Problems solved by technology

At the time of diagnosis, the anal canal cancer cells of the patient have often metastasized, and the method of biopsy using an anoscope is an invasive examination and is not suitable for physical examination screening
Moreover, the cost of anoscope equipment is relatively expensive and the operation is relatively complicated, so the treatment fee charged is also high, which will bring a greater economic burden to the patient; in addition, the requirements for disinfection measures for HIV or HPV are relatively strict, and the scale is generally small Most hospitals will not use anoscopy technology, which makes it very inconvenient for high-risk groups with such diseases to see a doctor and make a diagnosis, and it is easy to delay the treatment

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...

Abstract

The invention provides an anal canal cell sampling device, an introducing expander and an anal canal cell sampling method. The anal canal cell sampling device comprises a first connecting piece, a handle, a sampling part and a limiting assembly, wherein the handle and the sampling part are separately and fixedly connected to two ends of the first connecting piece; the limiting assembly is used forlimiting the extending distance of the sampling part in an anal canal, and is arranged on the first connecting piece in a sliding and sleeving manner; and soft hairs cover the outer surface of the sampling part, are wavy, and are arranged in the radial direction of the sampling part. A patient can independently complete the work of sampling cells on a mucous membrane of the anal canal through a noninvasive screening manner, so that the privacy of the patient can be protected, the patient can conveniently detect early-stage anal canal cancer and precancerous lesion, and the patient can seek medical advice in time, so that the survival rate of the patient is increased; and the whole operation process is simple and convenient.

Description

technical field [0001] The invention relates to the field of medical examination aids, in particular to an anal canal cell sampling device, an introduction dilator and an anal canal cell sampling method. Background technique [0002] According to official statistics in 2014, the number of homosexuals in China reached about 70 million and is increasing year by year. According to statistics from the Chinese Center for Disease Control and Prevention in 2016, there are about 780,000 HIV-diagnosed patients in China, and about 10% of HIV-infected people have not yet been discovered. Anal canal cancer is a rare malignant tumor. Among HIV-positive gay men, the incidence rate of anal canal cancer is 35 / 100,000, which is close to the level of cervical cancer in women. At present, it is believed that HIV infection, HPV infection and homosexuality (gay men and lesbians) belong to the high-risk groups of anal canal cancer. The prevention and detection of anal canal cancer is a multi-st...
