Embodiment Construction
[0038] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0039] Such as figure 1 , 2 As shown, a staggered array bionic micro-textured brain stimulation cannula electrode, the parameters of the cannula electrode, such as material, length, outer circle and inner hole diameter, are the same as those of the clinically smooth surface cannula electrode; the cannula electrode A bionic micro-texture with a suitable shape is processed on the cylindrical surface; the appearance of 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. 24 columns are equidistantly distributed on the top, and each column of linear array grooves is equidistantly distributed along the direction of the generatrix of...
