Example Embodiment
[0038] The technical solutions of the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention.
[0039] Such as figure 1 , 2 As shown, a staggered array of bionic micro-textured brain stimulation cannula electrodes, the parameters of the cannula electrode's material, length, outer circle and inner hole diameter are the same as those of the clinically smooth cannula electrode; The bionic micro-texture with appropriate shape is processed on the cylindrical surface; the bionic micro-texture on the cylindrical surface of the sleeve electrode is a series of linear array grooves; the linear array grooves are in the circumferential direction of the cylindrical surface of the sleeve electrode There are 24 rows equidistantly distributed, and the linear array grooves in each row are equidistantly distributed along the direction of the cylindrical generatrix, and the circumferential distance of each row of linear grooves ...
