[0035] The support part 100 serves as the basis of the puncture needle assembly for cytopathology detection;

[0036] The rotating part 200 includes a working arm 210 and a connecting column 220. The connecting column 220 is plugged and rotatably connected to the supporting part 100. The working arm 210 is connected to the upper end of the connecting column 220.

[0037] The electromagnetic member 300 is disposed on the support portion 100 and matches the connecting column 220, wherein when the electromagnetic member 300 is energized, the connecting column 220 is restricted from rotating;

[0038] The B-ultrasound fixing part 400 includes a B-ultrasound mounting seat 410 and a locking device 420. The B-ultrasound mounting seat 410 includes a base section 411 and a movable section 412 movably connected to the base section 411 in the length direction. An elastic member 413 is provided between the base section 411 and the movable section 412 to press the movable section 412 out of the base section 411. The base section 411 is hinged to the working arm 210. The locking device 420 is used to fix the base section 411 to the working arm 210. The free end of the movable section 412 is used to install an external B-ultrasound probe.

[0039] The puncture needle fixing part 500 is connected to the free end of the working arm 210 and extends downward, and the free end of the puncture needle fixing part 500 is hinged with a puncture needle mounting seat 510;

[0040] The puncture needle part 600 can be detachably mounted on the puncture needle mounting seat 510 .

[0041] In the prior art, since the B-ultrasound probe and the puncture needle need to be operated at the same time, it causes inconvenience in the use process and is not conducive to the accurate implementation of the puncture sampling process.

[0042] In the present invention, the support part 100 is the basis of the puncture needle assembly for cytopathology detection. The support part 100 can be set on the bed 010 or on the ground, and the corresponding fixing structure can be set. For example, when the support part 100 is fixed on the frame of the bed 010, a track is set corresponding to the support part 100, and the support part 100 can be fixed on the track and can also be transferred.

The B-ultrasound mounting seat 410 includes a base section 411 and a movable section 412 movably connected to the base section 411 in the length direction. An elastic member 413 is provided between the base section 411 and the movable section 412 to press the movable section 412 out of the base section 411. Considering that the B-ultrasound probe needs to be in continuous contact with the skin during use, the elastic pressing of the B-ultrasound probe is completed by the elastic setting of the B-ultrasound mounting seat 410. The combination mode between the base section 411 and the movable section 412 can be various. The movable section 412 is movably connected to the base section 411 in the length direction, but the movable section 412 will not be out of the base section 411. The elastic member 413 makes the movable section 412 tend to be outward. The base section 411 is hinged to the working arm 210, and the locking device 420 is used to fix the base section 411 to the working arm 210.

The puncture needle part 600 is detachably mounted on the puncture needle mounting seat 510. The rotation of the puncture needle mounting seat 510 provides flexibility for the working angle of the puncture needle part 600.

[0047] In summary, the connecting column 220 is plugged and rotatably connected to the support part 100, and the rotation of the rotating part 200 can not only achieve the storage effect, but also achieve the adjustment of the working position; the electromagnetic component 300 is arranged on the support part 100 and matches the connecting column 220, and when the electromagnetic component 300 is energized, it limits the rotation of the connecting column 220; then through the elastic setting of the B-ultrasound mounting seat 410, the elastic pressing of the B-ultrasound probe is completed, and the rotatability of the B-ultrasound fixing part 400 provides flexibility for the working angle of the B-ultrasound probe; through the rotation of the puncture needle mounting seat 510, flexibility is provided for the working angle of the puncture needle part 600.

[0048] Reference Figure 4 In one embodiment, the connecting post 220 extends into the supporting portion 100 , and the electromagnetic member 300 is disposed corresponding to the bottom of the connecting post 220 and forms contact therewith.

It should be noted that the layout of the switch part needs to avoid interference with the rotation of the rotating part 200. In some embodiments, the working mode of the switch part can be wireless.

[0052] In one embodiment, the fixed position of the B-ultrasound mounting base 410 in the length direction of the working arm 210 is adjustable.

[0053] In this embodiment, considering that the puncture needle fixing part 500 is at the free end of the working arm 210, which facilitates the operation of medical staff, the position of the B-ultrasound mounting seat 410 is set to be movable, so that the position between the B-ultrasound fixing part 400 and the B-ultrasound fixing part 400 is adjustable, which can adapt to more working environments and provide medical staff with greater working flexibility.

[0054] In one embodiment, both the B-ultrasound mounting seat 410 and the puncture needle mounting seat 510 are provided with angle indicating structures.

[0055] In this embodiment, by adding an angle indicating structure, the working angles of the B-ultrasound mounting seat 410 and the puncture needle mounting seat 510 can be indicated, thereby improving the accuracy of the puncture work and reducing the risk of repeated attempts. During a use process, after a B-ultrasound scan is performed in advance, a preliminary calculation is performed first to obtain the working angles of the B-ultrasound mounting seat 410 and the puncture needle mounting seat 510, and then the angle adjustment is completed under the guidance of the angle indicating structure. Through the above structure, the working accuracy of the entire assembly is improved.

[0056] Reference Figures 5 to 7 In one embodiment, the fixed position of the connecting column 220 in the length direction of the working arm 210 is adjustable.

[0057] Due to the different positions of puncture sampling, the connection between the connecting column 220 and the working arm 210 is set to be movable, so that the corresponding positions of the B-ultrasound fixing part 400 and the puncture needle fixing part 500 can be diversified to meet different usage requirements. The connecting column 220 can be fixed on the working arm 210 in various ways, such as using bolts.

[0059] In this embodiment, the support part 100 is divided into a base 110 and a support column 120, and the support column 120 provides height, so that the height of the connecting column 220 can be reduced, thereby improving the working stability of the rotating part 200. For example, the upper surface of the support column 120 is provided with a mounting groove 121 extending downward, and the connecting column 220 is installed in the mounting groove 121 above.

[0060] Reference Figure 4 In one embodiment, the length of the support 120 is adjustable.

[0061] In this embodiment, the height of the working arm 210 is changed by adjusting the length of the support 120. The working height of the B-ultrasound and the puncture needle 600 can be changed accordingly, thereby adapting to different working heights.

[0062] In one embodiment, a transfer wheel is disposed at the bottom of the support portion 100 , and a brake structure is disposed on the transfer wheel.

[0063] In this embodiment, the support part 100 is movable by the transfer wheel, so that the entire cytopathology detection puncture needle assembly can be transferred to a suitable position relative to the bed 010, thereby facilitating the operation on the patient. Accordingly, a brake structure is provided on the transfer wheel, and after being transferred to a suitable position, the support part 100 is fixed by the brake structure to reduce the risk of abnormal movement.

[0064] Reference Figure 1 In one embodiment, a track 130 is provided corresponding to the support portion 100 , and the fixed position of the support portion 100 in the length direction of the track 130 is adjustable.

[0065] In this embodiment, the position adjustment of the support part 100 is more standardized by setting the track 130, and it is not easy to have abnormal sliding and the like.
