Embodiment 1

[0048] Embodiment 1: as figure 1 As shown, the present invention provides a single-bipolar radiofrequency ablation system capable of delivering stimulation, including:

[0049] The control circuit 1 is used to issue control commands to control the work of the radio frequency generating circuit 2 and the signal processing circuit 5;

[0050] The radio frequency generating circuit 2 is used to generate a specified frequency radio frequency signal according to the command; in this embodiment, such as figure 2 The structure of the radio frequency generation circuit 2 shown, of course, any other radio frequency generation circuit 2 that can be applied to this field can also be used; in this embodiment, the radio frequency generation circuit 2 includes a control signal isolation transmission controller, a radio frequency Power amplifier driving circuit, radio frequency power amplifier circuit, isolation transformer, radio frequency output circuit; wherein, the input end of the con...

Embodiment 2

[0063] Embodiment 2: The difference from Embodiment 1 is that in this embodiment, the unipolar and bipolar radiofrequency ablation system capable of delivering stimuli is also provided with a foot pedal switch and a liquid crystal touch screen, and the foot pedal switch is connected to the controller. The user controls the sending and stopping of the radio frequency signal through the foot pedal switch. And this liquid crystal touch screen is connected with controller, is used for human-computer interaction, and the button in described touch is provided with button horn, thereby when the user carries out key operation through described touch screen, there is sound prompt; An alarm sound can be issued when an abnormality occurs in the system or operation.

Abstract

The invention relates to the field of radiofrequency medical devices, and especially relates to a monopolar and bipolar radiofrequency ablation system capable of generating stimulation. The monopolarand bipolar radiofrequency ablation system capable of generating stimulation integrates the stimulation function with the radiofrequency function to overcome a defect that existing heart radiofrequency devices needs the stimulation function, but cannot integrates in the same device in order to make a doctor switch two functions and achieve easy use. The system also can measure the bioelectrical conduction of a measuring machine in the refractory period, and effectively improves the anti-interference ability of an ECG signal by a signal processing circuit.

Description

technical field [0001] The invention relates to the field of radiofrequency medical equipment, in particular to a single-bipolar radiofrequency ablation system capable of delivering stimulation. Background technique [0002] Radiofrequency refers to the non-modulated sine wave with a frequency between 300KHz and 1000KHz. The radiofrequency ablation device emits radiofrequency through the radiofrequency catheter to act on specific parts of the body for ablation and blockage to achieve therapeutic effects. Currently, radiofrequency ablation systems can treat many diseases. [0003] In monopolar RF, one electrode is the working electrode and the other uses the back plate as the return electrode. The electrode surface of monopolar radio frequency can concentrate high energy, and the emitted energy can penetrate deeper. However, since the electrode and the back plate form a loop, the loop and location through which the current flows cannot be controlled. In bipolar RF, the cur...
