[0031] figure 1 b. figure 2 , image 3 , Figure 4 , Figure 5 An embodiment of the present invention is shown, in which there are 4 stimulation contacts 3, the metal wire is an 8-wire spiral wire, the sleeve has a groove and a capped electrode.
[0032] Such as figure 1 As shown in b, the main body of the electrode adopts a slender and flexible insulating sleeve. At least one metal ring is sleeved on one end of the sleeve as a stimulation contact. There are multiple metal spiral wires in the sleeve and pass through the stimulation contact. There are two The strands of metal wires are connected to the same stimulation contact and to the same connection point at the other end of the sleeve.
[0033] The flexible insulating sleeve of the electrode body is made of biocompatible organic polymer materials, such as silicone rubber and polyurethane materials. An annular groove is provided on the outer wall of one end of the flexible insulating sleeve for receiving stimulation contacts, ...
