УСТРОЙСТВО ДЛЯ ХОЛОДОВОЙ РАДИОЧАСТОТНОЙ АБЛЯЦИИ

摘要

FIELD: medical equipment. ^ SUBSTANCE: device can be used for local ablation at surgical treatment. Device for cold part of radio-frequency ablation has high frequency current source connected to bipolar electrode, which electrode is disposed in electro-conducting fluid in cooling unit. Device also has measuring current electrode connected in series with measuring current capacitive component detector, comparison unit and signaling unit and threshold meanings set-point device. Output of set-point device is connected with other input of comparison unit. The other input measuring unit capacitive component detector is connected with measuring input of high frequency current source. Measuring current electrode is made for mounting onto surface of biologic object close to or around operation area. Optimal results of local cold radio frequency ablation can be achieved due to provision of signalization during withdrawal of bipolar electrode out of borders of admissible interval of distance to surface of operation area. ^ EFFECT: optimal results of ablation. ^ 1 dwg
