Problems solved by technology
When the traditional ablation electrode eliminates the lesion, if the lesion is close to important blood vessels or nerves, the spherical ablation lesion of the traditional ablation electrode can easily damage the blood vessels or nerves close to the lesion
Therefore, traditional ablation electrodes still have the problems of low accuracy and poor ablation effect

The invention relates to a radio frequency ablation electrode. The radio frequency ablation electrode comprises an electrode head and an electrode body connected with the electrode head. The electrode body comprises an acting part and a connecting part connected with the acting part. The acting part is arranged between the electrode head and the connecting part. The acting part is partially covered with a first insulating layer. The portion, not covered with the first insulating layer, of the acting part is a radio frequency ablation part. The connecting part is completely covered with a second insulating part. According to the radio frequency ablation electrode, the radio frequency ablation part is arranged between the electrode head and the connecting part. The electrode body of the radio frequency ablation part is exposed and is not covered with the first insulating layer. The angle can be precisely positioned through the radio frequency ablation part formed on the radio frequency ablation electrode. When a doctor carries out radio frequency ablation treatment on tumors at the positions close to important blood vessels or nerves in visceral organs, additional damage can be avoided.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a radiofrequency ablation electrode and a radiofrequency ablation device. Background technique [0002] As a minimally invasive surgical method, radiofrequency ablation has achieved good therapeutic effects in the treatment of solid tumors in various organs and has been clinically recognized. Traditional ablation electrodes are 360-degree monopolar or multipolar electrodes. The ablation lesion formed during the application of traditional ablation electrodes is basically spherical or quasi-spherical. When the traditional ablation electrode eliminates the lesion, if the lesion is close to important blood vessels or nerves, the spherical ablation lesion of the traditional ablation electrode can easily damage the blood vessels or nerves close to the lesion. Therefore, traditional ablation electrodes still have the problems of low accuracy and poor ablation effect. Content...
