Claim 12:
13. A capsulorhexis device, which is a capsulorhexis device inserted into an incision site of a cornea to make an incision in a crystalline lens capsule surrounding a crystalline lens, the capsulorhexis device comprising:
a loop having elasticity and conductivity;
a moving member having one end fixed and coupled to the loop;
a head part including a housing configured to store the loop therein and an insertion guide coupled to one end portion of the housing to communicate therewith; and
a body that is coupled to the other end portion of the housing and has a sliding button provided to slide the loop and the moving member through the head part,
wherein, to make the incision in the crystalline lens capsule, a front end of the insertion guide is configured to be inserted through an incision site of a cornea, the head part provides a path along which the loop is moved to the outside through the insertion guide, and the loop slides to pass through the insertion guide from the housing, is unfolded into an anterior chamber of the eye that is below the cornea, and is configured to, using high-frequency power supplied thereto, make a circular incision in a site of the crystalline lens capsule that comes in contact with the loop;
wherein the loop is configured to be placed on a virtual plane same as the moving member when housed in the housing, and at least a portion of the loop deviates from the virtual plane while the loop slides together with the moving member and passes through the insertion guide;
wherein the loop is deployed into a circular shape and located on the virtual plane after passing through the insertion guide; and
wherein the moving member is configured to linearly move on the virtual plane, on which the moving member is housed in the housing, while the loop slides, the moving member being housed in the housing on the plane.
