Sampling device for cervical cancer screening

Abstract

The invention provides a sampling device for cervical cancer screening and relates to the technical field of medical instruments. The sampling device is used for solving the problem that a tremendous potential problem for health of a patient is present due to the fact that an existing uterine neck sampling device is lack of a safe extraction structure, brush hair is in direct contact with a uterine neck after a brush rod enters a human body, and the probability that the brush hair falls into the uterine neck of the patient is increased invisibly. The sampling device comprises a connecting part, wherein a control assembly is arranged in the connecting part. After the device is inserted into the body of the patient, by pushing a pull rod backwards, the pull rod can push a moving piece to move backwards, the moving piece moves backwards, a movable rod is jacked up through a connecting piece, an inserting piece with a sawtooth-shaped-structure top is arranged on the movable rod, and the top of the inserting piece can be in friction contact with the uterine neck by repeatedly pushing the pull rod, so that epithelial cells of the uterine neck are obtained; and after sampling is completed, the device is withdrawn, the inserting piece is taken down for inspection, the inserting piece is used for replacing a brush head, and thus, the risk that the brush hair falls inside a vagina of the patient to cause infection can be avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to a sampling device for cervical cancer screening. Background technique [0002] Cervical cancer is a gynecological disease that seriously threatens the life and health of patients. Therefore, it is usually necessary to perform sampling inspection for patients with cervicitis. Rub to swab off exfoliated epithelial cells and secretions and send epithelial cells and secretions for examination. [0003] For example, the application number: CN201910441020.5 relates to a cervical sampler, which includes a forceps body and a sampling structure. The sampling structure includes sampling tube I and sampling tube II. The upper and lower ends are connected, the outer diameter of the sampling tube I is not greater than the inner diameter of the sampling tube II, and the top surfaces of the side walls of the sampling tube I and the sampling tube II are respectively prov...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a sampling device for cervical cancer screening to solve the problem that the existing cervical sampling device lacks an adjustable structure. During the sampling process, due to the nervousness of the patient, the The contraction of the vaginal opening is in a closed state, which is not conducive to the doctor's observation and sampling, and the existing cervical sampling device lacks a safe extraction structure. After the brush rod enters the human body, the bristles directly contact the cervix, which virtually increases the number of bristles falling on the patient's cervix. Probability in the middle, there is a great hidden danger to the patient's health
