AI Technical Summary

Benefits of technology

The present invention is about a phacoemulsification device used for eye surgery that has a cooling aperture ports to provide cooling to the eye during surgery. The device includes a handpiece, an aspiration needle, an irrigation sleeve, and an irrigation port. The device can maintain balanced intraocular pressure by replacing the volume of lens material with irrigation fluid. The device can also have an aperture that directs the fluid towards the eye at an accelerated rate if the flow of fluid is reduced. The technical effect of the invention is to provide better cooling and protection for the eye during eye surgery using a phacoemulsification device.

Problems solved by technology

The ultrasonic vibration of the phaco needle creates a significant temperature rise of the needle.
On occasion, large chunks of ocular material clog the phaco needle, which interrupts the aspiration flow, which in turn causes interruption in the irrigation flow.
Though the irrigation flow is interrupted, the phaco needle may still be vibrating causing localized heating and potential localized burning of the eye.

Embodiment Construction

[0017]Initially, this disclosure is by way of example only, not by limitation. Thus, although the instrumentalities described herein are for the convenience of explanation, shown and described with respect to exemplary embodiments, it will be appreciated that the principles herein may be applied equally in other types of situations involving eye surgery.

[0018]To illustrate an exemplary environment in which preferred embodiments of the present invention can be practiced, FIG. 1A depicts an embodiment of a phacoemulsification device 100 consistent with embodiments of the present invention. As shown the phacoemulsification device 100 generally comprises a handpiece 114, a hollow aspiration needle 106 extending from the handpiece 114, an irrigation sleeve 104 that surrounds a portion of the aspiration needle 106 (also known as a phacoemulsification needle), at least one irrigation port 102 extending through the irrigation sleeve 104, a hub 112, and at least one irrigation aperture 110 i...

Abstract

Described is a phacoemulsification device for eye surgery that generally comprises an ultrasonically vibrating aspiration needle that withdraws ocular material from inside of the eye. The ocular material withdrawn from the eye is equally replaced with irrigation fluid provided through irrigation ports in an irrigation sleeve surrounding the aspiration needle. In the event the aspiration needle stops withdrawing ocular material, such as if it becomes occluded with a chunk of ocular material, irrigation fluid is directed to the outside of the eye via at least one irrigation aperture to keep the eye cool where the needle is ultrasonically vibrating.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to and the benefit of U.S. provisional Patent Application No. 61 / 861,879, entitled: Occlusion-Activated heat Suppression Infusion Sleeve, filed on Aug. 2, 2013 the entire disclosure of which is hereby incorporated by reference.FIELD OF THE INVENTION[0002]The present invention is directed to a phacoemulsification device with cooling aperture ports that is useful in providing cooling to an eye during cataract surgery.BACKGROUND OF THE INVENTION[0003]A cataract is the clouding of the eye's natural lens. The lens is mostly made up of water and protein. As we age, these proteins change and clump together obscuring the lens. Correcting this change is generally done by removing the cataract lens and replacing it with a clear lens implant. One way of correcting the effects of cataracts is through Phacoemulsification eye surgery.[0004]Phacoemulsification is a surgery technique on an eye wherein the internal lens is...
