Electrode lead, stimulator and medical system

The invention provides an electrode wire, a stimulator and a medical system. The electrode wire comprises a catheter, a contact, a wire electrically connected with the contact, and a contact extension mechanism. The contact extending mechanism is arranged on the guide pipe, and at least part of the contacts are arranged on the contact extending mechanism. Through the arrangement of the contact extension mechanism, the position of the contact can be flexibly adjusted after the electrode wire is implanted and fixed in the body of a patient, and the electrical stimulation effect and the LFP collection effect can be improved. 本申请提供电极导线、刺激器以及医疗系统，所述电极导线包括导管、触点、与所述触点电连接的导线、以及触点延伸机构；所述触点延伸机构设置于所述导管上，至少部分所述触点设置于所述触点延伸机构。通过设置触点延伸机构，在电极导线被植入固定在患者体内后，触点的位置可以灵活调节，可以提升电刺激效果和LFP采集效果。
