Endoscope with variable direction of view

摘要

Provided is an endoscope with a handle, an endoscope shaft connected to the handle, and imaging optics arranged in the endoscope shaft. An object can be located in the direction of view of the imaging optics in front of the endoscope shaft. The endoscope may also include a swivellably housed deflecting element that sets the desired direction of view. The deflecting element can be positioned at the distal end of the endoscope shaft facing away from the handle. An actuating element can be attached to the handle, which is mechanically connected to the deflecting element, and with which the swivel position of the deflecting element can be changed in order to set a desired direction of view.

1. An endoscope, comprising:
a handle; an endoscope shaft connected to the handle; imaging optics arranged in the endoscope shaft with which an object located in the direction of view of the imaging optics in front of the endoscope shaft is imaged as an image and which has a swivellably housed deflecting element to set the desired direction of view, said deflecting element is positioned at the distal end of the endoscope shaft facing away from the handle; and an actuating element attached to the handle which is mechanically connected to the deflecting element and with which the swivel position of the deflecting element can be changed in order to set a desired direction of view, wherein a sliding element, the proximal end of which is connected to the actuating element and the distal end of which forms a screening section, is arranged displaceable in the endoscope shaft, wherein an actuation of the actuating element leads to a displacement of the sliding element, and wherein the distal end of the sliding element is connected to the deflecting element such that a displacement of the sliding element brings about a change in the swivel position of the deflecting element and simultaneously a displacement of the screening section, in order to achieve, at the same time as setting the desired direction of view, a scattered-light screening for the area between the deflecting element and an optical element following the deflecting element of the imaging optics.
