Abstract

The present invention relates to a device for three dimensional endoscopic surgery, and more specifically, to a device for three dimensional endoscopic surgery, wherein therapeutic tools including an endoscope can be inserted into the human body through one main tube, and the therapeutic tools can be spread outward to be utilized in the human body, thereby minimizing an incision site in case of surgical operation while allowing various medical operations to be performed using one main tube. The present invention is a device for endoscopic surgery comprising: a main tube which is inserted into the body of a patient; first and second cameras which are inserted in a row into the main tube; a light source portion which is inserted between the first and second cameras; and a therapeutic tool which is located below the second camera to be inserted into the main tube.
