Self-stretching recording electrode, and preparation method and implantation method thereof

Abstract

The invention provides a self-stretching recording electrode. The self-stretching recording electrode comprises an adapter, a plurality of pin headers and a plurality of electrode wires, wherein the plurality of the pin headers are arranged on the adapter at intervals; the electrode wires comprise connecting sections and implantation sections; one ends of the connecting sections are connected withthe pin headers in a one-to-one correspondence manner; the other ends of the connecting sections are connected with one ends of the implantation sections; the connecting sections of the plurality ofthe electrode wires are coated through a protective glue; the parts, close to the connecting sections, of the implantation sections of the plurality of the electrode wires are bonded into a bundle through polyethylene glycol; and the parts, far away from the connecting sections, of the implantation sections of the plurality of the electrode wires are bonded into a bundle through a biodegradable glue. The self-stretching recording electrode provided by the invention has the following advantages: the size is small, and the electrical activity of a target brain area with a small area can be recorded; flexibility is good, and the biodegradable glue can be degraded in brain tissues; the flexibility degree of the electrode wires is recovered, and the electrode wires can move along with movementof the brain tissues, so damage to the brain tissues is reduced; and the structure is simple, and the cost is low. The invention also provides a preparation method and an implantation method for the self-stretching recording electrode.

Description

technical field [0001] The invention belongs to the technical field of electrodes, and in particular relates to a self-extending recording electrode, a preparation method and an implantation method thereof. Background technique [0002] The harm caused by brain diseases has always been underestimated. With the improvement of diagnostic technology and the advancement of social understanding, people have gradually discovered that brain diseases are a major hazard to human health, as well as the huge medical burden and social pressure brought by these diseases. With the advent of an aging society, the number of patients including Alzheimer's, Parkinson's, frontotemporal dementia and many other neurodegenerative diseases is rapidly increasing. Currently, neuropsychiatric diseases including schizophrenia, Parkinson's disease, depression, epilepsy, dementia, and drug addiction account for 13% of the total global incidence. According to data from the Center for Disease Control an...
