Title
(EN) Ablation catheter
(ZH) 消融导管
Abstract
(EN) The utility model provides an ablation catheter which comprises a handle and a bearing rod connected to the far end of the handle. The bearing rod comprises a mapping ring and an ablation ring which are arranged at the far end, and the ablation ring is located between the mapping ring and the handle. The mapping ring and the ablation ring are annular and extend around the axis of the bearing rod. A mapping electrode is arranged on the mapping ring, an ablation electrode is arranged on the ablation ring, the ablation electrode is used for transmitting ablation energy to a target tissue area, and the mapping electrode is used for transmitting an electrophysiological signal in the target tissue area to the handle. According to the ablation catheter, the ablation ring and the mapping ring are integrated, so that the ablation catheter can have the functions of detecting the electrophysiological signal of the target tissue and ablating the target tissue at the same time, the surgical operation is more convenient, and the success rate of the surgical operation is improved.
(ZH) 本实用新型提供了一种消融导管,包括手柄以及连接于所述手柄远端的承载杆。所述承载杆包括设置于远端的标测环和消融环,且所述消融环位于所述标测环和所述手柄之间。所述标测环与所述消融环均呈环形,并围绕所述承载杆的轴线延伸。所述标测环上设置有标测电极,所述消融环上设置有消融电极,所述消融电极用于向目标组织区域传递消融能量,所述标测电极用于将目标组织区域中的电生理信号传输至所述手柄。本申请消融导管将所述消融环和所述标测环集成于一体,使得所述消融导管能同时具备对目标组织的电生理信号进行检测,以及对目标组织进行消融的功能,使得手术操作更加便捷,有利于提高手术的成功率。
