Repairing device and method for stimulating nerves by near infrared light

Abstract

The invention discloses a repairing device and a repairing method for stimulating nerves by near infrared light. An optical fiber is connected with a laser, and near infrared laser generated by the laser is transmitted onto nervous tissue to be repaired; a microelectrode array is inserted in the nervous tissue to be repaired, and is connected with a multichannel acquisition instrument through an electrode adapter and a leading wire; the multichannel acquisition instrument is connected with a computer through a transmission cable; the multichannel acquisition instrument carries out amplification; wave filtering and digitalized treatment on induced potential acquired by the microelectrode array, and the induced potential is treated, displayed and stored through the computer; the included angle between the optical fiber long axis of the optical fiber and the axis of recording a microelectrode is 0 to 45 degrees; and the wave length of the near infrared light generated by the laser is in the range of 780-2526nm. Through the device and the method disclosed by the invention, the nervous tissue can be efficiently activated so as to induce nerve impulse and realize the repairing of neurological function, and the device is relatively short in artifact time interval, relatively high in resolution factor and is not contacted with the nervous tissue directly.

Description

technical field [0001] The invention belongs to a device and method for repairing nerve function, in particular to a repair device and method for stimulating nerves with near-infrared light. Background technique [0002] Impaired nerve function will bring great suffering to patients, and it is currently difficult to use biological methods to cure most nervous system injuries. From the perspective of nerve function information transmission pathways, nerve function repair can be carried out at the levels of receptors, afferent nerves, nerve centers, efferent nerves, and effectors. The cerebral cortex is the most advanced nerve center, and it is the neural prosthesis method with the best nerve repair effect. The stimulation methods include electrical stimulation, magnetic stimulation and light stimulation. [0003] With the improvement of science and technology and clinical level, nerve electrical stimulation restoration has become a research hotspot for a while, which mainly ...

AI Technical Summary

Problems solved by technology

[0004] (1) There are artifacts in the electrical stimulation method, which need to be oscillated in the interstitial fluid to disappear, and it takes a long time;

[0005] (2) Since the size of the microelectrode is limited by the processing technology, and the microelectrode will be soaked and corroded in the interstitial fluid, the improvement of the electrical stimulation resolution will be limited by the microelectrode array;
