Embodiment Construction

[0033] specific implementation plan

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be further described in detail below in conjunction with the drawings in the embodiments of the present invention.

[0035] The present invention is a micro shunt device for treating glaucoma. The shunt device is an elongated member. When implanted, the first main flow opening of the shunt device is positioned in the anterior chamber of the eye, and the second end of the shunt device is The main orifice is placed in the retroocular space. Thus, the shunt is used to drain the aqueous humor from the anterior chamber of the eye to the retrobulbar space, providing the required passage for the fluid.

[0036] figure 1 , as shown in 2, the shunt device is a long member with variable shape, which includes a head end 1, a body portion 2, and a tail...

Abstract

The invention discloses a variable-structure glaucoma miniature shunt device which is characterized in that the shunt device is a shape-memory long component, the inside of the shunt device is in theshape of a hollow tube, comprises a head, a body and a tail and can be used as a fluid channel, the head is designed into a first main circulation opening in the design of an external expansion open tube, the outer diameter of a head port is 0.5-0.7mm, the port serves as an inflow opening, the body comprises a fixing part, a sub-flow channel and a second main circulation channel, and the tail is an extending channel. By the aid of the technical scheme, large injury and slow recovery of a traditional surgery are alleviated, secondary operation risks in a minimally invasive surgery are reduced,the problems of implantation misplacement, shifting, obstruction and the like are avoided, surgical safety is improved, and postoperative infection risks are reduced.

Description

technical field [0001] The invention relates to a device for ophthalmic treatment, in particular to a micro shunt device for glaucoma with variable structure. Background technique [0002] Glaucoma is an eye disease characterized by progressive, irreversible vision loss characterized by optic nerve damage. The mechanism of its occurrence is not yet clear, but it has at least been clearly related to elevated intraocular pressure (IOP), which is the third most common blindness disease in the world. At present, the prevalence of open-angle glaucoma among people over 40 years old in my country is 2.3%. The blinding rate is about 15%, and the disability rate is nearly 30%. Based on this calculation, with the acceleration of my country's population aging, it is estimated that by 2020, there will be 16.4 million open-angle glaucoma patients in China, resulting in nearly 2.46 million blind people and more than 4.9 million visually disabled people. Glaucoma can occur at any age, but...
