AI Technical Summary

Technical Problem

It is difficult to develop an easy-to-use, inexpensive, minimally invasive surgical instrument for performing an atrial anotomy to reduce intraocular pressure.

Method used

A microsurgical instrument is designed with a cutting device at the tip portion that can form a unique cleavage plane directly below the Schwarber line, thereby enhancing the discharge of the ocular hydroperitoneal water.

Benefits of technology

The device can safely and effectively cut trabecular tissue, improve aqueous humor flow, reduce intraocular pressure, and due to its design, it can minimize damage to intraocular structure.

Abstract

A surgical instrument (40, 40A) for performing an atrial angular incision procedure includes a hand grip (44, 44A) having an elongated configuration having a proximal end and a distal end. The instrument (40, 40A) comprises a tip (52, 52A) connected to the distal end (48, 48A) of the hand grip (44, 44A), the tip having cutting means for forming a trabecular cleavage plane that results in the formation of a remaining trabecular leaflet in the eye directly below the Schwarbelian line to enhance the discharge of aqueous humor from the eye. In one form, the cutting device includes a pair of inclined arcuate cutting surfaces (70, 70A) that engage to define an arcuate cutting edge (74, 74A).
