Endoscope with variable view angle

摘要

The endoscope has an endoscope shaft connected with a handle, and a projection lens (4) imaging an object as an image, where the object is provided in a viewing direction (5) of the lens in front of the shaft. The lens has a deflective prism (7) pivotally supported for adjusting the viewing direction. A marking diaphragm is mechanically coupled with an actuating element so that the diaphragm is moved with change of pivot adjustment of the prism and indicates the adjusted viewing direction by its visible position during examination of the image. A light source i.e. LED, is provided at a distal end of the endoscope shaft.
