Front-arranged adjustable electromagnetic drainage valve for treating glaucoma

Abstract

The present invention discloses a front-arranged adjustable electromagnetic drainage valve for treating glaucoma. The front-arranged adjustable electromagnetic drainage valve for treating the glaucomacomprises a drainage disk, a drainage tube is arranged on the drainage disk, a drainage valve is arranged in the drainage tube, the drainage valve comprises a magnetic valve block, guide posts are arranged on the magnetic valve block, fixed blocks are arranged on drainage tube wall of the drainage tube, the guide posts are sleeved and penetrate through the fixed blocks, one ends of the guide posts are connected with the magnetic valve block, the other ends of the guide posts are provided with hard tips, an inner diameter of the drainage tube is gradually reduced along a direction from the guide posts to the magnetic valve block, the drainage tube wall is closely abutted with a periphery of the magnetic valve block, the front-arranged adjustable electromagnetic drainage valve also comprises an external electromagnetic pole, an external electromagnet is magnetically matched with the drainage valve, and magnetic flux of the external electromagnet is changed to control movement of the drainage valve. The front-arranged adjustable electromagnetic drainage valve can adjust drainage quantity of the drainage tube according to actual use requirements through matching of the external electromagnet and the magnetic valve block, can also avoid tube cavity blockage caused by tissue fibrosis, thus realizes self-dredging and reduces a surgery failure rate.

Description

technical field [0001] The invention relates to the technical field of glaucoma treatment devices, in particular to a pre-type adjustable electromagnetic drainage valve for treating glaucoma. Background technique [0002] Glaucoma is the second irreversible blinding eye disease in the world, and it is also one of the main blinding eye diseases in my country. The intraocular pressure (IOP) will increase due to the imbalance between the production and discharge of aqueous humor. When the intraocular pressure (IOP) increases When the time is higher than normal pressure, it can cause irreversible damage to the optic nerve and retinal fibers, causing the patient's vision to decrease or even cause permanent damage. [0003] For refractory glaucoma, the most commonly used at home and abroad is the anterior chamber catheter-type glaucoma drainage valve implantation, and the front-mounted glaucoma drainage valve is widely used in clinical practice, mainly represented by the trade name...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a pre-type adjustable electromagnetic drainage valve for the treatment of glaucoma, which not only solves the problem of controlling the intraocular pressure of patients by controlling the drainage volume of the drainage tube, but also solves the problem caused by tissue fibrosis. drainage tube blockage
