Problems solved by technology
[0006] Although such curved sections have proven very successful in manufacture and use, there are some reasons why it is desirable to make the curved section longer and thinner (i.e. longer length and more segments and smaller outer diameter) the disadvantages caused by
More specifically, the channels or apertures for the pull wires become very narrow, and as the length increases, the retractable core used to provide these channels within the mold cavity during the molding process becomes very long and thin , so it is more likely to fail

Embodiment Construction
[0036] first go to Figure 7 , shows a system comprising a display unit 1 , such as a monitor with a screen, and an endoscope 2 connectable to the display unit via a wireless connection or a cable 3 . The endoscope 2 is preferably a disposable, ie, single use endoscope, which is to be discarded after use in a patient rather than being cleaned, sterilized and reused. The endoscope 2 comprises at a proximal end a handle 4 adapted to be grasped by the operator's hand, and a bendable insertion tube 5 extending towards the distal end of the endoscope 2 and adapted to be inserted into a patient's body . At the distal end of the insertion tube, the endoscope comprises a tip section, ie a main tube section, connected via an articulated curved section 6 to the rest of the insertion tube. The articulated bend section 6 is highly bendable compared to the main tube section. as in figure 1 As can be seen in , the bending movement of the bending section is controlled by the user using a...

An endoscope includes a handle at a proximal end, an insertion tube connected to the handle. The insertion tube includes a curved section. The curved section includes a first elongated curved section portion and a second elongated curved section portion. The first elongate curved section portion includes a plurality of first annular members. The first annular members are arranged in a row and connected to each other by a plurality of first bridges to form a first comb structure. The second elongate curved section portion includes a plurality of second annular members. The second annular members are arranged in a row and connected to each other by a plurality of second bridges to form a second comb structure. An outer circumferential surface of at least some of the first annular members includes a groove adapted to receive and receive a second bridge of the second curved section portion, and an outer circumferential surface of at least some of the second annular members includes a groove adapted to receive and receive a first bridge of the first curved section portion.
Description
technical field [0001] The present disclosure relates to endoscopes, and more particularly to articulating curved sections of insertion endoscopes and their manufacture. Background technique [0002] Endoscopes are well known devices for visual inspection of inaccessible locations such as body cavities of the human body. Typically, an endoscope includes an elongated insertion tube with a handle at its proximal end (from the operator's point of view) and a device such as a built-in camera at its distal end. Visually inspect the device. Wires for the camera and other electronics, such as LED lighting, run along the interior of the elongated insertion tube from the handle to a tip at the distal end. Instead of using a camera, the endoscope can also be fiber optic, in which case the fiber optics run along the inside of the elongated insertion tube. [0003] In order to be able to maneuver the endoscope inside a body cavity, the distal end of the endoscope may comprise a secti...
