Abstract

The invention discloses an ablation adsorption electrode which comprises a hollow tube and a connector, wherein the tail portion of the hollow tube extends into the connector, is connected with a negative pressure adsorption system through a negative pressure adsorption system port and is connected with an ablation instrument through a lead wire. The head portion of the hollow tube is sharp, blade-shaped or serrated, and the negative pressure adsorption system is a vacuum pump or a negative pressure aspirator. The ablation adsorption electrode can effectively act on a targeted organization and avoids influence of liquid on ablation electrodes. The ablation electrodes are tightly contacted with an action organization so that the ablation electrodes can act deep. Contact between the ablation electrodes and blood is reduced so that sludged blood is not apt to generate, treatment cannot be affected, harm to human bodies caused by sludged blood is avoided, and ablation treatment effect is good.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to an ablation adsorption electrode. Background technique [0002] Ablation therapy has become a hot spot both at home and abroad. Electromagnetic waves generated by generators such as microwave and radio frequency act on the treatment site through ablation electrodes. Ablation therapy is mainly used in cardiovascular medicine, tumor surgery, ENT, orthopedics and other medical fields. [0003] The current ablation electrodes are mainly solid electrodes, which are used for the treatment of removing solid tumors, herniated intervertebral discs, and nerve blocks. When the existing ablation electrodes act on bleeding blood vessels, hemangiomas or tissues with local fluid, fluid or blood will ooze out from the ablation site, and the body surface is generally removed with a cotton swab. [0004] In the process of realizing the present invention, the inventors found that the prior art has ...
