Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to an illumination chopper, and more particularly to an illumination chopper in which a nucleus of a lens is operated into small pieces while visibility is secured through a chopper mounted on one end of an illuminator to form a predetermined angle with respect to an illuminator. 
       BACKGROUND ART 
       [0002]    In the medical field, an illuminator is generally mainly used when retinal surgery is conducted, and a chopper is used when cataract surgery is conducted. 
         [0003]    Here, an illuminator or a chopper is used separately according to the surgery, and in the process of the surgery, the operator conducts the surgery while gripping the illuminator or the chopper for surgery in one hand and gripping an illumination device or an auxiliary tool for securing the field of view in the other hand. 
         [0004]    That is, because the operator conducts surgery while gripping surgery tools in both hands in the above-mentioned surgery method, excessive force is applied to the hands of the operator, causing pain and deteriorating the accuracy of the surgery as well when the surgery is conducted for a long time. 
         [0005]    In addition, because an illumination device emits light to the diseased part of the patient from the outside, efficiency is degraded as compared with the emitted light.

Therefore, the definition of the terms should be made based on the overall contents of the specification. 
       First Embodiment 
       [0022]    Hereinafter, an illumination chopper  100  according to a first embodiment of the present invention will be described with reference to  FIGS. 1 and 2 . 
         [0023]    The illumination chopper  100  according to the first embodiment of the present invention includes an illuminator  110  that emits light, a chopper  120  that is mounted on one end of the illuminator  110  to form a predetermined angle with the illuminator  110 , a grip part  130  that surrounds the illuminator  110 , a power supply  140  that is electrically connected the illuminator  110 , and a power connection part  150  that electrically connects the illuminator  110  and the power supply  140 . 
         [0024]    The illuminator  110  includes a body  111 , a body hole  112 , and optical fibers  113 . 
         [0025]    The body  111  is a kind of a tool that is generally used when cataract surgery is conducted, and has the form of a hollow tube. The body  111  includes the body hole  112  through which light passes, and a plurality of optical fibers  113  for emitting light to the outside are situated in the interior of the body  111 . 
         [0026]    The body hole  112  is a hole situated inside the body  111 , and the plurality of optical fibers  113  are situated in the body hole  112 . 
         [0027]    The optical fibers  113  are situated in the interior of the body  111 , and light is emitted towards one end of the body  111 . 
         [0028]    The chopper  120  is mounted on one end of the illuminator  110  and is arranged to form a predetermined angle with the illuminator  110 . 
         [0029]    In more detail, as illustrated in  FIG. 1 , the chopper  120  may be arranged so as not to block light emitted from the optical fibers  113 . 
         [0030]    That is, in the first embodiment of the present invention, the predetermined angle is an acute angle, and the light emitted from the illuminator  110  illuminates the front side of the illuminator  110 . 
         [0031]    The coupling structure allows the operator to emit light into an eyeball by using the illuminator  110  to improve visibility, and to conduct cataract surgery with the chopper  120  at the same time. 
         [0032]    It is preferable that the grip part  130  is formed to surround the illuminator  110  and is formed of a resilient material. The grip part  130  helps the operator conduct cataract surgery or the like while the operator grips the grip part  130  with one hand thereof. 
         [0033]    The power supply  140  is a unit for supplying electric power to the optical fibers  113 , and is electrically connected to the power connection part  150 . The power supply  140  may be any unit that can supply electric power. 
         [0034]    The power connection part  150  is an electric wire that electrically connects the optical fibers  113  and the power supply  140 . 
       Second Embodiment 
       [0035]    Hereinafter, an illumination chopper  100 ′ according to a second embodiment of the present invention will be described with reference to  FIGS. 3 and 4 , in which all the elements except for the chopper  120 ′ are the same as those of the first embodiment and will be described with reference to the second embodiment of the present invention. 
         [0036]    The illumination chopper  100 ′ according to the second embodiment of the present invention includes an illuminator  110 ′ that emits light, a chopper  120 ′ that is mounted on one end of the illuminator  110 ′ to form a predetermined angle with respect to the illuminator  110 ′, a grip part  130 ′ that surrounds the illuminator  110 ′, a power supply  140 ′ that is electrically connected the illuminator  110 ′, and a power connection part  150 ′ that electrically connects the illuminator  110 ′ and the power supply  140 ′. 
         [0037]    The chopper  120 ′ is mounted on one end of the illuminator  110 ′ and is arranged to form a predetermined angle with respect to the illuminator  110 ′. 
         [0038]    That is, in the second embodiment of the present invention, the predetermined angle is an obtuse angle, and the light emitted from the illuminator  110 ′ is refracted by the chopper  120 ′ to illuminate a periphery of the chopper  120 ′. 
         [0039]    In more detail, as illustrated in  FIG. 3 , the chopper  120 ′ is configured such that the light emitted from the optical fibers  113 ′ is refracted by the chopper  120 ′ so that the field of view around the chopper  120 ′ is secured. 
         [0040]    The coupling structure allows the operator to emit light into an eyeball by using the illuminator  110 ′ to improve visibility, and to conduct cataract surgery with the chopper  120 ′ at the same time. 
         [0041]    Here, the choppers  120  and  120 ′ according to the first and second embodiments of the present invention are somewhat different in the coupling relationships with the illuminators  110  and  110 ′, and it is apparent that the structure may be fixed after being variably adjusted to provide the operator with convenience during cataract surgery. 
         [0042]    Although the present invention has been described with reference to the preferred embodiments of the present invention, it will be understood that the present invention may be variously corrected and modified by those skilled in the art to which the present invention pertains without departing from the spirit and area described in the claims.
