Embodiment 1
[0047] First, refer to Figure 1 to Figure 5 , to describe the first embodiment of the present invention.
[0048] Figures 1 to 3 Each shows a view of the general structure of the first embodiment of the endoscopic lens 1 according to the present invention.
[0049]The endoscopic lens 1 includes an endoscopic lens main body 11 composed of a cylindrical base 11A on the proximal side and an extension portion 11B extending from the base 11A in the distal direction.
[0050] In the extension 11B, a lateral camera 16 and lighting means 17 are arranged in a known manner. At the distal end, the extension portion 11B has a rounded front surface 14 .
[0051] In the cylindrical base 11A, at least one working channel, a control line channel, and lines for supplying the camera 16 and the lighting device 17 and the like are provided.
[0052] At least the working channel and the control wire channel both extend in the longitudinal direction of the base body 11A and parallel to each o...
Embodiment 2
[0081] In the following, refer to Figure 6 to Figure 8 , to describe the second embodiment of the present invention. The general structure of the second embodiment corresponds to Figure 1 to Figure 3 icon in .
[0082] Figure 6 to Figure 8 A side view of the endoscopic lens body of the second embodiment is shown. As far as illustration is concerned, those elements of the second embodiment that are the same as those of the first embodiment will not be described in detail and have the same reference numerals.
[0083] In the following, differences compared with the first embodiment are mainly described. Unlike in the first embodiment, the pivoting element in the second embodiment is formed as a swivel joint 6 in the pivotable working channel element 30 .
[0084] On the proximal side, the pivotable working channel element 30 also comprises a proximal annular element 31 fixed on the distal surface 18 .
[0085] The proximal ring element 31 has a distal side on which the ...

Abstract
The present invention relates to an endoscope. The endoscope comprises an endoscope lens main body (11A, 11B). At least one working channel (13) is formed in the endoscope lens. There is a pivotable working channel end (30). The working channel end (30) is arranged to pivot relative to the endoscopic head body (11A, 11B).
Description
[0001] manual technical field [0002] The present invention relates to an endoscopic head comprising an endoscopic head body, wherein at least one working channel is formed, wherein on the distal side of the endoscopic head body a pivotable working channel element is provided. Furthermore, the present invention relates to an endoscope including such an endoscope lens, a cover for the endoscope, and a cover forming method. Background technique [0003] Such an endoscope lens body can be used for a duodenoscope, ie an endoscope for examining eg the esophagus or the duodenum, the bile duct, the gallbladder, the pancreatic duct, the pancreas and the like. [0004] With a duodenoscope, the duodenum can be reached through the esophagus, stomach, and pylorus. [0005] A duodenoscope includes lateral (side) optics (illuminators and cameras). This can complicate insertion and advancement of the duodenoscope through the esophagus, since "forward" viewing is not readily available. ...
