Abstract

The invention discloses a flexible multi-channel deep brain stimulation three-dimension electrode based on the micromachining technology, which comprises a planar flexible film electrode and a special die, wherein the planar flexible film electrode is positioned right in the middle of the special die. With adoption of the technical scheme of the invention, the problem about accurate control on deep brain stimulation and multi-channel electrode size is solved, the flexible multi-channel deep brain stimulation three-dimension electrode has the characteristics of convenience in machining and accurate in electrode distribution, and can integrate the flexible circuit technology to realize control on multiple simulation or recording points by utilizing fewer external connected leads.

Description

technical field [0001] The invention relates to a flexible multi-channel deep brain stimulation three-dimensional electrode based on micro-processing technology. Background technique [0002] Deep brain stimulation refers to the electrical stimulation (deep brain stimulation, DBS) of specific parts of the brain tissue, so as to achieve the purpose of treating or relieving nerve-related diseases. It has been successfully applied to Parkinson's, epilepsy, tremor and other central nervous system diseases relief and treatment. Electrodes are used to transmit electrical pulses to the specific functional nuclei of the brain by stimulating the electrodes to stimulate the area to achieve the purpose of treating related diseases. [0003] However, because the functional nucleus area is often relatively small, for example, the hypothalamic nucleus related to the treatment of Parkinson's disease, its size is spherical with a diameter of 3-4 mm or egg-shaped with a diameter of 3-4 mm a...
