[0025] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0027] Medical ultrasound imaging utilizes the propagation characteristics of ultrasound waves within human tissues to create images. Ultrasound waves are sound waves with frequencies higher than 20 kHz, emitted by an ultrasound probe (transducer). When ultrasound waves encounter the interfaces of tissues within the human body, due to differences in acoustic impedance (the resistance encountered by sound waves as they propagate through a medium) between different tissues, some of the sound waves are reflected back, forming echoes. These echoes are received by the probe and converted into electrical signals, which are then processed to form an image on a display screen.

[0028] Example

[0029] like Figure 1-5 As shown, a disposable indwelling nerve stimulation needle includes: a stimulation needle body 1, a stimulation structure, and a drug injection structure. The stimulation structure and the drug injection structure are disposed on the stimulation needle body 1. The stimulation structure includes: anterior ultrasound reflection point 2, middle ultrasound reflection point 3, upper ultrasound reflection point 4, a pair of pulse stimulation connectors 5, a pair of leads 6, a half-set of metal needles 7, and an auxiliary locking 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 ultrasound reflection point 2 and the middle ultrasound reflection point 3 are set on the stimulation needle body 1, and the upper ultrasound reflection point 4 is set 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 locking slots 16 are opened on the stimulation needle body 1. An auxiliary locking block 8 is installed on the half-set metal needle 7. The auxiliary locking block 8 is U-shaped and can be movably inserted into the movable locking slot 16. The two long sides of the auxiliary locking block 8 are loose. Due to the thin and long characteristics of the auxiliary locking block 8, part of the auxiliary locking block 8 can be stretched. Due to the elastic deformation of the metal of the auxiliary locking block 8, the auxiliary locking block 8 can be inserted into the inner side of the movable locking slot 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, and the current device is connected through the pulse stimulation connector 5 to guide the current to the stimulation needle body 1. Similarly, the current is guided to the half-metal needle 7. The external parts of the stimulation needle body 1 and the half-metal needle 7 are non-conductive through the insulating coating 14. The needle tip does not have the insulating coating 14 and can conduct electricity. The insulating coating 14 is 0.5 cm away from the needle tip of the stimulation needle body 1 and the half-metal needle 7. The signal is displayed by the front ultrasound reflection point 2 and the middle ultrasound reflection point 3 on the stimulation needle body 1, making the echo display image clearer.

[0032] When the nerve location to be stimulated 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 limitation. Then pull out the stimulation needle body 1 along the inner side of the half-set metal needle 7 and insert it into the patient through the half-set metal needle 7. The signal is displayed by the upper ultrasound reflection point 4 on the half-set metal needle 7, making the echo display image clearer.

[0033] like Figure 1-5 As shown, the drug injection structure includes: an inclined drug injection tube 9, a hollow drug delivery tube 10, and a connector 11;

[0034] Specifically, the inclined injection tube 9 is obliquely inserted into the tail end of the stimulation needle body 1, the hollow drug delivery tube 10 is connected to the connector 11, and the hollow drug delivery tube 10 is movably inserted into the inner side of the stimulation needle body 1; the half-metal needle 7 is provided with a tension buckle 12, the tension buckle 12 is provided with a tension protective sleeve 13, and the tension protective sleeve 13 can be movably fitted onto the stimulation needle body 1; the inclined injection tube 9 is provided with a one-way valve 17; the outer side of the half-metal needle 7 is provided with a plastic sleeve tube 15, and the half-metal needle 7 and the stimulation needle body 1 are provided with a scale and a level.

[0035] It should be noted that the medication is diverted to the inside of the hollow administration tube 10 via the tap 11. When prolonged administration is required, the hollow administration tube 10 is inserted into the inside of the stimulating needle body 1, and the stimulating needle body 1 and the half-metal needle 7 are withdrawn, leaving the hollow administration tube 10 inside the patient's body for administration. The stimulating needle body 1 and the half-metal needle 7 are protected by the stretching buckle 12 and the stretching protective sleeve 13 on the half-metal needle 7. The stretching protective sleeve 13 wraps around the stimulating needle body 1 and the half-metal needle 7. When the distance between the patient's nerve and skin is close, the half-metal needle 7 is inserted into the patient's body. When prolonged administration is required, the half-metal needle 7 is withdrawn by stretching, leaving the plastic sleeve 15 on the outside of the half-metal needle 7 inside the patient's body for administration. The scales on the stimulating needle body 1 and the half-metal needle 7 allow the doctor to adjust the insertion depth according to treatment needs. The angle of the half-metal needle 7 and the stimulating needle body 1 is adjusted using a level.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
