Problems solved by technology

[0003] However, this implant can only cooperate with a special puncture mechanism. After the eye is punctured by the puncture mechanism, the implant is sent into the eye. The opening and supporting performance of the intraocular fluid outlet channel is poor, and it is easy to be blocked by intraocular tissue
Moreover, the above-mentioned products are more suitable for use in open-angle glaucoma, and the glaucoma in China is mainly angle-closure glaucoma, which accounts for about 90%, resulting in relatively little application of the above-mentioned products in China

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the embodiments given in the accompanying drawings.

[0021] see Figure 1-Figure 2 , the present invention provides a technical solution: an implant for increasing the outflow of aqueous humor, comprising an arc-shaped tubular body 1, a plurality of first drainage holes 11 are opened on the outer side wall of the tubular body 1, and the tubular body A plurality of second drainage holes 12 are opened on the inner side wall of the tube body 1 , and a puncture part 13 is provided at one end of the tube body 1 .

[0022] The implant is designed in a tubular shape, and after being implanted in the eye, the tube body 1 has a better expansion and support effect on the intraocular assembly, preventing the drainage channel from being blocked by the intraocular assembly, and keeping the drainage channel unobstructed.

[0023] A notch 14 is provided on the side wall of the inner side of the end o...

Abstract

The invention discloses an implant for increasing outflow of aqueous humor and a production method of the implant. The implant comprises an arc-shaped tube body; a plurality of first drainage holes are formed in the side wall of the outer side of the tube body; a plurality of second drainage holes are formed in the side wall of the inner side of the tube body; and a puncture part is arranged at one end of the tube body. The implant is designed to be tubular, after the implant is implanted into the eye, the tube body has better expanding and supporting effects on tissues in the eye, a flow guide channel is prevented from being blocked by the tissues in the eye, and the flow guide channel can be kept unobstructed. And the implant is more suitable for closed-angle glaucoma and is more suitable for Chinese patients.

Description

technical field [0001] The invention relates to the technical field of ophthalmic medical devices, and relates to an implant for increasing aqueous humor outflow and a production method for the implant. Background technique [0002] U.S. Patent (Patent No.: US9351874B2) discloses a method and device for delivering an ocular implant into the eye. It is also arc-shaped, and the implant has a convex structure on the outside of the arc, and a diversion hole is opened on the inside of the implant. [0003] However, this implant can only cooperate with a special puncture mechanism. After the eye is punctured by the puncture mechanism, the implant is sent into the eye. The opening and supporting performance of the intraocular fluid outlet channel is poor, and it is easy to be blocked by intraocular tissue. And the above-mentioned products are more suitable for use in open-angle glaucoma, and the glaucoma in China is mainly closed-angle glaucoma, which accounts for about 90%, resu...
