Embodiment 1

[0041] The structure of a kind of renal sympathetic radiofrequency ablation electrode described in this real-time example, such as figure 1 As shown, it includes a connecting pipe 3 , a first electrode 4 , a second electrode 5 , and an electrode connection line pipeline 11 . Wherein, the first electrode 4 and the second electrode 5 are fixed on the outer wall of the connecting pipe 3 , and the two electrodes are located on the same side of the connecting pipe 3 .

[0042] Such as figure 1 As shown, the electrode connecting wire pipeline 11 is arranged inside the connecting pipe 3 for connecting the first electrode lead and the second electrode lead to the radio frequency control device.

[0043] As other embodiments of the present invention, on the basis of the above embodiments, as figure 2 As shown, it also includes a first insulating holder 1 and a second insulating holder 2 arranged on the side wall of the connecting pipe 3, the first insulating holder 1 is used to fix ...

Embodiment 2

[0047] This embodiment makes the following improvements on the basis of embodiment 1, as Figure 4 As shown, the connecting pipe 3 also includes a physiological saline pipeline 101 suitable for the circulation of physiological saline, and the material of the physiological saline pipeline 101 is an electrically insulating and thermally insulating material. The first electrode 4 and the second electrode 5 are hollow structures. The physiological saline pipeline 101 has two branch pipelines, one of which passes through the hollow structure of the first insulating support 1 through the first electrode 4; the other branch pipeline passes through the second The insulating holder 2 passes through the hollow structure of the second electrode 5 .

[0048] The first electrode 4 and the second electrode 5 are hollow structures, and the hollow structures are connected to the two branch lines of the physiological saline line 101 through insulating brackets. The hollow structure of the fi...

Embodiment 3

[0051] Such as Figure 5 As shown, this embodiment makes the following improvements on the basis of Embodiment 1, the connecting pipe 3 also includes a coolant inflow pipeline 102 suitable for coolant circulation, a coolant circulation pipeline 104 and a coolant outflow pipeline 103 , the coolant inflow pipeline 102 communicates with one end of the coolant circulation pipeline 104 , and the other end of the coolant circulation pipeline 104 communicates with the coolant outflow pipeline 103 . The coolant described here is a coolant that cannot enter the human body and will cause harm to the human body.

[0052] The coolant circulation pipeline 104 is arranged between the first electrode 4 and the second electrode 5, and the coolant circulation pipeline 104 can adopt a gate-shaped pipeline as shown in the figure, respectively connected to the The outer wall between the first electrode 4 and the second electrode 5 is bonded.

[0053] When coolant is used to cool the radiofreque...

Abstract

The invention relates to a renal sympathetic nerve removing radiofrequency ablation electrode and system. The renal sympathetic nerve removing radiofrequency ablation electrode comprises a first electrode and a second electrode which are opposite in polarity. The two electrodes with the opposite polarities can effectively control the current flowing direction and range, and the radiofrequency ablation energy is concentrated, so that the renal sympathetic nerve on the outer wall of the renal artery blood vessel is burnt out accurately, unwanted injuries to organs and tissues outside the target treatment range are avoided, and the advantage of small destructiveness is achieved. Besides, as the radiofrequency ablation energy is concentrated, the renal sympathetic nerve on the outer wall of the renal artery blood vessel can be burnt out accurately and rapidly, the operating time is shortened greatly, and postoperative recovery of patients is facilitated.

Description

technical field [0001] The invention relates to a radiofrequency ablation electrode and a radiofrequency ablation system for treating hypertension, in particular to a radiofrequency ablation electrode and a radiofrequency ablation system for renal sympathetic nerve removal, and belongs to the technical field of radiofrequency ablation. Background technique [0002] Hypertension is one of the important diseases that threaten the health of all mankind. According to the China Cardiovascular Disease Report, there are more than 200 million adult hypertensive patients in my country, and 15-20% of them are resistant hypertension. Although the use of antihypertensive drugs has made staged progress in the treatment of hypertension, since the use of antihypertensive drugs cannot fundamentally cure hypertension, patients are highly dependent on antihypertensive drugs, and the patient's condition is extremely prone to repeatedly. In April 200, Krum et al. reported a new technique of pe...
