Radiofrequency ablation equipment

Abstract

The invention provides radiofrequency ablation equipment which comprises a direct current boost module, a conversion module, an alternating current boost module, a detection module and a control module. The direct current boost module boosts first direct current voltage input by the outside to form second direct current voltage. The conversion module is electrically connected with the direct current boost module, receives the second direct current voltage output by the direct current boost module and converts the second direct current voltage into alternating current voltage with target frequency. The alternating current boost module is electrically connected with the conversion module and boosts the alternating current voltage output by the conversion module. The detection module is electrically connected with the alternating current boost module and detects the output voltage and the output current of the alternating current boost module. The control module is electrically connected with both the detection module and the direct current boost module, receives the output voltage and the output current, detected by the detection module, of the alternating current boost module to obtain output power and controls the direct current boost module to boost or lower the second direct current voltage according to the obtained output power.

Description

【Technical field】 [0001] The invention relates to a medical device, and in particular to a radio frequency ablation device capable of releasing radio frequency current to cause local cell necrosis so as to achieve the purpose of ablation or hemostasis. 【Background technique】 [0002] At present, the main method for the treatment of liver tumors is still liver resection. Due to the complex distribution of blood vessels and rich blood supply in the liver, previous liver resections were always accompanied by massive bleeding and high mortality. With the in-depth study of liver anatomy, the improvement of surgical techniques, surgical management and advances in anesthesia, hepatectomy has become relatively safe. However, surgical resection of tumors in special parts of the liver, especially for patients with liver cirrhosis, may still cause fatal bleeding during the operation, and blood transfusion may increase the incidence of postoperative complications and mortality, even a ...
