Abstract

In order to reduce the puncture friction between the surface of a cannula electrode cylinder and brain tissue in deep brain stimulation surgery and decrease the puncture damage degrees of the cannulaelectrode on the brain tissue, and through the combination of the antifriction thought of a bionic microtexture on friction surfaces, a staggered array bionic microtexture brain stimulation cannula electrode and a preparation method thereof are provided. A series of linear type array groove bionic microtextures is processed on the surface of the cannula electrode cylinder; the linear type array groove bionic microtextures are equidistantly distributed in the circumferential direction on the surface of the cannula electrode cylinder; through a solid nanosecond laser system, a hollow rotary clamping device with controllable rotating speed and rotating angles and an angle tilt table with controllable inclination degrees, linear type grooves can be processed on the outer cylinder of the cannula electrode in the processing form of laser scanning, so that processing can be automatically and efficiently accomplished, and the dimensional precision of the grooves can be guaranteed; and the prepared cannula electrode can reduce the puncture friction between the surface of the cannula electrode cylinder and the brain tissue and decrease the puncture damage degrees of the cannula electrode onthe brain tissue.

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 and a preparation method thereof. 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 need...
