Electrode lead for electro-hydraulic lithotripsy and electro-hydraulic lithotripsy device

The utility model relates to an electrode wire for electro-hydraulic lithotripsy and an electro-hydraulic lithotripsy device. The electrode wire for electro-hydraulic lithotripsy comprises: a first electrode having an extension direction; the insulator surrounds the first electrode, and the far end of the first electrode is exposed to the far end of the insulator in the extending direction; the second electrodes are located in the insulator and extend in the extending direction, the far ends of the second electrodes are exposed out of the far end of the insulator, and the at least two second electrodes are arranged at intervals. The electrode wire for electro-hydraulic lithotripsy can realize abundant discharge forms, and has higher structural strength. 本公开涉及一种液电碎石用电极导线及液电碎石装置。该液电碎石用电极导线包括：第一电极，具有延伸方向；绝缘体，绝缘体环绕包围第一电极，其中，沿延伸方向，第一电极的远端暴露于绝缘体的远端；以及至少两个第二电极，第二电极位于绝缘体中并沿延伸方向延伸，第二电极的远端暴露于绝缘体的远端，至少两个第二电极相互间隔设置。该液电碎石用电极导线可以实现丰富地放电形式，并且具有较高的结构强度。
