TCT brush for cervical thinprep cytology test

Abstract

The invention discloses a TCT brush for cervical thinprep cytology test, which comprises an operating outer rod, a pushing inner rod, a sampling insertion rod, a pushing rod and bristles, inner cavities of the operating outer rod and the sampling insertion rod are of hollow structures, the sampling insertion rod is fixedly connected to the center of the right side of the operation outer rod, the inner cavities of the operating outer rod and the sampling insertion rod are communicated, and the pushing inner rod is movably inserted into the left side of the operating outer rod. The novel TCT brush provided by the invention is scientific and practical in design concept, and according to clinical experience, cervix is narrow and small due to cicatricial contracture after the cervix LEEP operation and cervical atrophy of postmenopausal women, although an ordinary TCT brush head is triangular, the top end of the brush head is still wide, the brush head is difficult to enter the narrow and small cervix, and it is unable to obtain satisfactory cells. The center of the novel brush head is slender, the novel brush head can conveniently enter the cervical canal, the pusher is manually controlled to fix and open the brush after entering, and the satisfaction of sampling is improved.

Description

technical field [0001] The invention relates to the technical field of medical testing and sampling equipment, in particular to a TCT brush for cervical liquid-based thin-layer cell detection. Background technique [0002] Cervical cancer is a serious threat to the physical and mental health of women all over the world, ranking second in the incidence of female malignant tumors in the world. Due to the widespread application of cervical cytology screening in the past 40 years, cervical cancer and precancerous lesions can be detected and treated early. The morbidity and mortality of cancer have been significantly reduced, and regular cervical TCT combined with HPV inspection is particularly important. As an important means of treating high-grade cervical intraepithelial lesions (CIN), LEEP can not only preserve uterine and reproductive functions, but also completely remove the lesions and treat the disease in most cases. The follow-up after LEEP can not only observe the cura...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a TCT brush for cervical liquid-based thin-layer cell detection, which has the advantages of being able to sample the inside of the patient's cervix after cervical surgery, and can effectively achieve satisfaction, which solves the problem of traditional TCT brushes. It is difficult to enter the cervix for sampling after cervical surgery, and the sampling satisfaction is not good
