[0002] The breast excision probe is mainly used in minimally invasive breast excision. It is a minimally innovative technology that combines the three advantages of "painless, minimally invasive, and cosmetic". The breast excision probe passes through a skin incision less than 5 mm and accurately reaches the target lesion under the guidance of ultrasound positioning. Using negative pressure suction, the excision probe sucks the lesion tissue into its collection tank, and then the tissue is removed and transported out of the body through the excision and vacuum transportation system. This process is repeated until the lesion is completely removed under color ultrasound.

[0003] The breast excision probe is composed of an outer needle tube and an inner needle tube. During the assembly and production process of the breast excision probe, the outer needle tube of the probe needs to be verified first before the assembly work can be carried out. However, the verification assembly device currently developed and used by us can only perform the positioning and assembly of a single outer needle tube, which still affects the efficiency and speed of the assembly and does not have the function of simultaneously positioning and assembling multiple outer needle tubes. Therefore, it is urgent to improve the existing outer needle tube positioning and assembly device and provide a breast excision probe outer needle tube positioning and assembly device.

[0027] In this embodiment, the multiple grooves 4 are provided to facilitate the installation and stable operation of the assembly positioning component 5 .

[0028] Based on the above structure, the assembly positioning component 5 includes a first screw rod 51, a stop block 52 and a butterfly nut 53. The bottom end of the first screw rod 51 is fixedly connected to the inner bottom of the groove 4. The outer sliding sleeve of the first screw rod 51 is provided with a stop block 52, and a butterfly nut 53 is provided above the stop block 52. The butterfly nut 53 is threadedly sleeved on the outer side of the first screw rod 51.

[0029] Based on the above structure, the longitudinal section of the stopper 52 is an inverted "E"-shaped structure, the front end width of the stopper 52 is gradually decreasing from top to bottom, and the rear end of the stopper 52 is slidably connected to the vertical plate 3 through the groove 4.

[0030] In this embodiment, the stopper 52 is provided to facilitate positioning of the outer needle tube body 11, and the butterfly nut 53 is used to facilitate pressing the stopper 52 from above.

[0031] Based on the above structure, the assembly and placement component 8 includes an adjustment plate 81, a limit groove 82, an upper assembly groove 83 and a lower assembly groove 84. The adjustment plate 81 is snap-fitted and slidably located on the inner side of the slide groove 2.

[0036] The working principle of the utility model is as follows:

[0037] When in use, first manually rotate the second screw rod 6 according to the length of the assembled outer needle tube body 11, control the connecting frame 7 to drive the adjustment plate 81 to move stably on the inner side of the slide groove 2 in the direction away from the vertical plate 3. When the adjustment plate 81 moves to a suitable position, the first tightening knob 9 and the second tightening knob 10 can be tightened to press the adjustment plate 81 from above. By adjusting the adjustment plate 81, it is convenient to position and assemble outer needle tube bodies 11 of different lengths. Rotate the butterfly nut 53 to raise it to the outside of the top of the first screw rod 51, and manually lift the inverted "E"-shaped stopper 52 upwards. After the outer needle tube body 11 is placed in the upper assembly groove 83, the stopper 52 is moved down to reset it. Figure 2 As shown in , the front end of the stopper 52 can be made to abut against the rear end of the cutting groove at the end of the outer needle tube body 11, and the butterfly nut 53 can be reversed to press the stopper 52 from above, so that the outer needle tube body 11 can be firmly positioned, which is convenient for subsequent assembly work;
