Problems solved by technology
The known dredging device (eye nail) is usually a nail-shaped device with a through hole in the middle, through which the liquid in the eye flows out, and because the diameter of the through hole is very small, it will cause the through hole to be blocked after a period of use , the eye pin loses its effect
Surgical opening of holes in the membrane layer of the eyeball will not cause blockage, but as time goes by, the opening will gradually heal and lose the function of leaking fluid

Embodiment Construction
[0016] Specific embodiment 1 of the present invention, as figure 1 As shown, a self-clearing glaucoma nail includes an eye pin 1 for implanting into the eyeball. Usually, the outside of the eye pin 1 has threads for fixing the eye pin in the eyeball. The inside of the eye pin 1 has a through hole 6. A dredging part 4 is axially slidably installed in the through hole 6, and an elastic piece 3 that drives the dredging part 4 to slide towards the top of the eyenail 1 is installed between the dredging part 4 and the eye nail 1, and the elastic piece 3 is Installed on a disc body 2, the disc body 2 is detachably installed on the top of the eye nail 1, and a pushing part is also provided on the dredging part 4, the pushing part is located on the top of the eye nail and exposed outside the through hole 6, The exposed part is connected with the inner side of the elastic sheet 3 . In this embodiment, a plurality of cavities 5 are provided in the through hole, and the cavities 5 can co...

The invention discloses a self-dredging glaucomatous nail which is characterized by comprising a nail. A through hole is arranged inside the nail, a dredging component is axially slidably mounted in the through hole, an elastic component used for driving the dredging component to slide towards the top of the glaucomatous nail is mounted between the dredging component and the glaucomatous nail, a jacking portion is further arranged on the dredging component, and at least one part of the jacking portion is positioned on the top of the glaucomatous nail and is exposed out of the through hole. The self-dredging glaucomatous nail has the advantages that the jacking portion of the dredging component is pushed under the action of an eyelid of a patient, the dredging component is pushed to slide in the fine through hole, blockage of the through hole is effectively avoided, excessive liquid in an eye of the patient can be continuously drained out of the eye, and accordingly the intraocular pressure is controllably reduced.
Description
technical field [0001] The invention relates to an ophthalmic medical device, in particular to a self-dragging glaucoma nail for lowering intraocular pressure. Background technique [0002] Self-unclogging glaucoma nails are devices used to relieve the pressure in the eyes of glaucoma. When the intraocular pressure is too high, it will squeeze the internal structure of the eye and cause lesions. In order to reduce the internal pressure of the eye, it is possible to implant a dredging device on the wall of the eyeball or to use surgery to open the membrane layer of the eyeball, so that the inside of the eye The fluid gradually flows out, reducing the pressure in the eye. The known dredging device (eye nail) is usually a nail-shaped device with a through hole in the middle, through which the liquid in the eye flows out, and because the diameter of the through hole is very small, it will cause the through hole to be blocked after a period of use , the eye stud loses its effec...
