Background
The nerve electrical stimulation has wide medical application, for example, can be used for treating nerve regeneration, muscular atrophy, overactive bladder, chronic pain and the like, and also has important practical significance in the field of traditional Chinese medicine.
Electrical nerve stimulation is generally divided into two categories, percutaneous non-invasive and implantable.
The percutaneous noninvasive electrode plate is directly attached to the skin surface of a human body through the electrode plate, and the operation is convenient. The conventional noninvasive electrode sheet type stimulation equipment has the advantage that an electrical stimulation host directly supplies stimulation electrical signals to the electrode sheet. However, when the stimulation waveform is transmitted to the nerve through the skin muscle, the waveform is already distorted, and the treatment effect is poor.
The stimulation electrodes are implanted surgically near the nerve. The stimulation waveform can be directly applied to the nerve, and the treatment effect is good. However, surgery brings about a large wound, has a long recovery period, is susceptible to infection, and also faces the problem of removal of the implant after the treatment is completed. As an implantable electrical stimulation patent: CN 112386795A.

Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
As shown in the overall structure diagram of the neuromuscular electrical stimulation calibration system shown in figure 1, the system comprises at least 2 probes 1, a calibration host 2 and at least 2 electrode plates 3 (two electrode plates form a stimulation current loop for output, and two probes form a loop for input monitoring signals). The method comprises the steps of applying a common electrode plate 3 to stimulate nerves to be attached to the surface of skin as required, enabling a probe 1 to penetrate into the skin under the guidance of imaging equipment (such as B-mode ultrasound, CT and the like), enabling the tip of the probe to be close to a target nerve, enabling a calibration host 2 to output an electrical stimulation signal to the electrode plate 3, enabling the calibration host 2 to simultaneously acquire a detection signal received by the probe 1, and enabling the calibration host to adjust the output stimulation signal at the electrode plate according to a feedback signal of the probe 1, so that the final stimulation signal at the probe is an expected signal.
As shown in FIG. 2, the probe structure comprises a probe tip 101, a hollow probe needle shaft 102 connecting the probe tip 101 and a probe handle 104, a probe wire 103 passing through the probe needle shaft 102 and the probe handle 104 and connecting the probe tip 101 and a probe connector 105, a probe handle 104 and a probe connector 105. The probe connector 105 is inserted directly into the calibration master 2, and the calibration master 2 receives signals detected by the probe tip 101.
The probe tip 101 is made of metal (preferably medical stainless steel), can detect an electric signal, is sharp in shape and can puncture the skin.
The probe pin 102, the cavity, the insulating material, or the metal pin with the insulating film or the insulating coating.
A probe handle 104 for operator control of the probe 101 to pierce the skin.
The probe connector 105 transmits 101 the probe tip signal to the calibration host 2 for analysis.
The noninvasive neurostimulation system performs stimulation through the electrode plate 3 on the skin surface (the stimulation signal is assumed to be A), but the signal finally transmitted to the nerve is distorted into B due to the impedance of skin muscles. The probe 101 is pre-embedded in the target nerve stimulation accessory to detect the signal B, feed back the signal B to the calibration host 2, and send the signal B to the electrode plate 3 after calibration, so that the target nerve stimulation signal is a required stimulation signal.
As shown in the structural block diagram of the calibration host in the neuromuscular electrical stimulation calibration system shown in fig. 3, the probe detection signal is sent to the signal processing circuit to process the acquired signal, remove clutter, then the waveform signal is sent to the main controller after being subjected to analog-to-digital conversion by the ADC, the main controller compares the waveform signal with the digital signal output to the electrode plate and the target digital signal, calculates the calibrated signal, and then the calibrated signal is output to the electrode plate after being subjected to digital-to-analog conversion by the DAC and then is sent to the electrode plate through the stimulation drive circuit, and finally the required stimulation effect is obtained.
The main controller is connected with a human-computer interaction interface, stimulation parameters can be set through the human-computer interaction interface, output waveforms and feedback waveforms are obtained, and various data in the stimulation process can be acquired.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
