The present invention relates to the field of medical devices and discloses an endoscope structure, which consists of a fixing ring, a connection tube and an operation tube connected in sequence, among which, the connection tube consists of braided layers, the connection tube can be bent, and the stiffness of the braided layers of the connection tube is inversely proportional to the maximum bending angle of the connection tube; the structure also consists of traction wires, the traction wires are fixed onto the fixing ring by the operation tube through the connection tube, and the connection tube will be bent by pulling the traction wires at the end of the operation tube. Main beneficial effects of the present invention are: the braided layers and traction wires are arranged inside the connection tube, so that the present invention has advantages of convenient connection, soft and controllable; the guide groove is arranged on the outer lateral walls of the support layers, the traction wires are respectively placed inside the guide groove, when the traction wires move, the guide groove plays a role of guiding and positioning to ensure that the traction wires only move along the length direction of it structure.
