Radio frequency ablation system, ablation controller and radio frequency ablation device

Abstract

The invention discloses an RF ablation system, comprising an ablation controller and an RF ablation device. The ablation controller is used for generating RF energy, controlling the RF energy according to the set programs and conductance value of the ablation part acquired by the RF ablation device, generating excitation current according to the preset programs, receiving the results of measurement carried out by the RF ablation device by using the excitation current and judging whether ablation is successful or not; the RF ablation device is used for receiving the RF energy for RF ablation, sending the conductance value of the ablation part back to the ablation controller, carrying out conduction state measurement on the ablation part by the excitation current generated by the ablation controller and sending the measuring results back to the ablation controller. The operation process is simplified as the operations of taking out the ablation clamps and putting in the pacing leads areunnecessary, thereby reducing the operation time, lowering the operation difficulty, increasing the operation safety and providing better operation effects.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a radio frequency ablation system, an ablation controller and a radio frequency ablation device. Background technique [0002] Atrial fibrillation is a common cardiac arrhythmia. Atrial fibrillation is caused by excessive abnormal electrical signals received by the atrium, causing the atrial beat to be significantly faster and extremely irregular. Atrial fibrillation affects the pumping function of the heart, which means that the brain and other organs of the body do not get enough blood supply. Over time, atrial fibrillation can cause a decline in cardiac function, causing irreversible cardiac damage. When atrial fibrillation causes insufficient pumping function of the heart, some blood will pool in the heart to form a blood pool, which becomes viscous and forms a thrombus. If part of the clot breaks off, it may cause a stroke. In fact, untreated patients with atrial fibrillat...

Problems solved by technology

Because it is necessary to repeatedly remove the ablation forceps, put in the pacing lead, and then put in the ablation forceps, the operation is complicated, the operation is dangerous and difficult.

On the other hand, since most of the existing radiofrequency ablation forceps adopt the scissors-type closing method, the closing force is uneven, and the contact pressure with the ablated tissue is uneven during ablation, resulting in uneven tissue ablation

In addition, the existing ablation forceps need to be manually pressed and maintained, and the pressure cannot be effectively controlled for tissues of different thicknesses, which may easily cause incomplete ablation or excessive burning, causing tissue charring
