[0025] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0026] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and appropriate controllers and encoders should be selected according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principles and processes, and no longer explains the electrical control.

[0027] Medical ultrasound imaging uses the propagation characteristics of ultrasound in human tissues to perform imaging. Ultrasound is a sound wave with a frequency higher than 20kHz, which is emitted by an ultrasound probe (transducer). When ultrasound encounters the tissue interface inside the human body, due to the difference in acoustic impedance (the resistance encountered by sound waves when propagating in the medium) between different tissues, part of the sound wave will be reflected back to form echoes. These echoes are received by the probe and converted into electrical signals, which are processed to form images on the display.

The stimulation structure and the injection structure are arranged on the stimulation needle body 1, and the stimulation structure comprises: a front ultrasonic reflection wave point 2, a middle ultrasonic reflection wave point 3, an upper ultrasonic reflection wave point 4, a pair of pulse stimulation connectors 5, a pair of wires 6, a half-set metal needle 7 and an auxiliary buckle block 8;

[0030] Specifically, the stimulation needle body 1 is movably inserted into the inner side of the half-set metal needle 7, the front ultrasonic reflection wave point 2 and the middle ultrasonic reflection wave point 3 are arranged on the stimulation needle body 1, the upper ultrasonic reflection wave point 4 is arranged on the half-set metal needle 7, a pair of wires 6 are respectively installed on the half-set metal needle 7 and the stimulation needle body 1, and a pair of pulse stimulation connectors 5 are respectively installed on the pair of wires 6; a pair of movable buckle grooves 16 are opened on the stimulation needle body 1, and the auxiliary buckle block 8 is installed on the half-set metal needle 7. The auxiliary buckle block 8 is U-shaped, and the auxiliary buckle block 8 can be movably inserted into the movable buckle groove 16. The two long sides of the auxiliary buckle block 8 are loose. Through the thin and long characteristics of the auxiliary buckle block 8, the auxiliary buckle block 8 can be partially stretched, and through the metal elastic deformation of the auxiliary buckle block 8, the auxiliary buckle block 8 can be inserted into the inner side of the movable buckle groove 16; the stimulation needle body 1 and the half-set metal needle 7 are provided with an insulating coating 14;

[0031] It should be noted that the stimulation needle body 1 is inserted into the patient's body, connected to the current device through the pulse stimulation connector 5, and the current is drained to the stimulation needle body 1. Similarly, the current is drained to the half-set metal needle 7. The insulating coating 14 makes the exterior of the stimulation needle body 1 and the half-set metal needle 7 non-conductive, and the needle tip part does not have the insulating coating 14 and can conduct electricity. The insulating coating 14 is 0.5CM away from the stimulation needle body 1 and the needle tip of the half-set metal needle 7. The signal is echoed and displayed through the front ultrasonic reflection wave point 2 and the middle ultrasonic reflection wave point 3 on the stimulation needle body 1, making the echo display image more obvious.

[0032] When the location of the nerve that the patient needs to stimulate is not deep, first pull out the auxiliary stretching buckle block 8 so that the two long sides of the auxiliary buckle block 8 are no longer inserted into the inner side of the movable buckle groove 16 for limiting, and pull out the stimulation needle body 1 along the inner side of the half-set metal needle 7, insert it into the patient through the half-set metal needle 7, and echo display the signal through the upper ultrasonic reflection wave point 4 on the half-set metal needle 7 to make the echo display image more obvious.

[0034] Specifically, the inclined drug injection tube 9 is obliquely inserted into the tail end of the stimulating needle body 1, the hollow drug administration tube 10 is connected to the tap 11, and the hollow drug administration tube 10 is movably inserted into the inner side of the stimulating needle body 1; the half-sheath metal needle 7 is provided with a stretch buckle 12, and the stretch buckle 12 is provided with a stretch protective sleeve 13, and the stretch protective sleeve 13 can be movably sheathed on the stimulating needle body 1; the inclined drug injection tube 9 is provided with a one-way valve 17; the outer side of the half-sheath metal needle 7 is provided with a plastic sheath tube 15, and the half-sheath metal needle 7 and the stimulating needle body 1 are provided with scales and a level gauge;

[0035] It should be noted that the drug solution is drained to the inner side of the hollow drug delivery tube 10 through the branch joint 11. When long-term drug delivery is required, the hollow drug delivery tube 10 is inserted into the inner side of the stimulation needle body 1, and the stimulation needle body 1 and the half-set metal needle 7 are withdrawn, so that the hollow drug delivery tube 10 remains inside the patient's body for drug delivery; the stimulation needle body 1 and the half-set metal needle 7 are protected by stretching the buckle 12 and the protective cover 13 on the half-set metal needle 7, and the stimulation needle body 1 and the half-set metal needle 7 are wrapped by stretching the protective cover 13; when the distance between the patient's nerve and the skin is close, the half-set metal needle 7 is inserted into the patient's body, and when long-term drug delivery is required, the half-set metal needle 7 is withdrawn by stretching the half-set metal needle 7, and the plastic sheath tube 15 outside the half-set metal needle 7 remains inside the patient's body for drug delivery; the scales on the stimulation needle body 1 and the half-set metal needle 7 allow the doctor to adjust the insertion depth according to the treatment needs; the angle of the half-set metal needle 7 and the stimulation needle body 1 is adjusted by a level.
