Description

Cervical sampling device

Technical Field

The invention relates to the technical field of medical detection instruments, in particular to a cervical sampling device.

Background

The cervix is one of important tissue organs in the female reproductive system, from an embryo and a female fetus to an old woman, relates to the disease prevention and treatment and health care problems of gynecology, obstetrics, family planning, women health care, reproductive health and the like in the female lifetime, relates to the health, family happiness, economy and social problems of the female, and is closely related to sex, reproduction and the like. The cervix can have various diseases, including embryonic dysplasia, inflammation, neoplastic lesions, benign tumors, malignant tumors, injuries, cervical infertility, family planning, assisted reproduction technology, cervical sex, cervical pregnancy, cervical dystocia and other obstetric and gynecologic problems. The cervix is an important defense against pathogens entering the internal genitalia, but it is itself subject to various pathogenic factors (female childbirth, miscarriage, surgical injury to the cervix, etc.); the cervical intima is more cracked, bacteria are difficult to eliminate after the bacteria are hidden in the cervical intima, and the cervical inflammation is very easy to cause. The disease can be divided into acute and chronic diseases, the latter is usually caused by the failure of the former to cure in time, the chronic cervicitis is more common clinically, and the most obvious symptoms are viscous white mucus or purulent yellow mucus-like leucorrhea increase, and in addition, pruritus vulvae, lumbosacral pain and the like can be accompanied.

Cervical cancer is the most common gynecological malignancy. The age of the primary cancer is 30-35 years old, the invasive cancer is 45-55 years old, and the incidence of the primary cancer tends to be younger in recent years. The widespread application of cervical cytology screening in recent decades has made cervical cancer and precancerous diseases discovered and treated in early stages, and the incidence and mortality of cervical cancer have been significantly reduced.

Pap (Pap) vaginal cell smear examination, also known as cervical smear, refers to taking a small sample of cells from the cervical part of the uterus, placing it on a glass slide, and then examining it under a microscope for abnormalities.

Pap screening requires the use of a cervical sampling device, which is currently used to clamp cervical tissue by extending through a clamp into the cervix. The clamp body is sharp outside, so that the clamp body is easy to damage when extending into a patient; in addition, in the process of removing the clip, the living tissue is likely to be dropped.
