[0006] Preferably, an embedding groove is provided on the outer wall of the nerve cannula body, and the embedding groove is an annular groove. The edges of two parallel annular surfaces of the embedding groove are provided with arc-shaped slopes. The laser-printed flexible electrode sleeve is arranged inside the embedding groove, and the outer diameter of the laser-printed flexible electrode is smaller than the tube diameter of the nerve cannula body.

[0007] Preferably, the cleaning ring is a convex circular tube structure, and the outer ring surface of the cleaning ring is provided with a scraping groove, which is an annular groove.

[0008] Preferably, an installation groove 1 is provided on the inner ring surface of the notch at one end of the cleaning ring. The installation groove 1 is an annular groove. Two installation grooves 1 are provided. The two installation grooves 1 are located on both sides of the notch at one end of the cleaning ring. A rubber scraper ring is fixed on the surface of the installation groove 1. The rubber scraper ring is a circular ring plate with an isosceles trapezoidal cross-section. The inner ring diameter of the rubber scraper ring is smaller than the tube diameter of the nerve cannula body.

[0009] Preferably, a second mounting groove is provided at the notch at the other end of the cleaning ring. The second mounting groove is an annular groove. A wiping cotton ring is fixed on the surface of the second mounting groove. The wiping cotton ring is an annular plate structure. The inner ring diameter of the wiping cotton ring is smaller than the tube diameter of the nerve cannula body. The wiping cotton ring is clamped between the second mounting groove and the nerve cannula body to produce elastic deformation.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The embedded flexible electrode neural cannula proposed in the utility model can realize fast and accurate printing by laser printing technology, which greatly simplifies the production process and improves production efficiency. At the same time, it reduces manual operation and reduces production costs; due to the use of laser printing technology, there is no need to insert the electrode wire into the cannula, thus avoiding the risk of contamination caused by manual operation and reducing the possibility of harm to the patient; the use of flexible circuit boards as electrodes can better fit the surface of the neural tissue and improve the accuracy and stability of signal acquisition.
