Claim 11:
12. A capsulorhexis device configured to be 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;
an insertion guide, which is a nozzle, configured so that, while the incision is being made in the crystalline lens capsule, a front end thereof is inserted into the incision site of the cornea; and
a housing having one end coupled to a rear end of the insertion guide,
wherein the loop is housed in the housing and, to make the incision in the crystalline lens capsule, can slide in the housing together with the moving member to pass through the insertion guide and be deployed into an anterior chamber of the eye,
wherein capsulorhexis device further comprises 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,
wherein a holder on which the moving member is mounted and which is coupled to the sliding button is installed in the body, and the other end of the moving member is fixed and coupled to the holder and linearly slides together with the holder by using the sliding button;
wherein a protruding part is formed on an inner wall of the body, a leaf spring is provided with the holder, and when the loop is stored in the housing, the leaf spring is disposed at a rear end of or at a rear of the protruding part to prevent unintentional sliding of the moving member and thereby allow the loop to be stored with the circular shape thereof being maintained;
wherein when the sliding button coupled to the holder, to which the moving member is fixed, is moved with a predetermined force or more, the leaf spring moves along one surface of the protruding part; and
wherein after a rear end of the leaf spring is caught at a front end of the protruding part, rearward movement of the moving member and the holder is prevented.
