Embedded neural signal recording device and method of use thereof

Abstract

The invention relates to the technical field of neural signal recording devices, and discloses an embedded type neural signal recording device and a method for applying the same. The embedded type neural signal recording device comprises a connecting portion, a neural insulating protective sleeve, a horizontal first electrode and a horizontal second electrode. The neural insulating protective sleeve is fixedly mounted on the right of the connecting portion, an opening in the front-back direction is axially formed in the upper portion of the neural insulating protective sleeve, and a subcutaneous fixation hole in the vertical direction is formed in the connecting portion. The embedded type neural signal recording device and the method have the advantages that the problem of increase of artifact due to unstable contact between nerve trunks, an existing first electrode and an existing second electrode can be solved, the labor intensity can be greatly relieved for experimenters, and problems that the nerve trunks are passively lengthened, are violently injured, are exposed in the air for a long time, are quickly dried and are cooled, the activity of the nerve trunks is lowered, nerves can die and experiments fail can be solved; the embedded type neural signal recording device and the method are safe and reliable, operation can be facilitated, and the success rate can be increased.

Description

technical field

[0001] The invention relates to the technical field of nerve signal recording devices, and relates to an embedded nerve signal recording device and a method for using the same. Background technique

[0002] At present, the recording of nerve trunk signals in animal experiments requires the experimenter to separate the nerve trunks, and then pick out the nerve trunks from the animal with a pen-type nerve signal electrode to record nerve signals in vitro. This device has three disadvantages: 1. The experimenter holds a pen-type nerve signal electrode, which causes the recording signal artifacts to increase and the interference to increase due to poor contact between the electrode and the nerve signal; Exposure to the outside of the body for a long time will lead to the rapid drying of the nerve trunk exposed to the air and the decrease in temperature, resulting in a decrease in nerve activity and even death of the nerve, and the experiment fails; Structural vi...

Embodiment 1

[0022] Embodiment 1, as attached figure 1 As shown, the embedded nerve signal recording device includes a connection part 1, a nerve insulating protective cover 2, a first electrode 3 and a second electrode 4 in the horizontal direction; the nerve insulating protective cover 2 is fixedly installed on the right part of the connecting part 1, An opening 5 in the front and rear direction is arranged axially on the upper part of the nerve insulating protective sheath 2, and a subcutaneous fixing hole 6 in the vertical direction is arranged in the connection part 1, and first electrodes 3 are respectively fixedly installed at intervals in the middle part of the connection part 1. and the second electrode 4 , the right ends of the first electrode 3 and the second electrode 4 are respectively located in the nerve insulation protective sheath 2 . In this way, the nerve insulation protective sheath 2 can well insulate the nerve trunk from surrounding tissues after being inserted into t...

Embodiment 2

[0029] Embodiment 2, as attached figure 1 As shown, the use method of the embedded nerve signal recording device is carried out according to the following steps: the first step, the experimental animal is anesthetized, and after the skin preparation of the operation area, the skin is cut, and the nerve trunk to be recorded is separated and exposed; The first step is to open the opening 5 on the nerve insulating protective sheath 2, and insert the separated nerve trunk into the nerve insulating protective sheath 2 through the opening 5 on the nerve insulating protective sheath 2, so that the first electrode 3 and the second electrode 4 are in close contact with each other. On the nerve trunk; in the third step, a line is passed through the subcutaneous fixing hole 6 of the connection part 1, and the two ends of the line are respectively bypassed by the connection part 1 and the nerve insulation protection sheath 2 and tied to make the nerve insulation protection sheath The open...
