Abstract: An endoscopic instrument includes: a body extending in a lengthwise direction, and having a first channel and a second channel parallel to each other; and an optical portion provided with an incident surface formed at an end part of the first channel so as to receive an external image, the optical portion disposed at the first channel, wherein the second channel is formed such that a laser module is insertable thereinto, and the laser module is configured to output laser in a direction crossing the lengthwise direction, and wherein the incident surface is formed to be inclined from a sectional surface of the first channel, such that the optical portion captures an image disposed on a path of the outputted laser. With such a configuration, a surgery can be performed through a single punched hole.
