Abstract
The utility model provides a Z-shaped double-electrode renal artery sympathetic nerve radiofrequency ablation catheter. The Z-shaped double-electrode renal artery sympathetic nerve radiofrequency ablation catheter mainly comprises a sleeve, an operating handle which is connected with the tail end of the sleeve, and two electrodes which are arranged at the front end of the sleeve, wherein the two electrodes are in Z-shaped connected with each other, and serve as a far-end electrode and a near-end electrode respectively; the far-end electrode is positioned at the far end of the Z shape, and the near-end electrode is positioned at the far end of the other branch of the Z shape; and the two electrodes have a separation distance. The two electrodes of the Z-shaped double-electrode renal artery sympathetic nerve radiofrequency ablation catheter are axially arranged to ensure that electrode ablation is not on a transverse plane and not in a longitudinal axial direction, so that spiral non-closed-loop ablation injuries are conveniently generated to the renal artery.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of renal artery radio-frequency ablation electrode.
Background technology
Hypertension is a kind of common clinical illness, though and a part of patient through the treatment of the multiple antihypertensive drugs of associating, but still can not reach the purpose of effective controlling blood pressure.At present, for this part refractory hypertension, can adopt and melt renal artery and reach blocking-up kidney orthosympathetic effect, thereby reach the purpose of treatment refractory hypertension.
Mostly ablation catheter commonly used at present is common radio-frequency ablation electrode conduit, and pointwise is moved and moved the conduit discharge along all footpaths of renal artery along the renal artery major axis and melts, and reaches the non-closed loop of helical form and melts renal artery.This method does not have clear and definite localization method, and need 4-6 time mobile conduit with melt complicated operation, and the location is difficult to accurately be difficult to reach ideal effect.
The utility model content
The purpose of this utility model, be to provide a kind of more simply, renal artery ablation catheter accurately.Isolate the kidney sympathetic nerve to reach, the purpose of treatment refractory hypertension.
This utility model the provides bipolar renal artery sympathetic nerve of a kind of " Z " font RF ablation conduit, mainly by a sleeve pipe, the operating grip that is connected with the sleeve pipe tail end; And the electrode of sleeve pipe front end composition, it is characterized in that: said electrode is respectively remote electrode and proximal electrode for being in two electrodes that " Z " font connects; Wherein remote electrode is positioned at " Z " font far-end; Proximal electrode is positioned at another far-end of " Z " font, between two electrodes spacing is arranged, and two electrodes are and are arranged in parallel.
Preferred scheme is that remote electrode and proximal electrode are vertical at a distance of 1.0cm.
Preferred scheme is that remote electrode and proximal electrode laterally are 0.8cm apart.
The length that preferred scheme is remote electrode and proximal electrode is 3mm, and diameter is 2mm.
Preferred scheme is provided with two little interfaces of electrode tail end for operating grip inside, connects through electrode cable respectively to link to each other with proximal electrode with remote electrode.
Adopt above technical scheme, two electrodes of this utility model are according to parallel axially-aligned, make electrode ablation not a transverse plane and longitudinal axis on, be beneficial to renal artery is produced the ablation lesions of the non-closed loop of helical form.
Description of drawings
Fig. 1 is the structural representation of this utility model;
The specific embodiment
Below in conjunction with the Fig. 1 and the specific embodiment, this utility model is done further detailed explanation, but this specific embodiment and be not used in the protection domain that limits this utility model.
This utility model is the bipolar renal artery sympathetic nerve of a kind of " Z " font RF ablation conduit, mainly by a sleeve pipe, and the operating grip 1 that is connected with the sleeve pipe tail end; And the electrode of sleeve pipe front end composition, it is characterized in that: said electrode is respectively remote electrode 3 and proximal electrode 2 for being in two electrodes that " Z " font connects; Wherein remote electrode 3 is positioned at " Z " font far-end, and proximal electrode 2 is positioned at another far-end of " Z " font, between two electrodes spacing is arranged; Two electrodes are and are arranged in parallel, and remote electrode 3 and proximal electrode 2 be vertically at a distance of 1.0cm, and remote electrode 3 and proximal electrode 2 are laterally at a distance of being 0.8cm; The length of remote electrode 3 and proximal electrode 2 is 3mm; Diameter is 2mm, and operating grip 1 inside is provided with two little interfaces of electrode tail end, connects through electrode cable respectively to link to each other with proximal electrode with remote electrode.
Adopt above-mentioned technology when renal artery melts, the ablation lesions of generation at a distance of 1.0cm, and differs 180 ° on the ring renal artery, therefore neither can cause vertically damage continuously, also can not produce transverse annular and damage continuously.
This utility model behind femoral artery puncture, through femoral artery sheath pipe, is sent into Arterial system under the guiding of X line when concrete the use, get into renal artery then.After remote electrode reached the renal artery far-end, under X line perspective, the operation conduit made " Z " font electrode be uprightly " Z " word arrangement, provides radio frequency through two electrodes respectively then.Return then and remove conduit 0.5cm, the operation conduit is formed on " Z " word and becomes " one " font to arrange on the floor projection, provides radio frequency through connecting an electrode catheter respectively then.After this operation, the damage everywhere that renal artery produces is distributed in the 1.5cm length, and vertically is distributed on the different warps along major axis.
Above content is to combine structure and the work process of this utility model to its further explain of doing, and can not assert that the practical implementation of this utility model is confined to these explanations.For the those of ordinary skill of technical field under this utility model, under the prerequisite that does not break away from this utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of this utility model.
