Abstract

The invention discloses a surface-roughened random bionic micro-texture deep brain stimulation cannula electrode, the cylindrical outer surface of the cannula electrode is provided with a bionic micro-texture, the bionic micro-texture is composed of a series of pits, the shapes and sizes of the pits are randomly generated, the positions, located on the cannula electrode, of the pits are randomly generated, and the positions, located on the cannula electrode, of the pits are randomly generated. The pits are blind holes with irregular shapes, the pits are randomly and mutually overlapped, and the mutually overlapped pits are communicated to form a capillary tube. The cannula electrode has the advantages that the cannula electrode is provided with the random bionic microtexture with the roughened surface, the original guiding function of the cannula electrode is not affected, cerebrospinal fluid can be stored, the effective friction area between the cannula electrode and brain tissue is reduced, puncture friction force is reduced, and the deformation degree of the brain tissue in the puncture process can be reduced; and pit microstructures formed by surface texturing are randomly and mutually overlapped and communicated to form a capillary tube, a lubricant is more easily captured by utilizing the capillary tube effect, and puncture injury of the cannula electrode to brain tissues is reduced.

Description

Technical field [0001] The present invention belongs to the field of cerebral stimulation puncture in the field, and in particular, the present invention relates to a surface-mounted random bionic micro-wear brain deep stimulation sleeve electrode. Background technique [0002] With the exacerbations of population aging and human life, the increase in work pressure, more and more patients present the deep disease in the brain, leading to certain neuronal dysfunction of the brain, showing a series of behaviors, will, recognition Psychiatric disorders such as knowing, emotions, seriously hurting human body and mental health. [0003] The brain depth stimulation is an effective way to treat such a disease. During the operation, the casing electrode will perform a long path to the brain tissue to achieve the positioning of the tip of the stimulus electrode to the target, the length of the puncture path is generally greater than 50 mm. When the tube electrode is pierced into the brain...
