Embodiment Construction

[0025] 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.

[0026] Such as Figure 1-4 As shown, a linear staggered array bionic micro-textured deep 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; A biomimetic microtexture with a suitable shape is processed on the cylindrical surface of the tube electrode; the appearance of the bionic microtexture on the cylindrical surface of the sleeve electrode is a series of linear array grooves; the linear array grooves on the cylindrical surface of the sleeve electrode 24 columns are equidistantly distributed in the circumferential direction, and each column of linear array grooves is equidistantly distributed along the direction of the generatrix of the...

Abstract

The invention aims to reduce puncture friction force between the cylindrical surface of a bushing electrode and brain tissue in a deep brain stimulation operation and lower the degree of puncture injury of the bushing electrode to brain tissue, and provides a bushing electrode with linear staggered array bionic micro-textures and for deep brain stimulation based on the idea of friction reduction of bionic micro-textures on a friction surface. According to the invention, a series of linear array groove bionic micro-textures are machined on the cylindrical surface of the bushing electrode; the linear array grooves are equidistantly distributed in 24 columns in the circumferential direction of the cylindrical surface of the bushing electrode; the total length of a bionic micro-texture area is59.5 mm, the heads of the linear grooves at the two ends of the bionic micro-texture area are aligned, the distance between the bionic micro-texture area and a puncture end face is 0.5 mm, and adjacent columns of the linear grooves are distributed in a staggered mode and can assist each other in supporting the wrapping effect of brain tissue on the cylindrical surface; and the widths of all the linear grooves are 18 microns, and the depths of all the linear grooves are 10 microns. Thus, the puncture friction force between the cylindrical surface of the bushing electrode and the brain tissue can be reduced, and the degree of puncture injury of the bushing electrode to the brain tissue is reduced.

Description

technical field [0001] The invention belongs to the technical field of deep brain puncture intervention, and in particular relates to a linear staggered array bionic micro-textured deep brain stimulation sleeve electrode. Background technique [0002] With the growth of human age and the increase of life and work pressure, some neural nuclei in the deep part of the brain will become dysfunctional, which will lead to a series of mental activity disorders such as behavior, will, cognition, emotion and other diseases, which seriously threaten Harmful to human physical and mental health. Deep brain stimulation is an effective way to treat these conditions. However, the implementation of deep brain stimulation is relatively complicated, and a combination of stereotaxic and microelectrode recording techniques is required to implement the positioning of the stimulating electrodes to the target. Among them, the microelectrode recording process needs to use the cannula electrode wi...
