Problems solved by technology

However, such endoscopes are mostly very sensitive due to the need for flexible bushings at the endoscope tip, can only be produced with great difficulty in autoclavable methods, and require frequent repairs

Embodiment Construction

[0050] exist figure 1 In the illustrated embodiment, the endoscope 1 according to the invention is formed as an endoscope 1 with a variable viewing direction and has a handle 2 and an endoscope tube 3 connected to the handle 2, the sleeve 4 of which can be exist figure 1 See you in

[0051] as available from figure 2 In the enlarged sectional view of the distal end 5 of the middle endoscope tube 3 it is observed in particular that an optics tube 6 is provided, which is located in the inner tube 7 . An inner tube 7 for its components is arranged inside the sleeve 4 . An adapter 8 is inserted at the distal end of the inner tube 7 , the distal end of which is formed as a mount for the front lens 9 .

[0052] The front lens 9 is welded to the adapter 8, here formed as a sapphire concave lens, the adapter 8 for its parts is welded to said inner tube, the result of which is the distal end of the inner tube 7 and thus the distal end of the optics tube 6. The ends are tightly an...

Abstract

An endoscope with a variable direction of view is provided, which includes an endoscope shaft (3) and imaging optics (12) arranged inside the endoscope shaft (3). These image an object located before the distal end (5) of the endoscope (1) and produce an image of the object in the proximal area of the endoscope (1) in which a field stop (14) is arranged. The produced image (B) is larger than the field stop (14). In the proximal area of the endoscope an image module (17, 13; 17, 29) is arranged with which the relative position between the produced image (B)and the field stop (14) can be changed for changing the section of the produced image visible after the field stop (14) in order to change the direction of view of the endoscope.

Description

technical field [0001] The invention relates to an endoscope with a variable viewing direction by virtue of the preamble features of claim 1 . Background technique [0002] Such endoscopes typically have a rotatable mirror or rotatable prism in the distal end of the endoscope in order to change the viewing direction. Providing a rotatable mirror or a rotatable prism in the distal end of the endoscope requires more mechanical effort. And there always still needs to be enough space for rotation, and the entire endoscope including the rotation mechanism still has to be producible itself, which has limitations on miniaturization. [0003] Furthermore, the endoscope can also be formed in such a way that the entire endoscope tip can be bent outwards in order to change the viewing direction. In this case there is a flexible imaging conductor or imaging sensor disposed within the tip of the endoscope. However, such endoscopes are mostly very sensitive due to the need for flexible...
