Embodiment 1
[0041] The structure of a radiofrequency ablation electrode for renal sympathetic nerve described in this embodiment is as follows: 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...
