Abstract

The present application discloses a radio frequency ablation instrument, comprising: an ablation parameter detection unit for collecting current ablation parameters in real time; a radio frequency output unit; and a main processor respectively connected to the ablation parameter detection unit and the radio frequency output unit, The main processor includes: a power calculation module, used to calculate the power value that the radio frequency output unit needs to output in the next cycle according to the current ablation parameters; a voltage acquisition module, used to obtain the output power value according to the required output an input control voltage corresponding to the power value; and a radio frequency output control module, configured to control the radio frequency output unit to output radio frequency energy according to the input control voltage. Therefore, the output accuracy and continuous output stability of the radiofrequency ablation instrument can be improved, and even when the output is disturbed, the stability of the radiofrequency ablation instrument can reach a certain degree of stability, effectively ensuring the ablation effect.

Description

technical field [0001] This application relates to a radiofrequency ablation instrument. Background technique [0002] Radiofrequency ablation technology is widely used in the medical field. Radiofrequency ablation apparatus is a kind of medical equipment using this technology. Radiofrequency ablation apparatus generates and regulates radiofrequency energy and uses radiofrequency energy to ablate tissue to achieve the purpose of curing patients. Its specific The working process is: put the ablation electrode of the radiofrequency ablation instrument into the site to be ablated in the patient's body, and put the neutral electrode in contact with the patient's skin surface, so that the radiofrequency current can flow through the ablation electrode and the patient's tissue, and form a circuit with the neutral electrode After the circuit loop is formed, due to the small area of ​​the ablation electrode and the high electric field strength, it will produce an obvious thermal effe...
