Illumination chopper

Abstract

The present invention provides an illumination chopper which allows a user to operate on the nucleus of a crystalline lens with a small piece while securing visibility through a chopper which is mounted at one end of an illuminator to form a predetermined angle with the illuminator.

What is claimed is: 
     
         1 . A device for use in eye surgery comprising:
 an illuminator including a first end and a second end and being configured to emit light through the second end; and   a chopper that is fixedly mounted to the illuminator while being bent in a substantially downward direction at a predetermined angle with respect to the illuminator.   
     
     
         2 . The device of  claim 1 , wherein the predetermined angle is an obtuse angle. 
     
     
         3 . The device of  claim 1 , wherein the predetermined angle is a substantially right angle. 
     
     
         4 . The device of  claim 1 , wherein the chopper has an oval cross-section. 
     
     
         5 . The device of  claim 1 , wherein the illuminator and the chopper are integrally formed. 
     
     
         6 . The device of  claim 1 , further comprising an optical fiber connected to the illuminator for transmitting the light therethrough. 
     
     
         7 . The device of  claim 1 , further comprising a grip part that surrounds at least a portion of the illuminator. 
     
     
         8 . The device of  claim 7 , wherein the illuminator, the chopper, and the grip part are integrally formed.
