摘要
The present invention relates to a lenticule extraction tool for smile surgery. According to the present invention, the amount of cornea lenticule excision can be minimized depending on a surgery subjects eyesight and cornea stiffness, and cornea lenticule separation can be reliably performed even in the case of very small thickness and angle of the outside circumferential surface of the cornea lenticule for surgery quality improvement. The lenticule extraction tool for smile surgery includes a guide tip and a grip connected to the guide tip and formed to be gripped by a surgeon. The guide tip ensures a space for an inward movement of a scraper by lifting from an inner skin tissue of a cornea stroma a lower part of a lenticule surface, which is a part of the outside circumferential surface of the cornea lenticule separated from the cornea stroma and forming an acute angle. The scraper cuts a tissue bridge present between the inner skin tissue of the cornea stroma and the cornea lenticule by alternately moving into a space between a flap surface as an upper surface of the cornea lenticule and the inner skin tissue of the cornea stroma in contact therewith and a space between the lenticule surface as the lower surface of the cornea lenticule and the inner skin tissue of the cornea stroma in contact therewith when the cornea lenticule is separated from the cornea stroma by femtosecond laser being transmitted through the surface of the cornea during smile surgery in which the thickness and position of the cornea lenticule is selectively adjusted that is to be excised by the use of the femtosecond laser.
