Introducer for Schlemm's Angioplasty

Abstract

The invention discloses a guide device used for the Schlemm' scanal angioplasty. The guide device comprises a guide pin which is arc-shaped and has magnetism, wherein an implant connecting part used for connecting an implant is arranged on the guide pin. According to the guide device used for the Schlemm' scanal angioplasty, the guide pin is designed to have magnetism; during the operation, the guide pin is enabled to enter the eye, another outer guide piece attracting the guide pin through magnetism is used outside the eye for guiding the movement of the guide pin, and the movement of the guide pin drives the implant to move so as to complete the Schlemm' scanal angioplasty. The guide device is simple in structure and convenient to use, and the positioning guidance for the implant can be conveniently realized without medical fibers, therefore, the operation cost is greatly reduced, the burden of the patient is alleviated, and thus the clinical application prospect of the Schlemm' scanal angioplasty is improved.

Description

technical field [0001] The invention relates to a medical device, in particular to a guide for Schlemm's analoplasty. Background technique [0002] Glaucoma is an optic neuropathy (disease of the optic nerve) that usually results from poor drainage of the aqueous humor in the eye, resulting in increased intraocular pressure. The pressure in the eye increases, which damages the optic nerve and narrows the field of vision; when the patient has persistent high intraocular pressure, it can lead to blindness; Schlemm's canal angioplasty is a method of reducing intraocular pressure in glaucoma patients. One of the new surgical modalities in the United States, it uses the human eye's aqueous humor drainage system to safely treat elevated intraocular pressure; more specifically, Schlemm's annuloplasty uses an implant such as a microcatheter ) is placed in Schlemm's canal to expand the drainage channel, reduce intraocular pressure, and safely treat elevated intraocular pressure in g...

The pressure in the eye increases, which damages the optic nerve and narrows the field of vision; when the patient has persistent high intraocular pressure, it can lead to blindness; Schlemm's canal angioplasty is a method of reducing intraocular pressure in glaucoma patients. One of the new surgical modalities in the United States, it uses the human eye's aqueous humor drainage system to safely treat elevated intraocular pressure; more specifically, Schlemm's annuloplasty uses an implant such as a microcatheter ) is placed in Schlemm's canal to expand the drainage channel, reduce intraocular pressure, and safely treat elevated intraocular pressure in glaucoma patients by using the eye's conventional drainage system; published studies have shown that the long-term efficacy and safety of this operation are good, An effective surgical procedure for patients with open-angle glaucoma, especially those at high risk of infection or bleeding and complications of trabeculectomy; however, placement of the implant requires the use of specialized equipment including medical optics The introducer is expensive, which leads to extremely high operation cost and increases the burden on patients, thus limiting the clinical application prospect of this operation
