Abstract

Disclosed is a water-cooled radio frequency tumor extinguishing treatment system, which employs radio frequency heating means to place the target tissue in human body into between the melting electrode and leading electrode, a series resonant circuit is utilized in the radio frequency energy amplification, the rear portion of the melting electrode needle of the cold circulating pinshaped electrode is plated with an insulation coating layer, a bare tip is formed on the front end, thus the radio frequency energy capacity can radiate from around to the leading electrode, as a result, a melting zone is formed. The recirculated cooling water flows from the inlet pipe to the melting electrode needle, and returns to the recirculated cooling water subsystem from the exhaust pipe after heat interchange.

Description

technical field [0001] The invention relates to a water-cooled radio frequency tumor ablation treatment system, which is a radio frequency tumor ablation treatment system that applies radio frequency ablation technology and utilizes water cooling technology to increase and control the ablation range. It is applied to tumor treatment and belongs to the technical field of biomedical engineering . Background technique [0002] The radiofrequency tumor ablation treatment system based on radiofrequency in situ inactivation technology is a novel tumor surgical instrument, and it has become the most promising tumor treatment because of its characteristics of wide indications, minimal trauma, good curative effect, fast safety, convenience and easy operation. One of the means, since the late 1990s, has been one of research and development hotspots both at home and abroad. The existing radiofrequency tumor ablation treatment systems at home and abroad can basically be divided into tw...
