Problems solved by technology

However, each electrode segment constituting the main body of its work has a special shape and is difficult to process; special plastic forming materials are used, so the price is expensive
In addition, it is automatically destroyed within 12 hours after the start of treatment, and can only be used once, which brings a heavy economic burden to patients and greatly limits its scope of use.

Abstract

A RF electrode for treating atrial fibrillation is composed of a silica rubber tube, a plastic rod in said silica rubber tube, a plastic handle, PCB fixed to the handle, a RF head and 7 RF tubes on said silica rubber tube at intervals, RF connectors between two adjacent RF tubes, and two temp-measuring thermocouples.

Description

technical field [0001] The invention relates to a radiofrequency ablation electrode for treating atrial fibrillation, which is applied in radiofrequency ablation maze operation to treat atrial fibrillation (AF) and restore sinus rhythm, and belongs to the technical field of biomedical engineering. Background technique [0002] The radiofrequency ablation electrode for the treatment of atrial fibrillation is one of the key components of the atrial fibrillation radiofrequency ablation treatment instrument. Under open chest and direct vision, it follows the maze operation line, uses the radiofrequency ablation effect to cause tissue coagulation necrosis, and effectively blocks the cause and maintenance of atrial fibrillation. Fibrillation reentry loop, thereby eliminating atrial fibrillation. [0003] At present, only the radiofrequency ablation electrodes produced by Boston Scientific EP technologies for the treatment of atrial fibrillation (matched with the company's product ...
