Abstract

The invention relates to a method and a device for pressure regulation and fixation of an epidural microstimulation (EMS) visual cortex neural prosthesis. The device consists of a pressure regulation plate, pressure regulation screws and a three-dimensional locating rack, wherein the pressure regulation plate can realize an interface between a microelectrode array chip and endocranium in a bone window; the pressure between a microelectrode array chip and an implanted endocranium region can be finely regulated through the pressure regulation screws; and the horizontal distance of a support and a shift port is regulated by a beam of the three-dimensional locating rack to improve effective transfer of a neuroelectricity stimulation signal in the endocranium and other nervous tissues and effectiveness of signal record. The device can effectively fix the EMS visual cortex neural prosthesis and effectively regulate the pressure between the microelectrode array chip and the endocranium, thereby ensuring accuracy, reality and stability of a microelectrode array chip stimulation signal and voltage signal record.

Description

technical field [0001] The invention relates to a technique for pressure regulation and fixation of a cortical nerve prosthesis. Background technique [0002] Impaired nerve function will bring great pain to patients, and it is currently difficult to cure most of the nervous system injuries with biological methods. With the rapid development of microelectronics technology and related fields of neurobiology, a new interdisciplinary research field has emerged, that is, using the function of surviving neurons after damage to neural pathways, and implanting electrodes and functional integrated circuits to complete biological research. The function of information acquisition, processing and regeneration stimulation, so as to achieve the purpose of repairing and rebuilding the nervous system function. The ultimate goal of nerve function restoration is to develop a system-on-a-chip that is fully integrated or hybrid-integrated with nerve microelectrodes and function restoration in...
