Abstract

The invention relates to the technical field of medical radio-frequency ablation, and in particular to an interelectrode discharge ablation device. The interelectrode discharge ablation device comprises an ablation catheter and a guide tube, wherein an ablation handle is arranged on a guide handle in a sliding mode; the ablation catheter comprises a catheter body; at least two conductive parts are arranged at the end 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 a closed loop is defined; the catheter body comprises a solution cavity; 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 , stress on the ablation catheter can be monitored in an ablation process in real time, and an ablation area can be increased; with the application of an electrical stimulation method, a focus tissue can be searched; and meanwhile, operations can be facilitated.

Description

technical field [0001] The invention relates to the technical field of medical radiofrequency ablation, in particular to an interelectrode discharge 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 rub against each other and collide with other particles to genera...
