Endoscope, in particular video endoscope
First Claim
1. An endoscope, comprisingan endoscope shaft, a mount for attaching an optical imaging device, and endoscope housing arranged between said endoscope shaft and said mount, an optical imaging arrangement disposed inside said endoscope housing and being at least partially positionally displaceable, an adjusting device for positionally displacing said optical imaging arrangement for focusing the image transmission, said mount being rotatable relative to said endoscope shaft via a rotary joint about a longitudinal axis of said endoscope, wherein said endoscope housing is configured in continuously hermetically sealed fashion and said rotary joint is arranged outside said endoscope housing and is configured at said mount.

Abstract
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.

19. An endoscope, comprising
an endoscope shaft, a mount for attaching an optical imaging device, and endoscope housing arranged between said endoscope shaft and said mount, an optical imaging arrangement disposed inside said endoscope housing and being at least partially positionally displaceable, an adjusting device for positionally displacing said optical imaging arrangement for focusing the image transmission, wherein said adjusting device has two outer ring elements, arranged around said outer side of said endoscope housing, that each carry at least one magnet, and two inner ring elements, arranged inside said endoscope housing, that also each carry at least one magnet, such that a rotary movement of said outer ring elements moves the respective associated inner ring element, and such that a rotation of said one outer ring element relative to said other outer ring element effects a positonal displacement of at least a portion of said optical imaging arrangement, and wherein said one outer ring element is joined nonrotatably to said mount, and said other outer ring element is rotatable relative to the latter, said mount being rotatable relative to said endoscope shaft via a rotary joint about a longitudinal axis of said endoscope, wherein said endoscope housing is configured in continuously hermetically sealed fashion and said rotary joint is arranged outside said endoscope housing and is configured at said mount.
