Abstract: A laser operation device includes an elongated catheter, a light irradiator configured to irradiate a laser in front of a tip of the catheter, a lens disposed at a front of the light irradiator and allowing the laser to pass therethrough, a wire configured to steering the lens by pulling one side of the lens, and an elastic body configured to give an elastic force to restore the lens against a tension of the wire, wherein when the lens is steered, the laser passes through the lens and is refracted.
