Embodiment Construction

[0029] The drawings illustrate various exemplary implementations of vitrectomy instruments (interchangeably referred to as "vitrecutters") with illumination capabilities that provide for selectively adjusting Ability to cut illuminated areas around the tip.

[0030] Figure 1A to Figure 1B A vitreous cutter 100 is shown and used as an example. The vitreous cutter 100 may include a housing 110 having a nose piece 115 extending therefrom. The vitreous cutter 100 may also include a hollow vitreous cutting probe or needle (hereinafter “probe”) 120 having an outer cutting member 121 . The proximal end of outer cutting member 121 may be received within or otherwise connected to housing 110 . The distal end 123 of the outer cutting member 121 includes a cutting tip 125 . Such as Figure 1C As shown in , in some implementations, probe 120 may also include an inner cutting member that is slidable within outer cutting member 121 . The inner cutting member 200 may have a cutting ed...

Abstract

A vitrector that includes an adjustable illumination aperture is described. The vitrector may include a probe and a light sleeve assembly extending along and substantially surrounding the probe. The light sleeve assembly may include a plurality of optical fibers. At least a portion of the optical fibers are operable to provide illumination so as to define an illumination aperture about the vitrectomy probe. A portion of the optical fibers may be encapsulated. The light sleeve assembly may be adjustable along a length of the probe, providing adjustment of the illumination aperture to increase or decrease an area of illumination provided thereby.

Description

[0001] Cross References to Related Applications [0002] This application requires November 1, 2012 Submitted U.S. provisional application serial number 61 / 721,216 priority of the provisional application, the contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates generally to the field of vitreotomes, and more particularly, to illuminated vitreotomes with adjustable illumination apertures for providing adjustment to the area of ​​illumination provided around the tip of the knife. Background technique [0004] Vitrectomy is typically used during ophthalmic surgery, such as vitreo-retinal surgery involving the surgical removal of the vitreous in the eye. The vitreous consists of the clear, colorless, gel-like substance that fills the interior of the eye from the iris to the retina. During some procedures to correct vision impairment, a vitrectomy is generally used to cut and remove a portion of the vitreous as needed ...
