Abstract

The invention relates to the technical field of medical radio-frequency ablation, and in particular to an interelectrode discharge ablation catheter, an ablation device and a using method of the ablation device. The interelectrode discharge ablation catheter comprises a catheter body; at least two conductive parts are arranged at the end, stretching into a human body, of the catheter body; radio-frequency current, which is applied to the conductive parts, sequentially passes through one of the conductive parts, human tissues and the other conductive part, so that at least one closed loop is defined; the catheter body comprises a solution cavity for transmitting ablation liquid; and a solution hole, which communicates with the solution cavity, is formed in the at least one conductive part, so that ablation liquid can be transmitted to the to-be-ablated human tissues by virtue of the solution cavity and the solution hole; therefore, an ablation area can be increased; and with the application of an electrical stimulation method, a focus tissue can be searched.

Description

technical field [0001] The invention relates to the technical field of medical radiofrequency ablation, in particular to an interelectrode discharge ablation catheter, an ablation device, and a method for using the ablation device. Background technique [0002] The human body is a complex structure composed of many organic and inorganic substances. The body fluid contains a large number of dielectrics, such as ions, water, colloidal particles, etc. The human body mainly relies on the movement of ions to conduct current. Under the action of high-frequency alternating current, the ion concentration change direction changes back and forth with the current direction as positive and negative half cycles. Under high-frequency oscillation, the ions between the two electrodes move rapidly along the direction of the electric force line, gradually changing from a moving state to a vibrating state. Due to the different sizes, masses, charges and moving speeds of various ions, the ions...
