Multichannel radio frequency ablation system and control method

Abstract

The invention discloses a multi-channel radio frequency ablation system and a control method. The multi-channel radio frequency ablation system comprises a plurality of ablation electrodes, an audio module, a power generator module, a temperature measuring module, a channel output control module, a touch control module of a key knob module, a respiration monitoring system and a main control unit.The ablation electrodes are connected the channel output control module, and the audio module, the power generator module, the temperature measuring module, the channel output control module, the touch control module of the key knob module and the respiration monitoring system are connected with the main control unit. The invention realizes that several ablation electrodes simultaneously act on one tumor ablation, and the radio frequency signals between the electrodes do not interact with each other, thus realizing once ablation of large tumor, and the maximum ablation is 6-7cm tumors.

Description

technical field [0001] The invention relates to a multi-channel radiofrequency ablation system and a control method. Background technique [0002] The single-needle ablation technique is mostly used in the market. The range of single-needle ablation is limited. Generally, a single needle can only ablate tumors below 3 cm. Tightly arrange multiple needles according to a certain layout for ablation. This ablation method is to superimpose and ablate multiple needles in a simple and rough way. During the ablation process, the interaction of radio frequency signals between electrodes makes the ablation effect And efficiency is greatly reduced. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a multi-channel radio frequency ablation system and a control method. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: [0005] A...
