Problems solved by technology

Viscoelastic tubule dilatation is to expand Schlemm's canal by injecting viscoelastic agent in Schlemm's canal, but viscoelastic agent cannot exist in the lesion for a long time, and the effect is short-lived. If it is washed away, it cannot Play a role
Angioplasty has high technical requirements for doctors, and the results of the operation vary greatly among individuals, the reproducibility is poor, and it is accompanied by complications

Abstract

The invention relates to a schlemm tube stand with indication and push function, which belongs to the technological field of ophthalmic surgical stand. The schlemm tube stand with indication and push function comprises stand body, guide apparatus connecting with the stand body. The stand body is hollow tubular structure and is provided with a gap across to the top and the end. The stand body is provided with a notch, and the head end of the stand body is provided with a limited opening. The guide apparatus comprises a catheter, connector, fiber optic, and injection device. One end of the catheter is provided with a spacing groove and is connected with limited opening of the stand body through the spacing groove. The other end of the catheter is connected with the connector, and the connector is provided with two channels, one is an injection channels, and the other is an optical fiber channel. The optical fiber channel is connected with a laser generator, and the pipe is provided with an optical fiber. The schlemn tube stand used for expanding application of schlemn tube surgery can play the effect of Schlemm tube expansion for a long time. The presence of the optical fiber can indicate the position of the stand in the implantation process in real time, which brings great convenience to the operation, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of a stent for eye surgery, in particular to a Schlemm's canal stent with an indication push function. Background technique [0002] Glaucoma is a common eye disease and one of the three major blinding diseases that cause blindness in humans. Glaucoma is usually caused by the destruction of the dynamic balance of the aqueous humor circulation and poor drainage of the aqueous humor, resulting in elevated intraocular pressure. Sustained high intraocular pressure can cause damage to various parts of the eyeball and visual function. If it is not treated in time, the vision will be impaired Lost all to blindness. [0003] Under normal circumstances, aqueous humor drains from the posterior chamber to the anterior chamber, passes through the trabecular meshwork, enters Schlemm's canal, and then drains from Schlemm's canal into the scleral venous system to enter the blood circulation. When the lumen of Schlemm's c...
