Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a uterine cervical canal scraper. Background Art

[0002] Endocervical curettage (ECC) is a biopsy device for diagnosing the presence of lesions or cancer in the endocervical canal. A small curette is inserted into the endocervical canal to fully scrape the endocervical canal for 1-2 weeks, and tissue is obtained for pathological examination. According to the requirements of "Female Reproductive Tract Pathology", ECC specimens include cervical tissue fragments, blood, and mucus. To avoid the loss of tiny tissues, clinicians should collect and concentrate specimens (including mucus and blood). On the other hand, to avoid missing deep lesions in the endocervical canal, the small curette should reach a certain depth during ECC, and the depth is generally 2-3 cm.

[0003] The most commonly used cervical canal scraper in clinical practice is not designed with a reasonable structure and is inconvenient to operate. Specifically, (1) the existing scraper is usually a hollow ring scraper, which can only collect a limited amount of cervical canal tissue. Most of the scraped tissue will adhere to the original position of the cervical canal. After the scraping is completed, medical staff need to use other instruments (such as cotton sticks, tissue forceps, etc.) to collect cervical tissue specimens, which is time-consuming. (2) The ring edge of the hollow ring scraper is smooth, and its scraping strength on the cervical canal tissue is limited. Utility Model Content
