Endoscopic instrument, has shaft and video unit provided at distal end of shaft, where video unit is spaced apart from distal end along axial direction, and is movable along viewing direction relative to distal end

摘要

The instrument has a shaft (2) and a video unit (8) provided at a distal end (6) of the shaft. The video unit is spaced apart from the distal end along an axial direction (X), and is movable along a viewing direction relative to the distal end. A video sensor is provided in the video unit along another viewing direction (10). An image detour element is placed in an optical path upstream to the video sensor. A drive is fixed within the video unit or the shaft for moving the video unit along the axial direction.
