Implantable miniature LED neurological probe

Abstract

The invention relates to an implantable miniature LED neurological probe. The probe comprises a probe body, a probe head is arranged at the front end of the probe body, and the rear end of the probe body is provided with a connection end. The probe body comprises a miniature LED array, a driving circuit and probe pins. The miniature LED array comprises x*y LED elements. Each LED element corresponds to one driving unit, and the x*y driving units form the driving circuit. The LED elements are electrically connected with the driving units and located at the probe head at the front end of the probe body. Electrodes of the driving units are connected with the probe pins, each driving unit corresponds to one probe pin, and the x*y probe pins are distributed side by side and located at the connection end of the rear end of the probe body. Ultra-high resolution of the neurological probe and multi-area multi-angle stimulation and monitoring of brain nerve cells can be achieved. Interconnection of the miniature LED array and Parylene C flexible polymer can be achieved through the electric interconnection method, affinity of the probe to human bodies is enhanced, and harm caused when rigid objects exert too much pressure on brain tissue is avoided.

Description

technical field [0001] The present invention relates to a kind of neurological diagnosis and treatment equipment, more specifically, it provides an implantable micro-LED nerve probe for monitoring brain nerve activity, which is a tool that helps medical personnel find a cure for nervous system diseases . Background technique [0002] Neural probes have had a dramatic effect on our understanding of the brain by revealing the workings of biological neuronal networks. Neural probes are currently used in the medical field mainly for brain diseases such as epilepsy, migraine, Alzheimer's, dementia and other neurological diseases. In recent years, under the background of the continuous development and improvement of microelectronics technology and optogenetics, the research of neural probes has also achieved rapid progress and development. By implanting neural probes in different areas of the brain to record and stimulate specific sites in the brain, it is possible to detect, pr...

Problems solved by technology

[0003] However, the current neural probes lack a high-resolution identification of the propagation and imaging of light sources in brain tissue, and their current use is limited to acute studies due to the absence of available light sources for chronic experimental studies.

Although in some studies it has been possible to transmit light into the brain by using fiber optics and tiny endoscopes, these solutions are very harmful to the brain because they make rigid objects exert too much traction on the brain tissue , thus limiting their use in acute experiments, so the study of neural probes still needs to be continuously improved and improved to a large extent
