Abstract: An endoscope cleaning device is applied to an endoscope having a main body and a tube body connected to the main body. The endoscope cleaning device includes a frame, a receiving tank for receiving the tube body, a circulating module, and an operating module that is electrically connected to the circulating module. The receiving tank and the operating module are disposed on the frame. The circulating module is connected to a source of first solution supply, a source of second solution supply, and the receiving tank. The operating module is manipulated by a user to control the circulating module to transmit the solution provided by the source of first solution supply and the solution provided by the source of second solution supply to the receiving tank and then to drain the solution in the receiving tank out. A cleaning method of an endoscope by using the endoscope cleaning device is provided.

Abstract: A flexible interlocking structure for a handheld endoscope includes a flexible rod having an interlocking unit connected to its one end. The interlocking unit includes front, middle and rear joints each having a hollow portion. Each joint is formed with at least two guiding holes, locking tabs and locking notches. The engagement between the locking tabs and the locking notches of the adjacent joints constitutes the interlocking unit. Both ends of the flexible rod are connected to a handle portion and an inspection module respectively. A transmission cable and driving wires are disposed through the hollow portions and the guiding holes in such a manner that they are located between the inspection module and the handle portion. By operating a steering device of the handle portion, the driving wires pulls the front joints to cause the interlocking unit to bend accordingly, thereby controlling the rotation of the inspection module.

Abstract: The present invention relates to an industry endoscope with a rigid body, which includes a base, a rod and a handle portion. One end of the base is horizontally connected to the rod having a knob. The handle portion is vertically connected to the base. The free end of the rod is provided with an inspection module. The rotation of the knob and the rod causes the inspection module to rotate 360 degrees relative to its axial line. In this way, the inspection module can be inserted to a small channel for precise inspection.
