Embodiment 1

[0049] This embodiment will give the implementation of setting a group of radio frequency electrodes on the catheter, please refer to figure 2, is a schematic diagram of a structural principle of setting a group of radio frequency electrodes on the catheter. As shown in the figure, the catheter 210 is cylindrical in shape, and each group of radio frequency electrodes 220 may include multiple pairs of first radio frequency electrode units 221 and second radio frequency electrodes unit 222, the number of the first radio frequency electrode unit 221 and the second radio frequency electrode unit 222 is the same, and each first radio frequency electrode unit 221 and second radio frequency electrode unit 222 are arranged parallel to the axial direction on the cylindrical catheter 210, and each A radio-frequency electrode unit 221 and a second radio-frequency electrode unit 222 are alternately arranged on the cylindrical catheter 210, that is, each first radio-frequency electrode uni...

Embodiment 2

[0054] The first radio frequency electrode unit 221 and the second radio frequency electrode unit 222 included in each group of radio frequency electrodes 220 in the first embodiment above are radio frequency electrodes with a linear structure. See image 3 , is a schematic diagram of another structural principle of setting a group of radio frequency electrodes on the catheter, as shown in the figure, the difference from the above-mentioned embodiment 1 is that each first radio frequency electrode unit 221 and the second radio frequency electrode unit included in the radio frequency electrode 222 is attached on the side of the cylindrical catheter 210 in the circumferential direction, and each of the first radio frequency electrode unit 221 and the second radio frequency electrode unit 222 forms a ring-shaped radio frequency electrode. Other structures are consistent with the above-mentioned embodiments. A multi-faceted treatment area can be formed through this structure, and...

Embodiment 3

[0062] See Figure 4 , is a schematic diagram of another structural principle of setting a group of radio-frequency electrodes on the catheter, as shown in the figure, the difference between this embodiment and the above-mentioned embodiments 1 and 2 is that each first radio-frequency electrode unit 221 and The second radio frequency electrode units 222 are alternately arranged on the side of the cylindrical catheter 210 along the circumferential direction. This structure can ensure that the heating on different cross-sections in the axial direction is basically consistent, ensuring the uniformity of treatment.

[0063] In general, the above-mentioned embodiments 1-3 have provided the situation that a group of radio frequency electrodes 220 are arranged on the catheter 210, and provided the first radio frequency electrode unit 221 and the second radio frequency electrode unit 222 in the group of radio frequency electrodes 220 With various implementation structures and preferr...

Abstract

The invention provides a radio-frequency electrode treatment catheter and a radio-frequency electrode treatment device. The radio-frequency electrode treatment catheter comprises a catheter and at least one group of radio-frequency electrodes, wherein one or more groups of radio-frequency electrodes are arranged on the catheter, each group of radio-frequency electrodes comprises a plurality of first radio-frequency electrode units and second radio-frequency electrode units corresponding to each other, each of the first radio-frequency electrode units and the second radio-frequency electrode units is alternately arranged on the surface of the catheter at intervals along at least one direction, and radio-frequency power supplies applied by the first radio-frequency electrode units and the second radio-frequency electrode units are opposite in polarity. The treatment catheter for treating vascular diseases is improved, the electric conduction situation between different radio-frequency electrodes is avoided, a better curative effect can be achieved in the vascular disease treatment process, the treatment duration is prolonged by virtue of ingenious interval, and then the convenience in treatment is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a radio frequency electrode treatment catheter and a radio frequency electrode treatment device based on radio frequency technology. Background technique [0002] At present, there are more and more applications of radio frequency therapy using radio frequency technology. For example, in the treatment of vascular diseases, especially in the treatment of varicose veins, radio frequency treatment equipment can be used for treatment. The radiofrequency treatment is similar to the optical fiber, and the treatment of the entire blood vessel is realized by adding a radiofrequency emission device to the top of the hose and moving the hose successively. [0003] For example, see figure 1 , is a schematic diagram of the principle of using radio frequency electrodes to treat vascular diseases in the prior art. As shown in the figure, the radio frequency electrode 10 is composed of a radio...
