[0031] Need to explain, work, the needle tube 12 is aligned with the sampling point of the patient, and the depth of the puncture is confirmed by the ultrasonic imaging device, and then the position of the control device 5 on the needle tube 1 is adjusted, and then the pushing device 3 is controlled to a distance, and then the puncture needle 2 is controlled to a puncture depth, and then the pushing device 3 is pushed to the puncture point, so that the puncture needle 2 penetrates into the sampling point of the tongue, and then the puncture needle 2 is extracted from the body after sampling is completed, and then the sample in the puncture needle 2 is pushed out by the sample taking device 4, by setting the pushing device 3, the moving distance and speed of the puncture needle 2 can be accurately controlled, the introduction of the control device 5 further enhances the controllability of the operation, and medical staff can accurately adjust the pushing distance of the pushing device 3 according to the needs, so as to meet the puncture needs of different patients, so as to ensure the stability and accuracy of the puncture process, effectively reduce the trauma to the patient, and the design of the sample taking device 4 can be easily pushed out from the puncture needle 2, avoiding the problem that the sample is difficult to take out in the traditional method, and improving the efficiency and success rate of sampling.

[0032] In an embodiment, the upper end of the needle tube 1 is threadedly connected with a top cover 13, and the lower end of the needle tube 1 is provided with a bottom cover 14, and the top cover 13 is provided with a handle 11.

[0033] In this way, referring to Figures 1-8 , the threaded connection design makes the assembly and disassembly between the top cover 13 and the needle tube 1 simple and fast, which is convenient for preparation before use and cleaning and disinfection after use, improves the use efficiency and reusability of the device, and the handle 11 provided on the top cover 13 provides a convenient gripping point for medical staff, so that the entire device can be more stably controlled during puncture sampling, reducing the operation difficulty and improving the operation accuracy and comfort.

[0034] In an embodiment, the pushing device 3 includes an extrusion rod 31 penetrating through the top cover 13, an extrusion block 32 fixed at the lower end of the extrusion rod 31, and a pressing block 34 fixed at the upper end of the extrusion rod 31, the puncture needle 2 is fixed at the lower end of the extrusion block 32, the puncture needle 2 is sleeved with an elastic element 33 between the extrusion block 32 and the bottom cover 14, the elastic element 33 is made of a spring with damping or an elastic pad, and the extrusion rod 31 is provided with a scale line 311.

[0035] In this way, referring to Figures 1-8, the medical staff only needs to press the pressing block 34 to press the extrusion rod 31, so that the puncture needle 2 is smoothly pushed, and the control device 5 can accurately control the pushing depth of the puncture needle 2, so as to ensure the accuracy and consistency of sampling, avoid sampling failure or patient injury caused by improper puncture depth, and extrude the elastic element 33 during the downward movement of the extrusion block 32.
