| 摘要 |
The invention relates to an endoscopic-surgery apparatus for argon-plasma coagulation (APC) to treat biological tissue. The surgery apparatus comprises a tube, a tubular probe or similar working device that can be inserted into an endoscope, with a first channel such that by way of the first channel, as a first working means, there can be guided to the tissue an electrode connected to an HF generator in order to generate a high-frequency current, as well as argon or a similar inert gas. This endoscopic-surgery apparatus is further developed in order to simplify endoscopic interventions employing argon-plasma coagulation, while simultaneously increasing the efficiency of a treatment. To this end, the working device comprises at least one second channel through which at least one second working means is guided to the tissue.
