Minimally invasive implanted aqueous humor diverter

Abstract

The invention provides a minimally invasive implanted aqueous humor diverter, which is used for communicating an anterior chamber with a suprachoroidal space or communicating the anterior chamber with a subconjunctival space to additionally establish a drainage bypass, so that the outflow of aqueous humor is increased, and the symptoms of glaucoma are relieved. The split-flow pipe comprises a split-flow pipe with an axial through hole, the split-flow pipe is provided with a body pipe part and a protruding ring part, a flange extending outwards in the circumferential direction of the periphery of the body pipe part is formed on the protruding ring part, the protruding ring part is arranged at the head end of the body pipe part, and the protruding ring part is provided with a first ring section; the outer diameter of the first ring section is larger than that of the body pipe part, and the inner diameter of the first ring section is larger than that of the body pipe part, that is, the diameter of the axial through hole in the head end hole section of the first ring section is larger than that of the axial through hole in the inner hole section of the body pipe part. When the head end hole section extends towards the inner hole section, the radial size is gradually reduced to form a horn mouth structure. The head end of the aqueous humor flow divider is provided with the protruding ring, the outer diameter is large, the inner diameter is slightly larger than that of the middle section of the flow divider, a horn mouth is formed, and drainage is accelerated.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a minimally invasive implanted aqueous humor shunt. Background technique [0002] Minimally invasive glaucoma surgery (MIGS) is an emerging type of minimally invasive glaucoma surgery, which refers to reducing intraocular pressure by improving the outflow of aqueous humor without damaging the sclera and conjunctiva of patients. Relieve glaucoma symptoms. Although traditional glaucoma treatment methods can effectively reduce intraocular pressure, common problems such as shallow anterior chamber and choroidal detachment are prone to occur in the early postoperative period, and long-term complications are also prone to occur. Compared with traditional surgery, MIGS has obvious advantages such as less trauma, accurate curative effect, high safety, quick recovery, and low risk of complications, and can reduce the use of postoperative anti-glaucoma drugs. In recent...

Problems solved by technology

However, none of the above-mentioned patent documents gave sufficient consideration to the continuity of the shunt pathway caused by the pressure of the scleral protrusion during use of the aqueous humor drainage device and the stability of the drainage system caused by the activity of the ciliary muscle.
