Abstract

The invention discloses a microporous drainage device for ophthalmic surgery and a conveying system thereof. The drainage device comprises a drainage valve body, wherein the drainage valve body is provided with a fixing part, a first drainage part and a second drainage part; the first drainage part is arranged on one side of the fixing part and is used for being inserted into an anterior chamber tubule of an eyeball of a patient; the second drainage part is arranged on the other side, opposite to the first drainage part, of the fixing part and is used for being connected with a vein tubule of the eyeball of the patient; and a microporous drainage channel is formed in the drainage valve body. The conveying system of the microporous drainage device for the ophthalmic surgery comprises a hollow handheld rod, wherein an operating head and a pull wire rod are respectively arranged at two ends of the handheld rod; a suture penetrates through the handheld rod and is provided with a closed annular part and a pull wire part; the closed annular part is embedded into the operating head; and the pull wire part is fixed with the pull wire rod. According to the microporous drainage device for the ophthalmic surgery, the problem of high intraocular pressure of glaucoma can be solved, and various inflammation problems caused by implantation of a common drainage valve are avoided, so that the glaucoma disease is safely and efficiently treated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a microporous drainage device for ophthalmic surgery and a delivery system thereof. Background technique [0002] At present, among ophthalmic diseases, glaucoma is the second most irreversible blinding eye disease in the world, and it is also one of the main blinding eye diseases in my country. The cause of glaucoma is mainly that the intraocular aqueous humor is not discharged smoothly, which leads to increased intraocular pressure, and eventually leads to nerve atrophy and blindness. For primary open-angle glaucoma, the most commonly used surgery at home and abroad is glaucoma drainage valve implantation. Aqueous humor is drained out by means of a drainage valve, but after a period of time, bleb leakage, scarring, blockage, low intraocular pressure, and bleb-related intraocular inflammation will become a patient's nightmare. In addition, the drainage valve is art...
