[0025] specific implementation plan
[0026] refer to figure 1 , 2 , 3, taking four metal leads 1 as an example. The internal metal lead is formed by winding the metal lead 1 on the core wire 3 to form a multi-headed spiral. The metal lead 1 is made of stainless steel or platinum-iridium alloy wire or high-elastic alloy wire with an insulating layer. The material of the insulating layer is fluoropolymer, polyurethane or silicone rubber. The diameter of the metal lead 1 is about 0.075-0.2mm (including the insulating layer) , the bare wire diameter of the internal metal lead is 0.05-0.15mm, and has good blood compatibility and tissue compatibility. The core wire 3 is made of stainless steel wire, tungsten wire or memory alloy wire, and has good rigidity, with a diameter of 0.30-1.2mm. 1 number of metal leads and the final image 3 Corresponds to the number of electrodes wound in the center.

Abstract
The present invention discloses an implanted bioelectrode used to treat diseases such as parkinsonism. A metal lead is tightly wound on the surface of an insulating tube to form a spiral electrode ring framework, which replaces the traditional metal tube as an electrode framework; a biocompatible metal is then plated on the tightly wound metal lead in order to increase the thickness of the electrode;the metal lead is plated into the integral tubular electrode in order to be fixed on the insulating tube; and finally, the electrode is plated with biocompatible oxide for the second time, so that the biocompatibility and adhesive force between the surface of the electrode and the surrounding nervous nuclei can be increased. The method can avoid the welding between the traditional cerebral electrode tube and the internal wire, thus avoiding welding from burning the insulating tube and oxidating the electrode tube.
Description
technical field [0001] The invention relates to a biological electrode, in particular to an implanted biological electrode. Background technique [0002] Stimulating nerve nuclei by implanting electrode discharge can effectively treat many major human diseases. Currently, the implanted bioelectrodes used in clinical practice mainly use mechanically processed metal tubes as the discharge terminals of the electrodes. This kind of mechanically processed metal electrode tube not only needs to complete the electrode package through the mold, but the cost is high and the process is complicated, and it needs to be connected with the lead wire by welding, which is easy to cause ablation of the surrounding sealing insulating tube material and oxidation of the electrode tube itself. Injection into the human body is likely to cause corrosion of the electrode tube and failure of the electrode insulation. The failure of the electrode brings not only the interruption of treatment but also...
