Radio frequency ablation electrode for treating atria fibrillation

Abstract

A radio frequency ablation electrode for treating atrial fibrillation. A radio frequency head cover and seven radio frequency solenoids in an acting body are tightly sheathed outside a silicone rubber tube at equal intervals, and the radio frequency head cover and each radio frequency solenoid have built-in radio frequency joints and two temperature measuring tubes. The thermocouple is fixed between the silicone rubber tube and the RF head cover or RF solenoid by virtue of the tension of the silicone rubber tube, the plastically formed rod is built into the center of the silicone rubber tube, and all the RF leads and the thermocouple leads are passed through the silicone rubber tube and stainless steel The branch pipe leads out and connects to the printed circuit board fastened to the plastic handle. The present invention has a novel and compact structure, and the main body can be artificially shaped according to the labyrinth operation route correctly and conveniently. The radio frequency headgear and radio frequency coils involved in the actual ablation can be flexibly selected according to the needs in a continuous or discontinuous arrangement, and a maximum of eight segments can be arranged at the same time. The two temperature measuring thermocouples in each segment provide two sets of real-time temperature data for the atrial fibrillation radiofrequency ablation therapy instrument at the same time, and the work is safe and reliable.

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 ...

AI Technical Summary

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.
