A conical shaped-optical fiber is provided. The optical fiber includes remote end that is formed as a conical shape similar to a pointed end of a pencil and thus the laser beams are accumulated on the remote end for cutting tissue similar to a knife end. Further, in order to send laser beams circlewise in a tissue to a side, the remote end of the optical fiber is formed as a conical shape and the angle of the conical shape is adjusted for laser beams not to be accumulated on the remote end but to be scattered. |
