Embodiment 1

[0072] The electrode assembly provided in this embodiment is as follows Figure 1 to Figure 8 Electrode assembly shown.

[0073] In this embodiment, the support member 413 is a pipe body.

[0074] The pulling wire assembly 420 includes a first pulling wire 421 , a second pulling wire 422 and a third pulling wire 423 . The first pulling wire 421 , the second pulling wire 422 and the third pulling wire 423 are all connected to one end of the electrode terminal 410 .

[0075] The second pulling wire 422 is located between the first pulling wire 421 and the third pulling wire 423, and the center line of the second pulling wire 422 coincides with the center line of the support member 413, so that when the second pulling wire 422 is pulled, the electrode tip 410 is in a straightened position At this time, neither the first pull wire 421 nor the third pull wire 423 can be pulled.

[0076] The first pulling wire 421 and the third pulling wire 423 are located on two sides of the cent...

Embodiment 2

[0114] The electrode assembly provided in this embodiment is as follows Figure 9 to Figure 11 Electrode assembly shown.

[0115] In this embodiment, the pulling wire assembly 420 includes a fourth pulling wire 424, the fourth pulling wire 424 is disposed in the lumen of the support member 413, and the center line of the fourth pulling wire 424 is deviated from the center line of the supporting member 413, so as to pull the fourth pulling wire At 424, the electrode tip 410 is bent or in a straightened state.

[0116] In this embodiment, the electrode tip further includes a magnetic member 412 , the electrode 411 and the magnetic member 412 are both annular or D-shaped structures, and the electrode 411 and the magnetic member 412 are sleeved on the support member 413 .

[0117] In some embodiments, there are at least two electrode tips 410 .

[0118]Optionally, there are multiple magnetic members 412 , multiple electrodes 411 and multiple magnetic members 412 are sleeved on t...

Embodiment 3

[0122] The present invention also provides an ablation device, the ablation device includes a first electrode 111 assembly and a second electrode 112 assembly, the first electrode 111 assembly is the electrode assembly in the first embodiment, and the second electrode 112 assembly is in the second embodiment. The electrode assembly of the first electrode 111 assembly is opposite to the electrode 411 of the second electrode 112 assembly, so that the electrode 411 of the first electrode 111 assembly and the electrode 411 of the second electrode 112 assembly are located in the first electrode 111 assembly. The tissue to be ablated between the electrode 411 of the second electrode 112 and the electrode 411 of the second electrode 112 assembly is ablated.

[0123] Specifically, the ablation device further includes an ablation circuit, and the electrodes 411 of the first electrode 111 assembly and the electrodes 411 of the second electrode 112 assembly are both disposed on the ablati...

Abstract

The invention provides an electrode assembly, an ablation device and radiofrequency ablation equipment, the electrode assembly comprises an electrode tip and a stay wire assembly, the electrode tip comprises a support piece and a plurality of electrodes arranged on the support piece, the support piece is strip-shaped, and the plurality of electrodes are arranged at intervals along the extension direction of the support piece; the pull wire assembly is connected with the electrode end head, so that the electrode end head is bent or in a straightened state by pulling the pull wire assembly, the electrode end head can form a good fitting effect with to-be-ablated tissues, and then each electrode can better act on the corresponding to-be-ablated tissues so as to ensure the ablation effect; therefore, by using the electrode assembly, the problem that the ablation effect of an ablation device in the prior art is not ideal can be solved.

Description

technical field [0001] The present invention relates to the field of medical devices, in particular, to an electrode assembly, an ablation device and a radiofrequency ablation device. Background technique [0002] Ablation is a common measure for the treatment of atrial fibrillation. The principle is to create one or more ablation lines in the heart tissue, causing tissue necrosis and cutting off abnormal electrical signal conduction for the treatment of atrial fibrillation. [0003] The current ablation treatment is divided into surgical ablation and medical interventional ablation. Surgical ablation is characterized by excellent curative effect and low postoperative recurrence rate, but its obvious shortcomings are large trauma and slow postoperative recovery. Medical interventional ablation is favored by more and more patients because of its small trauma and fast recovery, but medical ablation is point ablation, and its biggest drawback is that it is difficult to form a c...
