An endoscope according to the present invention includes first to fourth curved wire units which move in the forward/backward directions or the backward/forward directions in a rectilinear manner to change the direction of a front end of the endoscope to any direction, a first curved driving unit which rotates in the forward/reverse directions in accordance with a control signal to move the first or second curved wire unit in the forward/backward directions or the backward/forward directions in a rectilinear manner, a second curved driving unit which rotates in the forward/reverse directions in accordance with a control signal to move the third or fourth curved wire unit in the forward/backward directions or the backward/forward directions in a rectilinear manner, first to fourth curved wire guiding tube units for guiding the first to fourth curved wire units, respectively, and a control unit for applying control signals to the first or second curved driving unit in accordance with key signals for every direction. The endoscope of the present invention allows for ease of sterilization of a flexible insertion unit and prevents erroneous operation of the endoscope by eliminating the necessity of arranging an internal electronic element in the flexible insertion unit. |
