Embodiment 1
[0049] see Figure 1 to Figure 7 , the anal canal cell sampling device 1 described in this optional embodiment includes a first connecting member 2, a handle 3 and a sampling part 4 fixedly connected to both ends of the first connecting part 2 and a sampling part 4 for defining The fiber component 5 extending into the anal canal, the fiber component 5 is slidably sleeved on the first connecting piece 2, the outer surface of the sampling part 4 is covered with soft hairs 6, the The soft hairs 6 are wavy, and the soft hairs 6 are arranged along the radial direction of the sampling part 4 .
[0050] Based on the above structure, when using the anal canal cell sampling device 1, the patient's hand needs to be held on the handle 3 of the device, so that the sampling part 4 can be aligned with the anus, and the patient gradually moves forward while holding the handle 3 Advance, so that the sampling part 4 slowly enters the inside of the anal canal, and the handle 3 pushes the sampl...
Embodiment 2
[0063] see Figure 8 with Figure 9 , the difference between this embodiment and Embodiment 1 is that the sampling assembly of this embodiment includes a second connection ring 55 and a second connection piece 56, the second connection ring 55 is sleeved on the first connection piece 2, and the second connection The outer diameter of the ring 55 is larger than the outer diameter of the sampling part 4, that is, the outer diameter of the second connecting ring 55 is larger than the positioning hole 81 and the limit hole 91 of the introduction dilator 7, so as to be able to achieve a blocking effect in the process of pushing forward , to avoid the phenomenon that the insertion is too deep or insufficient; the second connecting member 56 has two ends, the first end of the second connecting member 56 is fixedly connected with the connecting ring, and the second end of the second connecting member 56 is fixed Connected to the handle 3, the second connecting ring 55 reciprocates on...
