Endoscope, in particular video endoscope

The present invention relates to an endoscope, in particular a video endoscope, having an endoscope shaft and having a mount for attaching an optical imaging device, for example a video camera, and having an endoscope housing between the endoscope shaft and the mount, the mount being rotatable relative to the endoscope shaft, via a rotary joint, about the longitudinal axis of the endoscope, an optically imaging arrangement, which is at least partially positionally displaceable by way of an adjusting device for focusing the image transmission, moreover being received in the endoscope housing. An endoscope, in particular a video endoscope, has an endoscope shaft at the distal end and a mount at the proximal end for attaching an optical imaging device, for example a video camera, and an endoscope housing between said endoscope shaft and said mount, said mount being rotatable relative to said endoscope shaft, via a rotary joint, about the longitudinal axis of said endoscope an optically imaging arrangement, which is at least partially positionally displaceable by way of an adjusting device for focusing the image transmission, moreover being received in said endoscope housing. Said endoscope housing is configured in continuously hermetically sealed fashion, and said rotary joint is arranged outside said endoscope housing.
