, the number of glaucoma patients will increase to 80 million, and the number of glaucoma patients in China will reach 25 million. The age of onset tends to be younger; glaucoma is highly blinding, and pathological elevated intrao...
