23 Jul And deep brain stimulation electrode can be used for detecting blood oxygen level of deep brain nuclei
Abstract
The utility model relates to the field of biomedical engineering, in particular to a deep brain stimulation electrode capable of detecting the blood oxygen level of deep brain nuclei, which comprisesa ring electrode, a core electrode arranged along the axis of the ring electrode, an insulating layer arranged between the ring electrode and the core electrode, a sleeve arranged outside the ring electrode, and an optical fiber arranged between the ring electrode and the sleeve, the ring electrode is flush with the output end of the optical fiber, and the output end of the core electrode extendsout of the output end of the ring electrode. According to the technical scheme of the utility model, the core electrode and the ring electrode pair are used for stimulating electrodes. The optical fiber used for optical signal transmission and acquisition is ingeniously arranged into a whole; isolation and insulation are realized through the insulating layer. Therefore, at the cost of invasiveness, the capacity of synchronously observing and recording the local blood oxygen saturation degree change of the deep brain nuclei during deep brain electrical stimulation of the deep brain nuclei of rodents is obtained, and the device can be used as a low-cost brain tissue metabolic activity in-vivo research tool and meets the brain science research requirements of general research institutions onbrain blood oxygen metabolism and the like.
