Description

TCT brush for cervical fluid-based thin-layer cell detection

Technical Field

The invention relates to the technical field of medical detection sampling equipment, in particular to a TCT brush for cervical fluid-based thin-layer cell detection.

Background

Cervical cancer seriously threatens physical and mental health of women worldwide, the 2 nd position of the incidence rate of malignant tumors of women worldwide is established, and due to the common application of cervical cytology screening in recent 40 years, the cervical cancer and precancerous diseases are discovered and treated in early stage, the incidence rate and the death rate of the cervical cancer are obviously reduced, and the regular cervical TCT combined HPV examination is particularly important. LEEP is an important means for treating high-grade cervical intraepithelial lesions (CIN) at present, not only can the functions of uterus and fertility be kept, but also the lesions can be completely removed to treat diseases under most conditions. The follow-up visit after LEEP operation can observe the curative effect of treating the lesion before cervical cancer, the prognosis of the lesion and early and timely discovery of cervical infiltrating carcinoma, and can effectively lead the discovery time of the cervical cancer to be earlier and lead the diagnosis period to be earlier. The scholars think that the patients after the cervical conization are best to follow up by adopting a method of colposcopy and cervical tube sampling.

However, after cervical LEEP operation or other cervical surgeries, the cervical deformation is reduced, and even the cervical deformation is needle point appearance, and the conventional TCT brush is difficult to get into the cervical canal in the current market, and the sampling satisfaction is not good enough, thereby causing the unsatisfied drawing of materials, affecting the screening effect, and causing the missed diagnosis, so a novel cervical fluid-based thin-layer cell detection TCT brush which can sample the inside of the cervix of a patient after the cervical surgeries and can effectively reach the satisfaction needs to be designed.
