Endoscope in particular with electrically operated components, comprising inner shaft at maximal distance to outer shaft

摘要

The device can be an endoscope (1) fitted with a video camera and the related components (9, 10) and is inserted into a natural or specifically created duct (2) in the body of the patient (3). The inner pipe (8) containing a video chip (9), an amplifier (13), and some wires (14), is insulated against the outer shaft (4) with ceramic rings (21). The current level guided still into the body of the patient (3) is reduced by designing the inner unit (8) in a particular narrow shape compared to the outer shaft (4) and increasing the distance between them.
