| 摘要 |
The ablation system (10) according to the invention works with an ablation probe (12, 12a) that comprises two alternatingly working spark plasma electrodes (31, 32). They generate a plasma beam (47, 48) having a non-circular cross-section, which beam is to be guided—transversely with respect to the large longitudinal axis of its preferably oval cross-section—over the tissue to be ablated, in particular the mucosa (14). In doing so, it is possible to treat large-area tissue regions by means of a reliable and easily controllable procedure. |

1. Ablation system (10), in particular for large-area mucosal ablation, comprising:
a plasma ablation probe (12, 12a) comprising at least two similar spark plasma electrodes (31, 32) that are arranged adjacent to each other, a single electrical power source (38) for high frequency (HF) voltage and two electrical lines (33, 34) that are parallel to each other leading to the spark plasma electrodes (31, 32), a switch arrangement (40) arranged between the source (38) and the two electrical lines (33, 34) to alternatingly connect the lines (33, 34) to the source (38), a gas source (53) and at least one fluid line (20) leading from the gas source (53) to the similar spark plasma electrodes (31, 32). |
