Uterine cervix brush

Abstract

The invention relates to a cervix brush, comprising a sheath tube, a core pole, a scraper, villus and a guiding head; wherein, the scraper, the guiding head and the sheath tube are formed by integrated injection molding, the guiding head is arranged at the foremost end of the sheath tube, the scraper comprises six plastic strips which can be detached to triangles, the front end of the scraper is connected with the guiding head, the back end of the scraper is connected with the sheath tube and a easy folded groove is arranged between the connection and the scraper, the core pole is axially sleeved in the sheath tube and is slideable, the head of the core pole is fixed in the guiding head, the villus is cultivated at the front ends of the guiding head, the scraper and the sheath tube, the stress on the surface of the cervix from the six scrapers which can be furled and spread is uniform, in particular that the cells at area with high incidence of the cervical cancer from the one third part outside of the cervical canal to the external cervical orifice can be gotten by the cervix brush. The cervix brush has the advantages of small radial direction size, convenient operation and low manufacturing cost.

Description

technical field [0001] The present invention relates to medical devices, in particular cervical brushes. Background technique [0002] Cervical brushes are often used in gynecological cytology examinations. The cervical brushes of the prior art are mostly conical brushes in the early stage, and later developed cervical brushes with "mountain"-shaped heads. The typical structure can refer to Chinese patent ZL93239687 .9, ZL99256988.5, ZL01240267.2, ZL03221231.3, ZL200520045997.9, ZL200610005418.7, etc. In addition, cervical brushes of various structures are also disclosed in U.S.PAT.No.4759376, U.S.PAT.No.5370128 and other patents. The bristles of the cervical brush in the prior art are relatively long, and the strength of contacting the surface of the cervix is ​​uneven, and the number of cells obtained is small, especially it is not easy to obtain the high-incidence area of ​​cervical cancer from the outer 1 / 3 of the cervical canal to the external os of the cervix. cell. ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a new type of cervical brush, which overcomes the long bristles of the cervical brush of the prior art and uneven contact with the surface of the cervix; the number of cells obtained is small; it is not easy to get outside the cervical canal. / 3 to the cells of the high-incidence area of ​​cervical cancer, the external os of the cervix; and the disadvantages of large radial size and inconvenient operation
