Document Type and Number:
WIPO Patent Application WO2002087426
Kind Code:
A3
Abstract:
The invention relates to an optical instrument (10), particularly an endoscope (12), which comprises a shaft (14) and an exchangeable head (26). The exchangeable head (26) is detachably connected to the distal end (19) of the shaft (14) at a coupling location (30). The instrument (10) also comprises a first transmission system for transmitting illuminance power toward the distal end and a second transmission system for transmitting image information toward the proximal end, whereby the first transmission system and the second transmission system pass through the coupling location (30). The exchangeable head (26) and/or the coupling location (30) are/is configured in order to transmit an item of image information, which is modified in a qualitatively perceivable manner, via the second transmission system when the exchangeable head (26) becomes loose. The second transmission system can be provided in the form of an image recorder, which is placed inside the exchangeable head, and has an electrical signal line.
