Abstract

The invention relates to a medical apparatus, in particular to a radiofrequency ablation volume reduction electrode capable of leading out waste gas in the liver. The radiofrequency ablation volume reduction electrode comprises a radiofrequency electrode tip, a temperature measurement resistor and a liver waste gas draw-out assembly. The radiofrequency electrode tip is connected with a radiofrequency transmission hole arranged in an outer pipe to give out a radiofrequency current, and is used for conducting radiofrequency ablation on lesion tissue of alveolus pulmonis. The temperature measurement resistor is connected with a temperature measurement resistor cable and used for collecting the temperature of an ablation area and regulating the temperature released by a radiofrequency electrode. The liver waste gas draw-out assembly comprises a gas draw-out hole and a gas draw-out passageway connected with the gas draw-out hole, and is used for drawing out waste gas in the liver. The radiofrequency ablation volume reduction electrode can conduct radiofrequency ablation treatment on the lesion tissue of the alveolus pulmonis and can meanwhile draw out a large amount of gas detained in the alveolus pulmonis which loses the function, and therefore the aims of reducing the volume of the liver and treating pulmonary emphysema are achieved.

Description

technical field [0001] The invention relates to a medical device, in particular to a radiofrequency ablation electrode, especially a radiofrequency ablation volume reduction electrode capable of leading out exhaust gas from the lungs. Background technique [0002] Emphysema is a common chronic obstructive pulmonary disease. In the late 1990s, a new method for the treatment of emphysema—lung volume reduction—was developed abroad, and achieved good results. Practice has proved that the symptoms, exercise capacity, and lung function indicators of most patients can be significantly improved, and the curative effect can last for more than 3-4 years. [0003] The modified lung volume reduction surgery (LVRS), which began in 1995, has opened up a new way for the treatment of emphysema. Recent large-sample randomized studies have confirmed that LVRS resection of overinflated non-functioning lung tissue can prolong the survival time and improve the quality of life of patients.
