Description

Surgical instrument for atrial angle separation and incision

Technical Field

The present utility model relates to the technical field of surgical instruments, and more particularly, to a surgical instrument for atrial angular separation and dissection.

Background

Glaucoma (glaucoma) is the leading irreversible blinding eye disease worldwide. With the continuous progress and innovation of medical technology, the treatment mode is being changed from traditional filtration surgery with complex surgery and more complications to glaucoma minimally invasive surgery (MINIMALLY INVASIVE glaucommumia surgery, abbreviated as MIGS) which is more in line with the physiological structure of eyes, simpler and more convenient to operate and obviously reduced in complications.

Anterior angular separation (goniosynechialysis, GSL) and angular atriotomy (goniotomy, GT; also known as Schlemm tube incision, or endo Lu Xiaoliang incision) are important techniques for the application of MIGS in the treatment of glaucoma. GSL can separate adhered iris and reopen the angle of the room, GT can increase aqueous outflow by cutting open the small beam network tissue of the disease, thus reducing intraocular pressure. Although there are a wide variety of surgical instruments currently on the market for these two technologies, including double-ended angle splitters for angle separation, superbreast nucleus hooks, intraocular lens positioning hooks, iris restorators, etc., as well as single and double-ended angle cutting blades for angle dissection, KDB double-edged trabecular meshwork resectors, TMH trabecular meshwork cutting blades (also known as valley hooks), retinal scraping hooks, 25G1ml syringe needles or self-made blades formed after bending of 26G capsulorhexis needle tips, etc. However, they have a general limitation in that the operation is not convenient enough, and the functions of these instruments are relatively single, and only the anterior chamber angle separation or the chamber angle incision operation can be performed.
