ABLATION SYSTEM FOR THE LARGE-SCALE SURFACE COAGULATION OF BIOLOGICAL TISSUES

摘要

The ablation system (10) according to the invention uses an ablation probe (12, 12a) which has two alternating spark plasma electrodes (31, 32). A plasma jet (47, 48) with a non-circular cross-section is produced by these, which is to be guided transversely to the large longitudinal axis of its preferably oval cross-section over tissue to be ablated, in particular via the mucosa (14). This allows large-area tissue areas to be processed reliably and with good control.
