| 摘要 |
The invention relates to an endoscope, in particular for minimally invasive surgery, comprising a handpiece having a rigid tubular outer tube, in which at least one tubular working channel, a tubular flushing channel, and at least one tubular optical channel are formed. The channels are arranged asymmetrically inside the outer tube in such a way that a maximum illumination intensity is achieved in remaining free spaces of the outer tube by means of a light-conducting glass fiber bundle. |
