The technology of spiral needle electrodes

Technical features:
The present invention relates to the field of medical device technology and specifically discloses a medical disposable spiral needle electrode, comprising an electrode plug, a wire, a spiral needle, and a handle. The spiral needle is connected to the electrode plug through a wire, and a conical handle is provided on the spiral needle. The advantage of the present invention is that a new type of needle electrode is formed by using a spiral needle and a conical handle, which is easy to operate, reliable, and improves the accuracy of signal acquisition. The disposable electrode can avoid cross infection caused by repeated use, which is conducive to the recovery of the patient's condition, resulting in low cost, simple operation by doctors, and accurate signal acquisition.
