Abstract

The utility model discloses a cervix uteri brush, which comprises a mandrel, a bushing, and a scraping strip; a protective tube is arranged outside the bushing; the protective tube can slide axially along the outer wall of the bushing; the scraping strip consists of an elastic brush bone and brush kernels; the two ends of the elastic brush bone are respectively connected with the head end of the bushing and the head end of the mandrel; the tail end of the mandrel is provided with a control nut; and the scraping strip can be bent. When the utility model is used for sampling, the brush head is protected by the protective tube all the time when entering and getting of the cervix uteri, thus being not easy to stick sundries and ensuring the accuracy of sampling and examining.

Description

Uterine neck bush

Technical field

This reality newly belongs to technical field of medical instruments with type, specifically relates to a kind of gynecologial examination uterine cervix brush.

Background technology

Clinically, uterine cervix brush is widely used in the inspection of gynaecopathia, existing uterine cervix brush, and brush mostly is solid shape, and the outside do not have preventer, and brush becomes easily infected by foreign material during sampling, the accuracy of influence sampling and check effect.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of brush and is difficult for polluting the uterine cervix brush accurately of taking a sample.

For solving the problems of the technologies described above, this utility model comprises core bar, sleeve pipe and scraping article, its construction features is that sleeve pipe is provided with casing outward, this casing can be in axial sliding along sleeve outer wall, scraping article is made up of elasticity brush bone and bristle, elasticity brush bone two ends are connected with pin head with the sleeve pipe head end respectively, and the core bar end is provided with the control nut.

The scraping article that is located between sleeve pipe head end and pin head is formed by 4.

Also be provided with hold-down nut on the core bar of control nut outer end.

Because this utility model sleeve pipe is provided with outward can be along its outer wall casing in axial sliding, the scraping article between sleeve pipe head end and pin head is provided with elasticity brush bone, can be crooked, and scraping article is the vertical bar shape usually, and is positioned at casing.During sampling, Uterine neck bush pulls back casing after inserting cervical canal and arriving sampling point again, and scraping article is exposed, and the Spin Control nut pulls back core bar then, makes scraping article bend to arc, and rotating casing at this moment, scraping article also rotate immediately and carry out cell sampling.After the sampling, adjust the control nut and make the core bar reach, scraping article becomes vertical bar again, promotes casing then forward; make scraping article be positioned at casing, like this, brush is in turnover cervical canal process; all the time be subjected to the casing protection, be difficult for being infected with foreign material, guaranteed sampling and the accuracy of checking.
