A pre-type adjustable electromagnetic drainage valve for treating glaucoma

Abstract

The invention discloses a pre-type adjustable electromagnetic drainage valve for treating glaucoma, comprising a drainage plate, a drainage tube is arranged on the drainage plate, a drainage valve is arranged in the drainage tube, the drainage valve includes a magnetic valve block, and the magnetic valve block is There is a guide column, and a fixed block is provided on the drainage tube wall of the drainage tube. The guide column is sleeved through the fixed block. One end of the guide column is connected with the magnetic valve block, and the other end of the guide column is provided with a hard tip. The inner diameter of the drainage tube is along the The direction from the guide column to the magnetic valve block gradually decreases, and the wall of the drainage tube is in close contact with the outer periphery of the magnetic valve block. It also includes an external electromagnetic pole, and the external electromagnet is magnetically matched with the drainage valve. By changing the magnetic flux of the external electromagnet Control the movement of the diversion valve. The present invention can adjust the drainage volume of the drainage tube according to the actual use requirements through the cooperation of the external electromagnet and the magnetic valve block, and can also avoid the blockage of the lumen caused by tissue fibrosis, thereby realizing self-dredging and reducing the cost of 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...
