Radio frequency and chemical integrated ablation method

Abstract

The invention discloses a radio frequency and chemical integrated ablation method. A radio frequency and chemical integrated ablation device is utilized to perform ablation; the radio frequency and chemical integrated ablation method comprises the steps: putting a device, to be specific, putting a transfer catheter of the radio frequency and chemical integrated ablation device along a blood vesselof a patient, and making a radio frequency ablation electrode and injection head arranged at a distal end of the transfer catheter reach a lesion site which needs to be treated in a body; connectingfacilities, to be specific, connecting a proximal joint of the transfer catheter to a radio frequency ablation controller and a chemical ablation injector; implementing ablation, to be specific, performing radio frequency ablation and chemical ablation on the lesion site with the radio frequency ablation controller and the chemical ablation injector; and ending treatment, to be specific, after radio frequency ablation and chemical ablation end, removing the radio frequency ablation controller and the chemical ablation injector, and then, taking the transfer catheter out of the blood vessel ofthe patient to complete ablation. The radio frequency and chemical integrated ablation method can perform radio frequency ablation and chemical ablation simultaneously, and can also carry out radio frequency ablation and chemical ablation separately, so that improvement and promotion of the ablation effect are facilitated.

Description

technical field [0001] The invention relates to the medical field, in particular to a radio frequency and chemical integrated ablation method. Background technique [0002] Radiofrequency ablation is an interventional technique that sends a radiofrequency ablation catheter into a specific site through a blood vessel, and causes local nerve and tissue coagulation necrosis at a specific site by releasing radiofrequency current, so as to block the conduction beam or origin point. Because radiofrequency current has the advantages of small damage range and no harm to the body, it has been widely used in the treatment of arrhythmia, hypertension, diabetes and cancer tumors. [0003] Under the current technical conditions, the treatment effect of a single radiofrequency ablation is not ideal for some lesions with complex diseases, and further treatment by chemical ablation is often required. However, under the current conditions, these two ablation procedures need to be carried ou...

Problems solved by technology

[0004] The technical problem mainly solved by the present invention is to provide an integrated radiofrequency and chemical ablation method, which solves the problem that radiofrequency ablation and chemical ablation can only be carried out independently in the prior art due to the lack of an integrated ablation method
